Title: Manufacture of fiber grating
Inventor: KOMOTO KATSUTOSHI
IPC: G02B6/02
Filed: 1997-06-17
Abstract: PROBLEM TO BE SOLVED: To prevent an optical characteristic of fiber grating from deteriorating by putting an ultraviolet laser light irradiated part in an atmosphere kept within a specific temperature range. SOLUTION: An enclosure 30 having a window 32 is provided around a bare fiber 12 and a phase mask 20, and one end of a heat pipe 34 is cooled down with mixture body 36 of ice and water, which keeps an ultraviolet laser irradiated part at 0 deg.C to 10 deg.C. And the fiber grating is manufactured by emitting the ultraviolet laser 22. A bare fiber 12 densely doped with Ge for an enhancement in an optical reaction is used. Moreover, this method is applicable also when the grating is manufactured by making use of interference fringes without using a phase mask 20.  Since the temperature of the ultraviolet laser light irradiated part is kept at 0 deg.C to 10 deg.C, even if the bare fiber 12 is irradiated with the ultraviolet laser light 22 and increased in the temperature, the heat is radiated immediately without causing thermal expansion, and therefore, positional variation with respect to the phase mask is prevented.

Filed: 1995-07-12
Abstract: PROBLEM TO BE SOLVED: To enable the effective removal of surface contaminants and facilitate the removal of a silicon oxide film formed in areas where it should not exist, by, while applying oxidizing gas to the surface of a workpiece, burning and removing surface contaminating organic substances, and thereafter, while supplying reducing gas, performing heat treatment. SOLUTION: After a wafer substrate 10 is placed in a CVD furnace, the interior of the CVD furnace is evacuated and put under reduced pressure. Oxygen, an oxidizing gas, is introduced to burn and remove organic substances 12 on the surface of the wafer substrate 10. As the result of the combustion and removal of the organic substances, a silicon oxide film 11a is formed on the surface of the wafer substrate 10 positioned at the bottom of a contact hole. Nitrogen gas is substituted for the gas in the CVD furnace. Thereafter, hydrogen gas is introduced into the CVD furnace to chemically reduce and remove the silicon oxide film 11a.  This makes it possible to remove the contaminating organic substances 12 from the surface of the wafer substrate 10 under processing, and allows no silicon oxide layer 11a to be present on the surface of the wafer substrate 10 at the bottom of the contact hole.

Title: Speed detecting device
Inventor: NAKAJIMA KAZUMITSU
IPC: G01S17/58
Filed: 1988-07-14
Abstract: PURPOSE:To detect the speed of a high speed moving body by executing pulse measurement for the period of a different signal between a sub signal and a reflected signal from the moving body. CONSTITUTION:An optical modulating light 103, to which amplitude modulation is executed, is outgoing as an output light 109 and hits a moving body 5. Then, the light is reflected. With receiving Doppler shift which is proportional to the speed of the moving body, a reflected light 104 is made incident on an optical detector 6 and a detecting signal 105 is outputted and inputted to a mixer 7. Then, the mixer 7 mixes a sub signal 106 and the detecting signal 105 and outputs a different frequency signal 107. Since the different frequency signal 107 goes to be the frequency of the sub signal 106 - (a modulating signal 102 + the Doppler shift), the pulse measurement is executed for a pulse counter 9 and the speed change of the moving body can be detected.

Title: Ion generator
Inventor: TSUCHIYA MASAHIKO
IPC: H01J49/14
Filed: 1981-11-04
Abstract: PURPOSE:To increase the produced amount of sample ions greatly, and improve the sensitivity of a mass spectrograph or an ionization detector exceptionally from that of the conventional one by fixing a sample to a holding member having many projections, and applying a high voltage to said holding member. CONSTITUTION:Since a sample is fixed to and held by a member having a number of pin-line projections 21, to which a high voltage is applied, an exceptionally strong electric field exists around the projections 21, and the sample surface is exposed to the strong electric field. Therefore, molecules of the sample, after receiving the energy of Ar* (11.55eV or 11.72eV) by touching Ar*, are immediately ionized, and rapidly eliminated from the surface due to the strong electric field. As a result, a remarkably increased amount of sample ions can be eliminated by the application of the high voltage, compared to the amount of sample ions eliminated when the same amount of Ar* is applied without any application of high voltage. In addition, in this invention, since the sample is fixed to and held by the many pin-like projections 21, the surface area of the sample (the contact area between Ar* and the sample) is increased, and the produced amount of sample ions is increased in this connection too.

