Title: Rydberg atom impact type ion source
Inventor: KONDO TAMOTSU
IPC: G01N27/62
Filed: 1989-12-22
Abstract: PURPOSE:To allow negative ions of a sample to exist in a stabilized state by making a grid of Rydberg atom generator needle-like and providing a cooling means in an ion source block. CONSTITUTION:In an ion source of a mass spectrometer where sample molecules of gas are made collide against Rydberg atoms to ionize a sample for mass analysis, a grid 6 of a Rydberg atom generator 3 of an ion source block is made needle-like as well as a cooling means 9 is provided on the ion source block. That is, by making the needle-like grid 6, discharge caused by deposition of atoms sputtered from a filament 5 is eliminated and further concentration of thermions in the vicinity of the grid 6 can be raised. In addition a rise in temperature of the ion source block is suppressed by providing the cooling means 9, so that decomposition of the sample and decomposition of generated ions can be suppressed to raise generation efficiency of parent molecule ions of the sample. Thus negative ions of the sample are allowed to exist for a long time in a stable state.

Title: Method and system for restoration of timing
Inventor: SAMII SHIYUE
IPC: H04L7/027
Filed: 1992-12-11
Abstract: PURPOSE: To provide a device and a method for receiving a continuous time pulse amplitude-modulated pass-band signal including local clock synchronous technology. CONSTITUTION: A pulse-amplitude modulated signal is sampled periodically with a lock clock 58 in order to generate received samples. In order to lead out the corrected samples, convolution and impulse response functions of the received samples are evaluated with a specific value of a phase difference variable. A filter 68 with a narrow transmission band is used and a periodic signal is led out from the corrected samples. This periodic signal has a period equal to a symbol period of a pulse amplitude modulated signal. A series of the samples in each period of the periodic signal is compared so as to discriminate whether the corrected samples are delayed behind or preceded to the optimum samples. When the corrected samples are delayed behind or preceded to the optimum samples, the phase difference variable used for evaluating the convolution is changed by fixed discrete step size.

Title: Diffraction grating
Inventor: IIDA MASANORI
IPC: G02B5/18
Filed: 1987-12-28
Abstract: PURPOSE:To widen the wavelength range in which a diffraction efficiency by a non-deflection becomes high and to reduce the polarization dependency by constituting the title diffraction grating of a substrate, a photosensitive layer and a reflecting film, so that the photosensitive layer has such a sensitivity characteristic as a second order derivative of a curve for showing the exposure quantity and the residual film thickness rate of a photosensitive layer film after the development becomes a positive value. CONSTITUTION:The contrast of an interference fringe exposed to a photosensitive layer 12 on a substrate 13 generally becomes a trigonometrical function as shown by an intensity distribution 21, and as for a sensitivity curve 23, since a secondary differentiation of its curve is a positive value, as the exposure quantity becomes large gradually, a variation of the residual film thickness rate of the photosensitive layer against it becomes low. Accordingly, when the exposure is executed by an interference fringe of the intensity distribution 21, a diffraction grating having a grating cross-sectional shape after the development is obtained, and by providing a reflecting film 11 thereon, a reflection type diffraction grating is formed. As for the grating shape, a crest part of a grating groove is sharp, and a valley part becomes round. The diffraction efficiency of such a diffraction grating is a non- polarization and high within a range in which lambda/d is 0.7-1.1, and the polarization dependency does not appear remarkably so much either when lambda/d is <=1.1. In such a way, the diffraction efficiency being a non-polarization and high is realized extending over a wide wavelength range, and also, a deviation of the diffraction efficiency by each polarization can be reduced.

Title: Method and apparatus for detecting hidden position
Inventor: NAKAUCHI HIROMASA
IPC: G01V3/12
Filed: 1998-11-07
Abstract: PROBLEM TO BE SOLVED: To make detectable three-dimensional position of a leading end part of a propulsion unit of an underground digging method from above the ground. SOLUTION: A transmitting antenna 16a is set to a leading end part 9 of a propulsion unit 2 thrusting in a soil. When a transmission signal as a continuous carrier wave is fed to the transmitting antenna, the transmitting antenna generates an electromagnetic wave into the soil. A reflected wave of the electromagnetic wave by an underground buried object is received by receiving antennas 16b1-16b5 at least at three set positions on the ground. A time difference of the transmission signal fed to the transmitting antenna and a reception signal at each set position corresponds to a distance between the transmitting antenna and the set position of the receiving antenna. A three-dimensional position in the soil of the transmitting antenna can thus be detected.  The transmission signal as the continuous carrier wave fed to the transmitting antenna may be modulated in amplitude, for example, with information expressing a reflect time of the underground buried object or the like, so that the information can be transmitted with use of the electromagnetic wave from the transmitting antenna.

