IPC: G01S17/36
Filed: 1985-05-29
Abstract: PURPOSE:To compensate variation in the optical path length of an optical fiber and variation in the phase characteristics of a light emitting and a photodetecting part and to measure the length of an optical path with high precision by performing control arithmetic processing on the basis of a delay time in an atmosphere to be measured and measuring the length of the optical path in the atmosphere. CONSTITUTION:A light emitting means 21 and photodetecting means are connected to one terminal of a directional coupler 31 through the optical fiber and a mirror 33 and a light projecting and photodetecting means 34 are connected to the other terminal; and a light emitting means 22 and a photodetecting means 23 are connected to one terminal of the directional coupler 32 and a mirror 35 and the means 34 are connected to the other terminal. Then, the means 21 is driven to measure the phase difference between a light wave reaching the means 24 and a light wave reaching the means 23 and the means 22 is also driven to measure the phase difference between the light wave reaching the means 23 and the light wave reaching the means 24 by a phase difference measuring means 25 respectively. An optical path length arithmetic processing means 26 calculates the length of the optical path in the atmosphere to be measured on the basis of both phase differences. Consequently, variation in the optical path length of the optical fiber which couples a main measuring instrument body and a projecting and photodetection optical system and variation in phase between the light emitting part and photodetection part are compensated to measure the optical path length precisely.

Abstract: PURPOSE:To obtain an AlN substrate which has excellent bond properties without reducing heat conductivity by adding metallizing assistant powder comprising W or Mo metal powder or its carbonate or an oxide and forming a green sheet and then calcining said green sheet. CONSTITUTION:1 to 5 part weight W powder, which serves as a metallized assistant, is mixed with 100 part weight AlN powder to which 7wt.% oxidative yttrium is added while 10 pts.wt. polyvinyl butyral is mixed there as a binder and 10 pts.wt. dibutyl phthalate is mixed as a plasticizer and 50 pts.wt. ethanol is mixed as a dispersant, thereby producing a green sheet for the surface layer. The green sheet 1 for the surface layer which contains the metallizing assistant is placed on the AlN green sheet layer 2 and integrated into one piece under the application of pressure. After the application of pressure, the green sheet is calcined in the N2 gas stream so that an AlN substrate may be formed. Since this AlN substrate maintains a high heat conductivity of around 200W/mk, it is very useful as a substrate for an integration circuit.

Title: Fixing unit using radiant light source
Inventor: OOTA SHIYUUICHI
IPC: G05D23/19
Filed: 1979-09-11
Abstract: PURPOSE: To maintain the fixing temperature at nearly a fixed level regardless of fluctuation of the power supply voltage, by giving a control to the time of conduction each time to the high- luminance radiant light source in accordance with the voltage fluctuation of the AC power source.  
     CONSTITUTION: When the DC voltage corresponding to the voltage of the AC power source A emerges at the capacitor 4c of the voltage compensating circuit 4, the output of the operational amplifier 4d produces the voltage having a level which reversely corresponds to the power supply voltage. As a result, the IC element 4f generates the pulse having a duration which is adversely proportional to the power supply voltage. The element 4f incorporates a unified structure of the integral network which produces the saw-tooth type wave according to the feed of the recording paper by a fixed length after receiving the supply of the recording paper feed synchronous pulse via the inverter 4c plus the comparator which detects the coincidence between the voltage of the saw-tooth type wave and the output voltage of the amplifier 4d. With this pulse, the 2-way thyristor 2 is triggered via the gate control circuit 5 and the zero-phase detecting circuit 3, and thus the time of conduction is controlled each time in accordance with the power supply voltage for the halogen lamp 1 which forms the high radiant light source. Accordingly, the fixing temperature can be maintained nearly at a fixed level for the fixing unit and regardless of fluctuation of the power supply voltage.

Title: X-ray mask
Inventor: DEGUCHI KIMIKICHI
IPC: G03F1/22
Filed: 1991-04-22
Abstract: PURPOSE:To improve an effective contrast by reversely utilizing changes in an X-ray diffraction in proximity exposure of a fine pattern and an effective contrast due to influence of mutual interference. CONSTITUTION:An X-ray transmitted through a membrane 2 is diffracted in response to a gap between a mask 3 and a wafer. X-rays transmitted through absorber layers 4, 5 are attenuated in intensities and simultaneously varied in phases. Further, these X-rays are interference with each other. Affecting ranges of the diffraction and the interference depend upon the wavelengths of the X-rays and the gap, and a range in which the influence is largest is up to more or less 0.2mum from a pattern edge. Accordingly, the smaller than pattern size is, the larger the results of the diffraction of the X-rays and the diffraction become, and an intensity distribution of the transmitted X-ray is varied. When this effect is reversely utilized and the thickness of the absorber layer of the fine pattern region is so determined that the X-ray intensity distribution becomes optimum, an effective contract in a pattern of a small size is improved.

Title: Semiconductor device
Inventor: HIUGA TSUTAE
IPC: H03K3/353
Filed: 1989-05-10
Abstract: PURPOSE:To reduce the chip size by leading the connection point between two N-channel transistors(TR) to a high potential VDD when the output at the connection point between P-channel and N-channel TRs has the high potential VDD and turning off the point when the output has a low potential VSS. CONSTITUTION:When the input voltage of an input terminal 11 varies from the VSS to the VDD, the inverted voltage of this circuit is close to the VDD side as compared with the inverted voltage of the inverter consisting of the P-channel TR 15 and N-channel TRs 16 and 17. When the voltage varies from the VDD to the VSS, on the other hand, the voltage is the inverted voltage of the P-channel TR 15 and N-channel TRs 16 and 17. Consequently, the inverted voltage can be made different according to whether the input voltage of the input terminal 11 varies from the VSS to the VDD or vice versa. Consequently, a Schmitt trigger circuit can be composed of a small number of elements.
