Title: Production of ammonia using metal hydride as hydrogen source
Inventor: ADACHI KINYA
IPC: C01C1/04
Filed: 1999-03-04
Abstract: PROBLEM TO BE SOLVED: To synthesize ammonia under mild conditions by supplying hydrogen in the form of atoms of high activity to a reaction chamber side from a gaseous hydrogen atmosphere and reacting the same with the active nitrogen dissociatively adsorbed on a catalyst deposited on a reaction chamber side diaphragm surface by using a metal hydride as a hydrogen permeable membrane. SOLUTION: The hydrogen in the form of atom of high activity on the reaction chamber side is stationarily supplied from the gaseous hydrogen atmosphere (1.5 atm) on the one side of the diaphragm by using the metal hydride as the hydrogen permeable membrane (diaphragm). The Ru/MnO2 catalyst 2 is deposited on the reaction chamber side diaphragm surface. The active nitrogen subjected to the dissociation adsorption by passing the gaseous nitrogen of ordinary pressure on this Ru/MnO2 catalyst 2 and the hydrogen in the form of atom supplied from the diaphragm are reacted to synthesize the ammonia. The ammonia synthesis is possible even if the reaction temperature is low temperature near room temperature. The ammonia may be synthesized under the reaction conditions milder than the method of around 500 deg.C and about 200 atm in pressure which is heretofore industrially practiced.  There is no need for a specific apparatus for high pressure resistance and high temperature.

Title: Fourier transform type interference spectroscope
Inventor: UEDA TOSHITSUGU
IPC: G01J3/45
Filed: 1989-03-09
Abstract: PURPOSE:To enable fast measurement by selectively detecting a voltage which is proportional to an intensity of an interference fringe which coincides with a pitch of a space filter within the interference fringe corresponding to a wavelength of light formed on an image sensor with the rotation of a mirror on one optical path to measure a spectrum. CONSTITUTION:By presenting an interference corresponding to an inclined surface theta of a rotary mirror 2, an interference fringe is formed on an image sensor 10 having a space filter characteristic. The sensor 10 is made up of an array of photodiodes PD1, PD2... and PDn which are connected every other one in two groups. For example, when light Pin to be measured is a single spectral light with a wavelength lambda, a pitch (d) of the fringe develops an interference fringe as given by d=lambda/sintheta and a voltage is outputted after a signal processing as proportional to an intensity of light inputted corresponding to a wavelength theta at which the pitch (d) of the interference fringe is equal to a pitch P of a space filter 10. Thus, a spectrum of light inputted can be measured from a graph obtained by plotting an output from a signal processing section 20.

Title: Semiconductor integrated circuit
Inventor: SEGAWA MAKOTO
IPC: G11C8/06
Filed: 1981-04-16
Abstract: PURPOSE: To reduce power consumption even in an active state and to speed up operation by employing MOS structure equipped with a buffer circuit.  
     CONSTITUTION: Depletion type MOS transistors (TR)31W33, and E type MOSTRs 34W36 constitute E/D type inverters (INV)1W3, and MOSTRs 40 and 41 constitute an INV4; and MOSTRs 42 and 43 constitute an INV5, and MOSTRs 45 and 46 constitute an INV6. Further, MOSTRs 47 and 48 constitute a push- pull type output stage INV7. Furthermore, E type MOSTRs 50 and 51 inputting a signal CS' as a gate input are inserted between the output terminal of the INV2 and a Vss, and that of the INV3 and the Vss. Consequently, few steady state currents flow in the output-stage INVs 5 and 7 and steady state currents in the INVs 1W6 driving the INVs 5 and 7 are reduced. Thus, the power consumption of the whole circuit in an active state is reduced and the load capacity of each inverter is also reduced to achieve high-speed operation.

Title: Semiconductor device for voltage control type current source
Inventor: KAWAHITO SHOJI
IPC: H01L27/07
Filed: 1986-03-14
Abstract: PURPOSE:To simplify a computing circuit and to reduce the occupying area of a semiconductor device by forming a base-grounded junction type transistor in a CMOS planar process, and further integrating the collector of the transistor with the source of an MOS transistor to perform a voltage control current source. CONSTITUTION:A lateral pnp transistor is formed together with an MOS transistor in a normal CMOS planar process, and a voltage control current source is formed by a structure that the collector 1 of the pnp transistor and the source of the p-channel MOS transistor are integrated. When a bipolar transistor is generally formed together with the MOS process, it is necessary to separate between elements in the bipolar transistor, but since the pnp transistor is used only as a constant-current source and the base 2 can be used commonly with the substrate of the p-type MOS, the separation between the elements is not necessary to reduce its occupying area. Since a threshold detector using such a voltage control current source has excellent high speed and compactness as compared with that only with the MOS device, the performance and the integrating density of a digital system with VLSI can further be enhanced in this computing circuit.

Title: Optical sensor
Inventor: YANO EIZOU
IPC: G01J1/44
Filed: 1980-04-30
Abstract: PURPOSE:To enable the amount of light to be sensed stably by providing a constitution wherein a hysteresis width can be readily obtained at the input side of a comparator. CONSTITUTION:When the output voltage from a light receiving circuit 1 becomes larger than a reference voltage Vref, the output from an operation amplifier OP2 approximately becomes the voltage (H) of power source Vcc. The voltage drives a transistor Tr1 via resistor R13 and turned on said transistor Tr1. As a result, when the output of the operational amplifier OP2 approximately becomes the voltage H of the power source Vcc, the reference voltage Vref becomes low, and the hysteresis is yielded. When the output voltage of the light receiving circuit 1 becomes lower than the reference voltage Vref, the output of the operation amplifier OP2 becomes L, and the transistor Tr1 is turned OFF again. Since the state of the output of the operation amplifier is maintained in response to the width of the hysteresis, the circuit operates stably.
