Title: Reception circuit
Inventor: FURUYA SEIICHI
IPC: H04L25/40
Filed: 1980-07-24
Abstract: PURPOSE:To increase the noise-proof performance and to make easy the multidrop connection with high input impedance, by detecting and outputting the difference between a noninverting and an inverting input inputted to a comparator, in a reception circuit using a pulse transformer. CONSTITUTION:If noise is applied to the primary side of a pulse transformer 11, a pulse in which a voltage is uniformly increases or decreases by taking a center tap 13 as the reference is appeared at terminals 17, 20 of the secondary winding 14. A voltage at the terminal 17 is divided at resistors 18, 19, a voltage at the terminal 20 is devided with resistors 21, 22, and a voltage between terminals 27, 28 is applied to a noninverting input A and an inverting input B of a comparator 23. In this case, since the changing part and the direction of the noise applied to the inputs A, B is equal, the voltage difference is the same as the state without noise.

In such a way, the input without dead point can be executed. By using a nonmagnetic thin plate 4, the suitable space of the upper and lower resistance sheets 5 and 5' can be easily set, and the finger input can be executed.

Filed: 1991-04-05
Abstract: PURPOSE:To stably form a thin developer layer on a developing sleeve and to obtain a good image by arranging a developing magnetic roll and a developer supplying magnetic roll so that the same magnetic poles of the rolls may face oppositely and making a distance between magnetic poles on the developing magnetic roll adjacent to two opposed magnetic poles shorter than a distance between magnetic poles on the developer supplying magnetic roll. CONSTITUTION:The N pole of the developer supplying magnetic roll 3 is arranged opposite to an N pole; one of the magnetic pole of the developing magnetic roll 2. Then, both distances to two S poles adjacent to the aforesaid magnetic pole on the developing magnetic roll 2 are made shorter than that on the developer supplying magnetic roll 3. By arranging the same poles to face oppositely, the layer thickness of the developer moving from the developer supplying magnetic roll 3 to the developing magnetic roll 2 is controlled and uniformized by a repulsive force between the magnetic poles. A caryying state of the developer on the developing magnetic roll 2 is more stabilized and uniformized than the carrying state of the developer on the developer transfer area on the developer supplying magnetic roll 3 by the difference of the distances between the magnetic poles on the rolls 2 and 3.

Title: Engine speed control for internal combustion engine
Inventor: YASUOKA AKIMASA
IPC: F02D41/00
Filed: 1985-05-14
Abstract: PURPOSE:To suppress the variation of engine speed by calculating the learned value on the basis of the deviation of the engine speed from an aimed idle engine speed and controlling an intake control valve according to the sum of the warming signal corresponding to the engine temperature and the learned value when the engine is not in idling state. CONSTITUTION:A control valve 30 which includes a solenoid 16 and controls the opening area in proportion to the electric conduction quantity is installed into a bypass passage 31 installed into an intake passage 33 so as to make a detour around a throttle valve 32, and the engine speed in idling is controlled by controlling said control valve 30. In other words, when an engine is in idling state, the control valve 30 is feedback-controlled by an electronic controller 40 so that the engine speed Ne accords with an aimed idle engine speed Nref. In this case, when the engine temperature is over a prescribed value, the learned value is calculated on the basis of the deviation of Ne from Nref. In nonidling state, the control signal for the control valve 30 is generated according to the sum of the warming signal set according to the engine temperature and the learned value.

Title: Distributor for sludge
Inventor: METSUGI MASATAKE
IPC: B01J4/00
Filed: 1979-08-09
Abstract: PURPOSE:To miniaturize devices themselves, particularly, them in the height direction, by a method wherein natural flowing-down distances to sludge concentrating devices from distributing pipes connected to a single sludge feed pipe are decreased at a necessary minimum limit. CONSTITUTION:A plurality of branch pipes 3a, 4a are connected to the single sludge feed pipe 2, and the dimensions of the inner diameters of the branch pipes are formed at comparatively large value while weirs with V-shaped cut portions 7a are made up to the horizontal portions 5 of each branch pipe 3a, 4a connected to a plurality of centrifugal sludge concentrating devices 9, 10 to form the surfaces of sludge. Since the dimensions of the branch pipes 3a, 4a formed at comparatively large value and the upper portions are opened to the atmosphere, the surfaces of the sludge in the horizontal portions 5 become similar, and the quantities of the sludge flowing down become the same. Thus, there is no necessity for ensuring the heads of the flowing-down of the sludge, sludge distributors 1 can be arranged at the same height as the concentrating devices 9, 10, and the devices can be miniaturized.

Title: Distributed feedback semiconductor laser
Inventor: ABE YUJI
IPC: H01S5/00
Filed: 1989-04-20
Abstract: PURPOSE:To provide a narrow spectral line width characteristic where a mode is stabilized upon high output power by changing a coupling constant in the direction of a resonator by changing the pitch of a diffraction grating. CONSTITUTION:There are successively grown on an n-InP substrate 1 an n- InGaAsP active layer 2, a P-InGaAsP diffraction grating layer 3, a P-InP capping layer 4 (thickness=t). Then, opposite ends of the layer 4 are etched into a film thickness satisfying s<t. The region etched as such is called a region I, and a region not yet etched is called a region II. Further etching is performed such that the depth is (t) or more, to form a distributed feedback diffraction grating 5. Thereupon, since the film thicknesses (s) are different in the regions I and II, the pitch of the grating 5 can be changed even with the etching depth kept unchanged. Since a coupling constant is made smaller near the center where light intensity is high, mode instability due to axial, spatial hole burning can be restricted even upon high output operation.

Title: Optical thyristor

IPC: H01L29/74
Filed: 1980-07-25
Abstract: PURPOSE:To improve optical sensitivity without sacrificing dV/dt resisting quantity and di/dt resisting quantity by prolonging the carrier life time of the second base layer, the first base layer and the first emitter layer just under a light receiving section. CONSTITUTION:The second base layer 3 is exposed at the center of the light  receiving section 9 with a radius (r) formed to a cathode electrode 6 and the second emitter layer 4 on an outer circumference of the layer 3. Au is diffused to a PNP laminating section 10 of the second base layer 3, the first base layer 1 and the first emitter layer 2 just under an exposing section 3a of the second base layer, using a SiO2 film as a mask lest a life time killer should enter, and an oblique line section in which life time is short is shaped. When light 7 emitted from a light guide 8 is irradiated to the light receiving section 9, since a current amplification factor of the PNP laminating section 10 to which Au is not diffused is large, the optical sensitivity is high, and the thyristor can ignite with the small quantity of light.
