Title: Sample holder for spectrochemical analysis
Inventor: HIRAI SUSUMU
IPC: G01N21/01
Filed: 1984-10-31
Abstract: PURPOSE:To decrease the reflection between surfaces and to decrease interference waves to a negligible level in spectrochemical measurement of a film- shaped sample by constituting a sample holder in such a manner that said holder can turn freely around a shaft perpendicular to stand. CONSTITUTION:The film-shaped sample is first mounted to the prescribed position of the sample holder 3, then the holder 3 is fixed to the position where a pointer 5 indicates the angle theta determined by the refractive index eta of the sample. The film-shaped sample is thus set in such a manner that the main plane thereof maintains the specified angle with the optical path and thereafter the entire part of the device is set to the prescribed position in the sample chamber of a spectrophotometer. The light polarized by passing through a polarizing filter 2 is thereby striken against the sample surface at a desired incident angle, by which the reflection between the surfaces of the sample is eliminated. The spectrum which is substantially free from the pseudo peak occurring from the interference of the reflected wave is thus obtd.

Filed: 1993-09-16
Abstract: PURPOSE:To form an optical semiconductor device which emits light of an arbitrary wavelength or absorbs light of an arbitrary wavelength at a position in a semiconductor wafer, and prepare various kinds of semiconductor integrated circuits. CONSTITUTION:A semiconductor substrate 2 is uniformly coated with a resist 4. A resist pattern, which is mesh-shaped at fine pitches, is formed in an area where a band gap is to be changed on the substrate and the formed pattern is transferred on the substrate by etching. Then, a buffer layer 8, a MQW active layer 10 and a clad layer 12 are formed on the substrate 2 based on an MOVPE method, thereby manufacturing an MQW wafer. In this case, in the mesh-shaped area, a crystal formation rate of each layer is further increased compared with that in an even area. Therefore, the thickness of a well layer of the MQW active layer in this area is increased so that a band gap wavelength may move to a longer wavelength side. An optical semiconductor integrated circuit is available by forming an integrated device on the wafer prepared in this method.

Abstract: PURPOSE:To dispense with a drain oil passage between a high pressure chamber and a valve chest as well as to aim at the miniaturization and compactification of a pump as a whole, by interconnecting the drain oil passage leading out of a rotor rotation shaft to an empty space part between a float control valve chamber and an outer circumferential groove part of a plunger and a reflux port, respectively. CONSTITUTION:A drain oil passage 31 leading out of a rotor rotation shaft 26 is interconnected to an empty space part 38 formed at the outer circumferential groove part between a float control valve chamber 35 and a plunger 36, while the empty space part 38 is interconnected to a reflux port 37. With this constitution, a projecting part, having limited the upper passage of a high pressure chamber 29 so far, can be made smaller or brought into nothing, so that the occurrence of pulsations and noises can be prevented without disturbing a flow of incoming high pressure oil into the valve chamber 35. Also, since the need to pass a drain oil passage through between the high pressure chamber 29 and the float control valve chamber 35 becomes unnecessary, length in the axial direction of a pump is able to make shorter whereby the rotor rotation shaft 26 and a bearing 27 both can be shortened and the miniaturization and compactification of the pump can be promoted as a whole.

Abstract: PURPOSE:To automatically detect the fault of a processing liquid circulation system of an automatic developing machine by providing a branch pipe on said processing liquid circulation system and detecting the current between an electrode disposed in the aperture of the branch pipe and an electrode disposed in a processing tank. CONSTITUTION:A developing soln. is sucked by a pump 3 from the bottom of the developing tank 1 and is passed to the circulation system 2 from which the soln. is circulated to the upper part of the developing tank 1. The branch pipe 7 is provided to the circulation system 2 and the detecting electrode 9 is provided in the aperture 8 thereof in the same position as the liquid surface therein. A contact electrode 10 is provided by immersing the same into the soln. in the developing tank 1. The liquid surface of the branch pipe 7 and the liquid surface of the developing tank 1 are at the same level and the circuit of the detecting electrode 9 and the contact electrode 10 is on and current flows therein, when the pump 3 is static. The soln. in the branch pipe 7 is sucked and the liquid surface is lowered when the pump 3 is driven. The detecting electrode 9 is then detected from the liquid surface and the circuit is turned off so that the current does not flow in the circuit. The liquid surface in the branch pipe 7 does not lower and the circuit is turned on if the pump goes out of order. Whether the circulation system is normal or abnormal is thus automatically detected.

Title: Video signal recording/reproducing system
Inventor: NUMAKURA TOSHIHIKO
IPC: G11B20/02
Filed: 1989-09-06
Abstract: PURPOSE:To improve the reliability of a reproduced video signal which is suitable for an image monitor but is unsuitable for other recording systems by simply adding a dubbing disablement identification(ID) signal to a recording system, and in a reproducing system, deforming a vertical or horizontal blanking period part to form a reproduced video signal. CONSTITUTION:In the recording system, an input video signal to which a dubbing disablement ID signal is added without deforming itself is recorded in a recording medium. When the video signal to which the dubbing disablement ID signal is added is recorded in the recording medium and applied to the reproducing system, at least the vertical or horizontal blanking period part of the video signal read out from the recording medium or a signal included in the period part is made different from the state recorded in the recording medium to form a reproduced video signal. Although such kind of a reproduced video signal is suitable for the image monitor but is unsuitable for the recording system of another video signal recording/reproducing system, a reproduced signal from the reproducing system can be formed based upon the video signal read out from the recording medium under the comparatively large degree of freedom.

Title: Memory device
Inventor: TAKISHIMA TORU
IPC: G06F12/16
Filed: 1985-10-18
Abstract: PURPOSE:To easily diagnose the instruction retry function of a system controller by producing selectively the fixed and intermittent errors based on the output signal of an intermittent error setting register. CONSTITUTION:When a control signal 11 is sent to a control circuit 4 from a system controller, the circuit 4 gives an instruction for a diagnosis writing action. The diagnosis data 7 and 9 are sent to an intermittent error setting register 1 and a pseudo trouble register 2 later than the signal 11 by a clock. The logic 1 is set to both registers 1 and 2. The output signals 8 and 10 of registers 1 and 2 and an action instructing signal 12 are supplied to an AND gate 3. Thus the AND of said signals sets a pseudo trouble resetting signal 13 at logic 1 and both registers 1 and 2 are reset. As a result, it seems that not only a fixed error but an intermittent error are produced to the system controller.
