IPC: G02B6/30
Filed: 1992-02-26
Abstract: PURPOSE:To assemble a part main body without angular deviation in the metallic block of a waveguide circuit parts and waveguide type optical circuit parts such as input/output fiber parts. CONSTITUTION:The metallic block 12 of the waveguide circuit part 10A is constituted of a reverse L-shaped upper block part 18 which is stuck and fixed on the upper face and one side face of a chip 16, and an L-shaped lower block part 20 which is stuck and fixed on the lower surface and the other side surface of the chip 16. The edges 18a and 20a of the upper and the lower block parts 18 and 20 are opposed to each other through gaps 22 and 24. Therefore, the chip 16 is stuck and fixed without the gap on the metallic block 12, the angular deviation is not caused between both of them. They are arranged and connected to other circuit parts.

Filed: 1981-05-15
Abstract: PURPOSE:To ensure the accurate setting for the operation mode of a copying machine, by displaying an image information data of an original which is obtained from a preliminary scan for the automatic setting of the operation mode of the copying machine and utilizing the information data for the manual setting. CONSTITUTION:When a preliminary scan is given to an original 3 via an exposure lamp 8, the light of an exposed image is received at a photosensor 15. Then the original image information data is supplied to a control circuit CC via a switching circuit 21, a peak holding circuit 22 and an A/D converter 22. Thus the control data of an erasing lamp 13, the light volume control data of the lamp 8 for copying, and others are decided at an arithmetic part of the circuit CC and according to the size of an original. Then the operation mode of a copying machine is automatically set according to the original. On the other hand, in the manual mode, the original image information data obtained via a converter 23 and the circuit CC and in the preliminary scan mode is displayed by a display device corresponding to an operation part 71. As a result, the accurate manual setting is possible in the copying operation mode.

Title: Carry circuit for data processor
Inventor: PETER J KLIM
IPC: G06F7/50
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a carry circuit in a data processor capable of outputting a signal based on the evaluation of an input signal. SOLUTION: The circuit 300 has many transistors(TRs) constituted so as to trigger an output signal by the trigering combination of an input signal. The circuit 300 is also provided with discharge TRs and a signal for switching the node of the circuit 300 to a discharging state is supplied. Since the node should be discharged to a fixed level to trigger an output signal, the node is discharged by activating a signal to be supplied to the discharge TRs once charging the node up to the fixed level or more, so that the evaluation time of the circuit 300 is shortened.

IPC: G03D9/00
Filed: 1991-04-05
Abstract: PURPOSE:To improve operabilities by calculating remaining developing time from set developing time and counted time and displaying the remaining developing time in real time. CONSTITUTION:A call is made at every second, and subtraction is executed on a timer T1, to display the remaining developing time corresponding to the lapse of time on a zoom/developing time display part 508. Then, whether the timer has zero or not, is checked (4711), and when the timer T1 does not have zero, that is, development is not finished, on the timer T1, the subtraction by a second is executed (4712), and the subtracted value is displayed on the zoom/ developing time display part 508 (4713). At this time, the display of the zoom/ developing time display time 508 is changed over to a developing time display. When the timer T1 has zero, that is, the developing time is finished, buzzer warning is given (4714), and the developing time displayed on the developing time display part 508, at present, is changed over to a zoom display (4715). Thus, an operator can obtain the remaining developing time in real time.

Title: Bipolar logic circuit
Inventor: TAKI YOICHIRO
IPC: H03K19/088
Filed: 1987-03-26
Abstract: PURPOSE:To increase noise margins and to prevent the titled circuit from generating malfunction due to the influence of noise by inserting a serial connection of a resistor with a Schottky barrier diode(SBD) between the base of a 3rd bipolar transistor(BTR) and a 2nd constant potential point. CONSTITUTION:The serial connection of the resistor 13 with the SBD 14 is inserted between the base of the npn transistor(TR) 3 connected to a SBD and the 2nd constant potential point GND. When both logic inputs A, B are H levels, an pnp TR 1a is turned off and an npn TR 2 connected to a SBD is turned on, so that current flows from the 1st constant potential point VCC to the 2nd constant potential point GND through a resistor 7, the TR 2, a resistor 13, and the SBD 14. Thereby, the npn TRs 3, 4 are turned on and a logic output Y is turned to an 'H' level. Consequently, logic amplitude  V at a base potential VB is increased and the noise margin is also expanded in accordance with the increase of the amplitude  V.

Title: Electromechanic optical modulator
Inventor: TOKUHARA MICHIHIRO
IPC: G02B26/10
Filed: 1985-04-09
Abstract: PURPOSE:To suppress unnecessary reflected light and scattered light and to prevent deterioration in S/N ratio by making reflecting surfaces other than a mirror rocking part low in reflection factor than the mirror rocking part. CONSTITUTION:The mirror rocking part 13 is a reflecting part which contributes to signal light and has a 87-95% reflection factor. The reflection factor of this part is preferably high so as to increase the intensity of the signal light, but a mirror surface part 15 is preferably low in reflection factor because it is the place where unnecessary reflected light, scattered light, and diffracted light are generated. For the purpose, the mirror surface part 15 and part of an end part (a) are coated with a light absorptive material or low reflective material to decrease their surface reflection factor. Consequently, unnecessary light and scattered light are reduced and the S/N ratio of the signal is increased.

Abstract: PROBLEM TO BE SOLVED: To obtain a means for forming self-aligned contact holes by dry etching a BPSG film/PSG film anisotropically and selectively to a silicon oxide film, using a compd. gas contg. C, F and/or H mixed with CH2 F2 . SOLUTION: Using silicone oxide films 4, 7 as an etching stopper, a BPSG film is anisotropically dry etched to form contact holes 10, using an etching gas composed of a compd. gas contg. C, F and/or H mixed with CH2 F2 . Even if the contact holes are larger than the electrode interconnection line spacing, they can be formed, without short-circuiting with the electrode interconnection. Thus it is possible to reserve an allowance for forming the contact holes by the lithography even if the electrode interconnection line spacing of a semiconductor device is very small.

Filed: 1988-03-28
Abstract: PURPOSE:To easily manufacture a product hardly causing the occurrence of powdering at the time of working, such as press forming, by subjecting a steel strip plated by dipping into a molten Zn bath containing specific amounts of Al and Pb to heating in an open-coil state under specific conditions. CONSTITUTION:A steel sheet after pretreatment is dipped into a molten Zn bath containing, by weight, 0.05-0.3% Al and <=0.2% Pb to undergo plating by 30-90g/m<2> coating weight per side. Subsequently, this steel strip is rewound into an open coil state and then heated in a batch-type annealing furnace of nonoxidizing or reducing atmosphere at 320-419.5 deg.C (the melting point of Zn) for 1-50hr, by which the plating layer is alloyed. When Al content in the Zn bath exceeds 0.3%, the necessity of raising the heating temp. of the steel strip to a temp. beyond 419.5 deg.C arises and powdering resistance at the time of working is deteriorated. Further, when Pb content in the plating bath exceeds 0.2%, powdering resistance at the time of working is deteriorated.
