Title: Reproducing type frequency divider
Inventor: ICHINO HARUHIKO
IPC: H03K23/00
Filed: 1987-09-22
Abstract: PURPOSE:To attain higher speed operation by adopting the peaking technology to a parallel feedback amplifier comprising an inserted emitter follower transistor(TR) so as to attain broad band frequency characteristic to the open loop gain of a reproduction type frequency divider. CONSTITUTION:Emitter follower TRs Q13, Q14 are inserted to a feedback part of a parallel feedback amplifier PFA. A base-emitter capacitor CBE and a base- collector capacitor CBC of the TRs Q13, Q14 act like the peaking capacitance, the gain frequency characteristic of the mixer is improved at higher frequencies, resulting in improving the frequency characteristic of the open loop gain. Even if the feedback quantity is increased by decreasing feedback resistors R3, R4, the base-collector voltage of TRs Q7, Q8 of the parallel feedback amplifier is ensured to be a minimum limit VBE. Thus, the broad band characteristic is attained for the amplifier. Moreover, the input sensitivity is improved by 1.5-2.0 times and the operating frequency band is moved toward high frequen cies by nearly 15%.

Title: Hydraulic control device for automatic transmission
Inventor: MATSUMOTO AKIO
IPC: F16H61/10
Filed: 1987-09-22
Abstract: PURPOSE:To simplify the structure by providing a directional control valve adapted to communicate a supply oil path with a pressure discharge path when the supply oil pressure is less than a designated value in an oil path between a pressure regulating valve for controlling oil pressure supplied to a friction element and the friction element. CONSTITUTION:3-4 PCV 50 is constructed so that when output oil pressure is controlled by pilot pressure controlled by the second duty solenoid 46 to shift 3-4 clutch 27 from the second speed to the third speed in the open state, oil pressure is gradually increased and passed through a directional control valve 220 to be sent to the 3-4 clutch 27, whereby the clutch is connected without a speed change shock. On the other band, at the time of shifting from the third speed to the second speed, though output oil pressure of the 3-4 PCV 50 is decreased, it can be kept from being zero by a fail-safe spring 205 or the like, and when it becomes less than a designated value, the directional control valve 220 is switched by a spring 228 to open a drain port and let clutch pressure escape, whereby the clutch 27 is opened. By this arrangement, it is not necessary to provide a shift valve controlled according to operating condition by control means, so that the structure be simplified.

The treated film is used as the substrate and the ferromagnetic alloy layer 2 consisting of a Co-Cr alloy, etc. is first formed on one or both surfaces (both surfaces in the figure) by orienting the axis of easy magnetization in the direction perpendicular to the layer plane by a sputtering method, etc. A protective film 3 consisting of Al2O3, etc., and a lubricating layer 4 consisting of fluorocarbon, etc. are then provided on the layer 2. The residual solvent of the substrate 1 is decreased and the weakened adhesive strength as a result of the bleeding of the solvent onto the surface by the effect of the heat in the stage of forming the magnetic layer 2 is obviated. The long-life recording medium which obviates the exfoliation of the layer 2 during use is thus obtd.

Abstract: PURPOSE:To always and normally transmit data by switching the data transmitted from a prestage equipment and the data in a present transmitter, timing- regenerating the output and a frame pulse by means of a clock and outputting them to an equipment in a subsequent stage. CONSTITUTION:A receiver 1 outputs a clock (a) generated in a clock generation circuit 3 and the frame pulse (b) to a transmitter 2a.

The switching circuit 7 changes over the data from a previous stage in accordance with the timing with the data of the its own equipment and outputs it to a timing reproduction circuit 8. The timing reproduction circuit 8 timing-reproduces the frame pulse (b) and the output of the switching circuit 7 in accordance with the clock (a), and outputs them to a transmitter 2b in the subsequent stage. Thus, data is always and normally transmitted regardless of the distance between the receiver 1 and the transmitter 2 or the number of the transmitters.

