IPC: F23N5/00
Filed: 1981-04-20
Abstract: PURPOSE:To reduce heat loss and generation of black smoke by a method wherein the total sum of the heat losses of exhaust gas as well as unburnt exhaust gas is computed from the concentrations of O2, CO and the like in the exhaust gas of a combustion furnace such as a boiler or the like and the amount of supplying air is controlled so as to reduce this total sum. CONSTITUTION:Master signals such as the set temperature of the heating furnace 1 or the like are inputted into a fuel control circuit 20 to effect the fuel control through a fuel indicating and controlling meter 30. An air amount setter 9 inputs a logical air amount into a high signal selector 8 and an operating unit 6 and controls an air flow valve 32 through an air control circuit 10 and an air indicating and controlling meter 11. On the other hand, an exhaust gas temperature in a a fue 2 is detected by a senser 22 while the concentrations of O2 and CO therein are detected by the sensers 4, 5, and all of them are inputted into the operating unit 6 respectively. The operating unit 6 computes the total sum of the heat losses due to excess air and the unburnt matters and sets the amount of the supplying air so as to reduce this total sum thereby controlling the air flow controlling valve 32. Thus, the heat losses and the generation of black smoke may be reduced.

SOLUTION: The incident beam of a laser 1 via a light quantity adjuster 2 and a mirror 3 is splitted into a transmitted light beam and a reflected light beam by a beam splitter 4 consisting of a polarization branching element. The reflected light beam A is traveled via an optical super-high resolution element 5-1, a mirror 3, an optical modulation/polarization unit 7-1 and a translucent mirror 8, while the transmitted light beam B via an optical super-high resolution element 5-2, a mirror 3 is given a phase difference of 1/2-wavelength by a πphase shift plate 6 and is synthesized with the beam A. At this time, one spot of the beam B and the beam A cancel out to become almost one beam only. Consequently, by utilizing the obtained minute spot, the optical disk substrate having small recording marks can be formed, and the optical head of the minute spot can also be obtained.

Title: Keyboard circuit
Inventor: FUJIZU TADASHI
IPC: H03M11/00
Filed: 1986-03-20
Abstract: PURPOSE:To reduce the number of parts of a switching circuit and the power consumption and to scan contacts at high speed by adding a turn-on contact detecting circuit and a parallel/serial transforming circuit to a key matrix to reduce the number of interface signals. CONSTITUTION:This keyboard circuit consists of a key matrix 2 where plural key switches 1 are arranged in a matrix, a turn-on contact detecting circuit 12 which has two kinds of threshold level and consists of plural comparator amplifying circuits, and a parallel/serial contransforming circuit 13 which transforms the parallel output of the turn-on contact detecting circuit 12 to one serial data and generates a control signal which indicates it to the reception side that the duration of the turn-on state of a depressed contact can be discriminated and serial data can be received. Since the turn-on contact detecting circuit 12 and the parallel/serial transforming circuit 13 are added to the key matrix 2, the serial data signal and the control signal are enough for interface to each control circuit system even when one key matrix 2 is connected to two control circuits independent of each other of a telephone type terminal equipment or the like by switching and is controlled, and thus, the number of interface signals is reduced.

Title: Driver circuit
Inventor: MASUDA KOUJI
IPC: H03K19/018
Filed: 1978-05-24
Abstract: PURPOSE:To reduce greatly power consumption in a stationary state and to charge and discharge a large capacitive load at a high speed by adding a generating circuit for a transient charge-discharge current which shorten the charge-discharge time of the load. CONSTITUTION:Once transistor Tr100 is applied with an input signal low in logic level, Tr100 is cut off and Tr 102 and 104 are in conduction to start charging from the output terminal to the load. However, since resistance 130 has an extremely high value bacause of low power consumption, generating a transient current from Tr 108 via resistances 136 and 138 increases the base current of Tr 102 momentarily, allowing charging the load to end in a short time. On the other hand,  terminal N1 becomes high in level and when Tr 100 starts conducting, Tr 108 is  cut off, so that large currents will flow to the base of Tr 106 via Trs 108 and 100.  As a result, Tr 106 discharges the load capacity suddenly. After the discharge,  the input of terminal N2 is made low in logic level to cut off Tr 108, so that the  power consumption can be suppressed low.

Filed: 1990-03-13
Abstract: PURPOSE:To obtain the optical switch which is small in size and low in cost by providing a switching means switching two groups of N-multiple circuits mutually in units of N optical paths which are different or equal in optical path direction. CONSTITUTION:A prism 2 is provided as the switching means which converts couples of double circuits, i.e. four optical paths in units of two optical paths differing in optical path direction without changing their optical path directions, and the prism 2 is moved to turn off the optical switch 1 when a prism state is interposed in none of the optical paths 3-6 or turns on the optical switch 1 when the prism state is present. When the optical switch 1 enters the ON state, the couples of double circuits are switched mutually in the units of the optical paths 2 and 6, and 5 and 6 differing in optical path direction. Thus, the switching is performed in the units of two optical paths, so the switching means can be composed of the single prism 2, and the optical switch is reduced in size, simplified in constitution, and reduced in cost.

Inventor: SUGIYAMA SUNAO
IPC: G02F1/31
Filed: 1986-03-19
Abstract: PURPOSE:To provide a titled device which is smaller in size, higher in reliability, mass-produceable, free from adjustment of bond and lower in loss by impressing a reverse bias voltage relative to a p-n junction to an electrode to increase the refractive index near an optical waveguide layer, thereby selectively forming optical waveguides. CONSTITUTION:The recombination of a carrier arises in an n-InGaAsP active layer and laser oscillation arises in a resonator formed of the Miller face on the side face of the active layer when electric current is implanted to the electrode in the upper part of a laser part 10. The laser output light from the laser part 10 passes a groove 40 and is guided to the n-InGaAsP waveguide layer 52 of an optical switch part 20. A depletion layer spreads to the part corresponding to the electrode shape near the p-n junction 60 and the refractive index is increased by the decrease of the carrier concn. when the reverse bias voltage-V1 is impressed to the electrode 21 by shifting a switch SW1 upward. The optical waveguide is, therefore, selectively formed under the electrode 21.