Title: Transmitting destination designating system in multiprocessor system
Inventor: KONUKI MASATO
IPC: G06F15/177
Filed: 1991-12-17
Abstract: PURPOSE:To shorten processing time by simplifying the processing procedure of a transmitting side, and simultaneously, transmitting data to both systems at a time. CONSTITUTION:In the case of transmission to a duplex processor, the address of whichever processor is set, the data can be transmitted to the system desired to transmit. Here, in the case that the processor 41 is of an ACT system, and the processor 30 designates the processor 40 as the address of the transmitting destination processor, the address checking function part 40a of the processor 40 compares the transmitting destination address of the data on a bus line 26 sent from the processor 30 with the contents of a both-system address memory 40c, and detects coincidence with the address of its own processor. Then, a system checking function 40b decides that it is not the data addressed to itself because the designation of the transmitting destination system shows the ACT system, and it does not coincide with its own processor.

IPC: G01R19/165
Filed: 1990-11-28
Abstract: PURPOSE:To reduce the consumed current by providing a liquid crystal plate between light emitting and light receiving elements. CONSTITUTION:Voltage applying terminals 11a, 11b of a liquid crystal plate 11 are connected to a power source to be detected 12, and the output voltage is applied to the liquid crystal plate 11. When the output voltage is held within a normal range at the voltage threshold value V2 or above, the liquid crystal plate 11 interrupts a luminous beam from a light emitting element 13, and a light receiving element 14 is switched off. The DC voltage Vd of an output terminal 18 becomes +5V. When the output voltage is lowered to the threshold value V1 or below on the contrary, the light permeability of the liquid crystal plate 11 is increased, the element 14 is switched on, and the voltage Vd of the terminal 18 becomes +0V. The output voltage state of the power source 12 can be detected in the electrically insulated state from the power source 12. The liquid crystal plate 11 has high impedance, the change of the light permeability is determined by the applied voltage value, the power consumption on the power source 12 can be made very small.

Filed: 1989-12-25
Abstract: PURPOSE: To precisely control fuel injection quantity by closing a first solenoid valve again at an interval of filling a storing chamber controlled by the first solenoid valve when a storing piston reaches a target value. CONSTITUTION: A first solenoid valve 45 is opened under the control of a control device 75, allowing the high pressure fuel from a pump 1 to flow into a fuel storing chamber 38 from a high pressure accumulating chamber 16, resulting in pushing up a reservoir piston resisting to a spring 63. When the moving distance detected by a distance pulse generator 68 thus reaches a target, that is a criterion of fuel quantity, the first solenoid valve is closed, finishing the filling of the fuel storing chamber 38. In the next step, at the time of the start of fuel injection, a second solenoid valve 52 is opened to send fuel from the fuel storing chamber 38 to an injection valve 25 through a connection pipe 24. In this case, intermittent fuel injection becomes possible by controlling the opening and closing the second solenoid valve 52. Injection fuel quantity can thus be controlled precisely.

Title: Optical attenuator and its production
Inventor: PARK CHAN-SIK
IPC: G02B6/26
Filed: 1997-12-03
Abstract: PROBLEM TO BE SOLVED: To facilitate the extra length treatment and management of an optical cable in an optical distributor and to reduce a cost by forming plural diffraction gratings to change the total reflection condition of a core layer to an optical fiber. SOLUTION: A first connector 16 and a second connector 18 are connected by the optical cable 100. The outer layer of the optical fiber 12 of the optical cable 100 is covered with a tube 14 for protection. The plural diffraction gratings 10 which attenuate incident light by changing the refractive indices of the core layer and the clad layer to destroy the total reflection condition are formed in the optical fiber 12 at specified intervals by using an excimer laser. Namely, when the optical fiber 12 is irradiated with the strong excimer laser, the refractive index is changed by the ion recoupling arising from the receipt of the light energy in the ions deposited by evaporation on the core layer. The total reflection condition by the refractive index difference between the core layer and the clad layer is destroyed and the diffraction gratings 10 are formed.  In such a case, the light attenuation quantity is controllable according to the irradiation time and irradiation area of the laser.