Title: Method for decoding servo information of information recording medium
Inventor: SUGAWARA TAKAYUKI
IPC: G11B21/10
Filed: 1996-07-05
Abstract: PROBLEM TO BE SOLVED: To prevent erroneous decoding of servo information recorded on an information recording medium after the information is encoded by reading out the information by using a successively cycle-changed encoding clock generated in a prescribed period. SOLUTION: When servo information is decoded, a clock signal generating circuit 10 generates a multiplied encoding clock signal in a period T/N which is 1/N (N: an integer of >=2) time as short as the period T of an encoding clock signal used at the time of encoding the servo information. A servo decoding circuit 9 reads out the servo information recorded the read section of each track of an information recording medium 1 by using the encoding clock signal by using the successively cycle-changed encoding clock signal generated from the circuit 10. A servo timing generating circuit 11 sets the operating timing of each section under the control of a CPU 8 based on the decoded servo information. Therefore, the servo information can be read out accurately, because one servo information is read out N times.

IPC: G02B6/32
Filed: 1986-07-29
Abstract: PURPOSE:To improve the coupling efficiency by using a plane plate-shaped micro Fresnel lens as a condenser/collimator lens. CONSTITUTION:A micro Fresnel lens 3 formed on a transparent supporting cylinder body 2 is attached and fixed to the front end of an optical fiber 1. The spread light beams emitted from the optical fiber 1 are collimated by the Fresnel lens 3 and are emitted to the outside. Parallel light beams from the outside are condensed by the lens 3 and are made incident on the core of the optical fiber 1. A female mold of a preliminarily produced micro Fresnel lens is used to form this micro Fresnel lens 3(2) into one body with a transparent synthetic resin. For example, an electron beam resist is applied on a prescribed substrate, and a micro Fresnel lens pattern is drawn on the resist by electron beam drawing, and this resist is developed, and the remaining film resist pattern on the substrate is transferred to the substrate by dry etching to obtain the substrate as the female mold. Thus, efficient coupling is possible.

Title: Multipurpose noise eliminating circuit
Inventor: KATOU KENJI
IPC: H04B1/12
Filed: 1980-12-15
Abstract: PURPOSE:To eliminate the noise effectively with a minimum number of constituents, by adding a signal, which is obtained by inverting a signal where a prescribed signal band is eliminated from an input signal, to the input signal when the noise exists. CONSTITUTION:When the noise does not exist, a switch SW5 is closed by the control system. Consequently, the signal path consisting of a phase inverting circuit 11 and a pass signal control circuit 12 is grounded, and a signal supplied to an input terminal IN is outputted to an output terminal OUT through a combined resistance 18. When the noise is mixed with the coming signal, the switch SW5 is opened. The output of an LPF10 has the phase inverted by the circuit 11 and has a prescribed signal band such as a main signal frequency band stopped by the circuit 12 and is supplied to the combined resistance 18. Consequently, the output of the LPF10 and a signal, which is obtained by eliminating a prescribed signal band of the main signal from the output of the LPF10 and inverting the phase, are synthesized by the resistance 18. Thus, the noise mixed outside the prescribed signal band is cancelled and eliminated.

Filed: 1998-06-24
Abstract: PROBLEM TO BE SOLVED: To increase the number of relieves of error bits when one threshold voltage changes successively along the threshold voltage levels corresponding to the plural conditions that can be displayed by multiple bit data by changing only one of the corresponding data bits. SOLUTION: Suppose that a multiple level memory is provided with the threshold voltage levels distributing at a specified interval in correspondence to four possible states A-D which display two-bit multiple bit data. For example, based on technique 1, '11', '10', '00', '01' of bit data are successively allotted from the lowest threshold voltage level toward higher levels. When, for example, the threshold voltage level of the cell storing '10' ascends in external factors or reliability data, only one bit changes for the bit data corresponding to the former threshold level.

Title: Hot water storage type hot water supply equipment
Inventor: FUJISHITA KAZUO
IPC: F24H1/18
Filed: 1980-12-16
Abstract: PURPOSE:To enable to efficiently obtain high temperature water and to economically use it by a method wherein the outlet part of a hot water storage tank is divided  into two circuit or an instantaneous use circuit with a high riser and a uniformly distributing circuit with a low riser at the captioned hot water supply equipment, in the system of which a heat exchanger and the hot water storage tank are separated with  each other. CONSTITUTION:The combustion gas of a burner 15 is discharged to an exhaust top 26  by means of a blower 22. Meanwhile, the waters flowing through inlets 13 and 14 are  heat-exchanged at finned pipes 2 and 7 so as to become high temperature water and  sent through a header 4, outlet part 10, the instantaneous use circuit 30 and the uniformly distributing circuit 28 to the hot water storage tank 11. Immediately after the  heating is started, the high temperature water layer is generated at the upper part of  the tank 11 and, at the lower part of the tank 11, the low temperature water is heat- exchanged with the high temperature water. Consequently the natural convection is  generated at the lower layer of the upper high temperature water layer, resulting in  uniformalizing the hot water in the tank 11 with the elapse of heating time. When the  hot water is uniformalized, a hot water thermostat actuates to stop the combustion of  the burner 15. In such a manner as described above, energy-saving can be accomplished  and the command of the equipment can be acquired.