IPC: G01N27/409
Filed: 1987-09-25
Abstract: PURPOSE:To enable the stable control of an air-fuel ratio to be close to a theoretical air-fuel ratio only by integral control, by detecting an electromotive force generated in accordance with an oxygen concentration difference, between an electrode on the side of a surface made to contact with air and an electrode on the side of a surface made to contact with an exhaust of an engine. CONSTITUTION:Inside and outside electrodes 22 and 23 made of Pt respectively are formed in parts of the inner and outer surfaces of a ceramic tube 21 whose main component is ZrO2 which is a solid electrolyte having oxygen ion conductivity, and on the outer surface of the ceramic tube 21, a Pt catalyst layer 31 is formed by evaporation of Pt only on the fore end part thereof. An Rh catalyst layer 32 containing Rh as a main component is laid on the outer surface of the Pt catalyst layer 31, and moreover a protective layer 33 protecting the catalyst layers 31 and 32 is formed on the outer surface of the layer 32. By this constitution, the quantity of adsorbing points existing on the surface of the catalyst layer 31 is reduced sharply, a function of facilitating reactions of CO and HC with O<-> ions on the surface of the catalyst layer 31 is suppressed to a large extent, and a characteristic of an output value varying gently to and from the concentration of oxygen in an exhausting corresponding to a theoretical air-fuel ratio as boundary, is obtained. Accordingly, the air-fuel ratio obtained from the air-fuel ratio control using an oxygen sensor can be made stable in close vicinity to the target theoretical air-fuel ratio.

Title: Pulse code modulation signal reproducer
Inventor: YOHANESU BERUNARUDASU HORUSUTE
IPC: H04N9/88
Filed: 1987-09-25
Abstract: An apparatus for reproducing a pulse-code-modulated signal comprises error-correction means (3) for correcting errors in one or more of the data words forming the pcm signal. When the error-correction means are no longer capable of correcting errors in the pcm signal, they produce error flags on an output (7), which error flags are applied to a control unit (9). From these error flags the control unit (9) derives a control signal which is applied to a muting unit (6) for switching on the muting unit. A method is described by means of which the cont es the control signal from the error flags applied to its input (8). A first auxiliary signal (S1) is generated if (at least) n1 error flags are detected within a first time interval (T1) Subsequently, an i-th auxiliary signal (S i) is generated if (at least) n i error flags are detected within an i-th time interval (T i) which occurs after the instant at which the (i-1)-th auxiliary signal appears. The value of i ranges from 2 to N inclusive. Subsequently, a control-signal generator generates the control signal during a time interval T m which occurs after the instant at which the N-th auxiliary signal is received (Fig.2). A number of examples of the control unit are described.

Abstract: PROBLEM TO BE SOLVED: To attain acquisition of a natural synthetic picture by illuminating one of plural shape models with a light source model which has no directivity and illuminating shape models other than that with the light source model having the directivity. SOLUTION: A picture of a three-dimensional scene model generated by a object picture generation part 140 becomes a picture uniformly illuminated by a light source (an environmental light) with no directivity.

CONSTITUTION:The magneto-optical recording layer consists of the 4-layered constitution consisting of the 1st dielectric protective layer, the recording layer, the 2nd dielectric protective layer, and the metallic reflecting layer.

Abstract: PURPOSE:To simplify the structure and lower the cost by setting the shutter- release time of a mechanical shutter longer than a desired one, and releasing an electronic shutter for a desired time during that period of time. CONSTITUTION:The shutter-release time of a mechanical shutter is set longer than a desired one, and during that of time an electronic shutter is released for the desired time. By doing this way, the generation of smears can be reduced in spite of the high-speed shutter operation. Besides, high-resolution signals corresponding to frame pictures can be obtained, as the signal charges obtained by the light reception of all photoelectric receiving cells PD11-PD14, PD21-PD24 are read out by staggering the read-out times for odd fields and for even fields.
