Title: Spectroscope for monitoring electric communication signal
Inventor: FORD JOSEPH EARL
IPC: H04B10/29
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To obtain perfect and detailed data on each WDM signal by a method wherein signals are processed by detectors that detect each at least signal of a certain wavelength linearly and processor chips provided integrally with the detectors. SOLUTION: For instance, by use of a free spatial optics, signal wavelengths of WDM signals inputted through one or more input fibers are dispersed or demultiplexed on detector/processor chips. The above signals are received through an input fiber array 301 composed of M fibers. An optical output from the fiber array 301 is collected on a planar diffraction grating 303 through a collimating lens 302. The planar diffraction grating 303 diffracts the optical signals and returns them to the collimating lens 302, and the optical signals are collected on an opto-electronic chip 304. The opto-electronic chip 304 comprises a two-dimensional array of detectors and detects light signals. Then, the signals are processed with processor chips provided integrally with the detectors.

Inventor: WAKAMOTO KATSUYOSHI
IPC: B22D11/04
Filed: 1981-04-30
Abstract: PURPOSE:To prevent the intrusion of oxygen into a graphite mold and to make continuous casting possible by opening a through-hole in the inside circumferential surface of the mold, and feeding a protecting atmosphere gas to the solidification interface between a molten alloy and the graphite mold. CONSTITUTION:A through-hole 6 is opened in the inside circumferential surface of a graphite mold 1, and gaseous N2 or a gas of the same function as that of said gas is fed as a protecting atmosphere gas to the solidification interface between a molten alloy 3 and the mold 1 through the hole 6. The intrusion of the atmospheric air through the ingot outlet of the mold 1 into the mold 1 is prevented. Even if the molten alloy is a beryllium alloy which is vulnerable to oxidation at the solidification interface, it is prevented from oxidation, and sound solidified ingots are porduced without the degration in cooling efficiency of the molten alloy owing to the formation of metallic oxides.

Title: Hidden-line detecting method
Inventor: SHIBAHARA TERUO
IPC: G06T15/40
Filed: 1987-03-20
Abstract: PURPOSE:To decide whether or not hidden-line processing needs to be performed between respective surfaces of two three-dimensional bodies by finding projection charts when the two three-dimensional bodies are viewed in an optical direction and checking whether or not both projection charges overlap each other prior to the hidden-line processing between the two three-dimensional bodies viewed in the optional direction. CONSTITUTION:Three-dimensional coordinates Aq (Xq, Yq, Zq) of a body 0 in a space are projected first on a screen S to generate coordinate systems AS (XS, YS, ZS) of three axes in a plane. Then the expansion EX of each of the projection charts of plural bodies 0'1 and 0'2 projected on the screen S in the coordinate system AS is determined. In this expansion EX, respective axial widths Xmin-Xmax-Zmin-Zmax of the coordinate systems AS, XS, YS and ZS are detected for each of the plural bodies 0'1 and 0'2 Then whether of not respective axial with of occupation of the plural bodies 0'1 and 0'2 overlap each other is tested for each axis and combinations for which hidden-line processing is not necessary are excluded, so the number of times of the hidden- line processing is reduced and the efficiency of the hidden-line processing is improved eventually.

Title: Semiconductor device and manufacture thereof
Inventor: KANEOKA TATSUNORI
IPC: H01L21/8247
Filed: 1995-03-24
Abstract: PURPOSE: To suppress the dispersion of the erasing rate among bits and reduce the interelectrode leakage current. CONSTITUTION: An interelectrode dielectric film 31 having a lower Si oxide film 16 is formed between a floating electrode 5 and control electrode 6 made of a P-doped polycrystalline Si film. A Si nitride film 17 is formed between the Si oxide film 16 and floating electrode 5. The polycrystalline Si film constituting the floating electrode 5 contains atoms of N. Since the Si nitride film is formed between the floating electrode and Si oxide film, the leakage current between both is suppressed. Since the polycrystalline Si film contains N, the growth of Si crystal grains due to the temp. rising treatment inevitably made in the production process of the device is suppressed to result in that the crystal grains become small. Owing to this, the ends of the floating gates are of a uniform shape whereby the dispersion of the erasing rate among bits is suppressed.

Title: Air conditioner
Inventor: SAKAI TOSHIYUKI
IPC: F24F1/00
Filed: 1987-03-20
Abstract: PURPOSE:To make it possible to improve the flow rate characteristic of the air conditioner and to reduce the noise thereof by providing a heat exchanger comprising a plurality of fin groups, and heat transfer tube group of unequal pitches inserted rectangularly into said fin group, on the upstream side of a cross flow fan. CONSTITUTION:In a heat exchanger 4, at a part 10 where a cross flow fan 5 comes near to the heat exchanger 4, the pitch of heat transfer tube groups 9 is set long and the pitches of the entire groups are made unequal. Therefore, since at the long pitch part 10, the passage area becomes large, the speed of the air flow becomes slow. Furthermore, since the collision of the air flow against the heat transfer tube groups 9, noise caused by the collision is eliminated. Further, since disturbance of the rear flow of the heat transfer tube groups 9 does not occur, the disturbance in the inflowing air is reduced and the noise is also reduced. Furthermore, a ventilation resistance becomes large and the flow rate characteristic is improved.

IPC: G02B21/16
Filed: 1990-03-16
Abstract: PURPOSE:To take a measurement with good efficiency by providing a means for observing an image of fluorescence passed through an absorbing filter which cuts off leaking exciting light in fluorescent light transmitted through a dichroic mirror. CONSTITUTION:When an observation is made by an UV exciting method, an exciting filter 16 and the absorbing filter are replaced with ones for UV excitation and a slide 36 for light/dark field switching is switched to pass ring-shaped light through the slide 36. Then the surface of a sample is irradiated with only ring-shaped dark visual field lighting luminous flux shown by a solid line A and only fluorescent light C generated spherically on the surface of the sample 10 reaches an ocular through an objective 20, the dichroic mirror 18, the absorbing filter 22, and a tube lens 23, so that an observer can observe an observation image by the UV excitation without being affected by the absorption of the objective 20. When the sample is lighted with a light visual field passed through the objective 20 so as to make an observation by an exciting method wherein the absorption of the objective 20 other than the UV range causes no problem, the slide is switched into a state 36B to cut off the illumination light A, thereby lighting the sample brightly with luminous flux B passed through the objective 20.

Title: Combustion control device
Inventor: SAKURAI TOSHIO
IPC: F23N1/00
Filed: 1982-04-20
Abstract: PURPOSE:To prevent blow-out of flame due to a rapid decrease of oil supply rate at the time of transfer of combustion from a strong combustion stage to a weak combustion stage by changing over a burner motor from a strong stage to a weak stage by a method wherein the oil feeding rate of an oil feeding pump is adapted to follow the rotation number of the burner motor. CONSTITUTION:When a contact 10 is opened by changing over the combustion from ''strong'' to ''weak'', a posister 6 is supplied with power through resistors 4 and 5. At this time, the resistance values of the resistors 4 and 5 get higher as time passes making the potential of a PUT1 on the gate side get higher gradually, and when the potential reaches an operation level, the PUT1 turns ON. As the resistance value of the posister 6 increases as the power supply time passes the changing speed of a capacitor 3 gets lower gradually, therefore the socalled ON point of the PUT1 is delayed. The ON-OFF oscillation frequency of thyristors 8 and 13 is decreased as much. That is, the oil feeding rate of the pump 11 is decreased.
