Patent JP-S59186408-A (JP)
Title: Current supply circuit
Inventor: HOUYA KAZUO
IPC: H03F3/45
Filed: 1983-04-08
Abstract: PURPOSE:To prevent the generation of an offset voltage by an input resistance by varying the output circuit of a compensating circuit which compensates a base current according to the hFE of a transistor (TR) supplied with the output current as its base current. CONSTITUTION:Transistors (TR) Q1, Q2, Q3, etc., constitute the base current compensating circuit. Then TRs Q1, Q5, and Q6 are NPN types, and the Q2 and Q3 are PNP types having equivalent hFE. Therefore, the emitter-base current IBE3 of the TRQ3 is nearly equal to the base current IBE5 of the TRQ5. Therefore, when a source voltage +VCC is supplied, the current IBE3 is supplied to the base of the TRQ5 and an input current is ceased. Consequently, no current flows through a resistance R2 and the base of the TRQ5 is held almost at a potential VREF. Further, when R2>R1, the TRs Q5 and Q6 are almost balanced and no offset voltage is developed between the two.

Title: System for decreasing output terminal
Inventor: AKIBA HIROSHI
IPC: G06F3/00
Filed: 1984-03-30
Abstract: PURPOSE:To decrease the number of output terminals by grouping signals which are outputted simultaneously and signals which are not outputted simultaneously and providing a selector for switching those signals, and thus sharing output terminals. CONSTITUTION:Output signals CA**1 and CB**1 of a control system are selected by the selector 3 and a signal CC**1 is outputted as an output signal. Further, a signal CID1 which determines the selector output is supplied to a high-priority board 1 as it is and to a low-priority board 2 while inverted through an inverter 4. In this case, a signal generated only by the board 1 is specified as the signal CA**1 and a signal generated only by the board 2 is specified as the signal CB**1. Then, logic 0 is determined for the board 1 and logic 1 is for the board 2; and the signal CID1 is fixed at 0, thereby eliminating output terminals which becomes unnecessary as a result of bit slicing. Namely, the CB**1 of the board 1 and the CA**1 of the board 2 are fruitless signals and they are not sent to output terminals and selected by the selector to decrease the number of output terminals.

Title: Heat exchanger
Inventor: TANITOU YOSHIO
IPC: F28D11/04
Filed: 1982-04-14
Abstract: PURPOSE:To increase an area of a flow path for a fluid to be cooled of a heat- exchange body, to reduce the resistance of ventilation and to prevent the generation of clogging by making a shortest pitch of a tube on a circumferential pitch circle of the tube approximately constant. CONSTITUTION:When a centrifugal fan 15 is turned while tanks 3a, 3b are supplied with the fluid to be cooled by pipes 6a, 6b, the fluid to be cooled is cooled by cooling air through fins 22a, 22b. Direct transmission over the heat- exchange bodies 23a, 23b of external vibration and shocks can be prevented because packings 24, 25 are set up among both tanks 3b, 4b, 5a and tanks 3a, 4a, 5b and plates 1, 2. The tanks 3a, 3b, 4a, 4b, 5a, 5b are positioned easily because knocks 20 are formed to the tanks 3a, 3b, 4a, 4b, 5a, 5b. The actual spaces of the tubes 21a, 21b are approximately equal at any position of the heat-exchange bodies 23a, 23b because the shortest pitches of the tubes 21a, 21b are made approximately equal.

Title: Detecting apparatus for surface defect of body
Inventor: TAKAOKA SHIYUUJI
IPC: G01N21/952
Filed: 1980-05-07
Abstract: PURPOSE:To irradiate the surface to be inspected from the normal direction thereof and make it possible to detect the surface defect of an object to be inspected which has a spherical surface or the like by providing a lens on the optical path between a light source and an object to be inspected so that the light-source image is focused on the center of curvature of the surface of said object. CONSTITUTION:The light from a light source 1 is passed through a circular slit 3, a half mirror 6 and a first lens 7 and applied to the surface 9 to be inspected to an object 8 to be inspected which has a spherical surface or surface of revolution of circular arc. Because the lens 7 is arranged so that the image of the light source is focused on the curvature center O of the surface 9 to be inspected, the illuminating light is applied from the normal direction of the surface 9 to be inspected. Consequently, the light reflected from the whole surface 9 to be inspected is focused on the front surface of an image scanning apparatus 11 through the lens 7, the half mirror 6 and a second lens 10. When a surface to be inspected which has a spherical surface or the like is irradiated with parallel rays, a real image of only a part can be obtained because the rays reflected from the surface to be inspected are diffused. However, irradiation from the normal direction permits a real image of the whole to be obtained.

IPC: F04D27/02
Filed: 1989-03-15
Abstract: PURPOSE: To avoid unnecessary loss of pressure or energy by continuously measuring flow rates and discharge pressures to obtain a moving speed of an operating point against a blow-off line or a surge limit, and controlling a blow-off valve corresponding to this speed. CONSTITUTION: A flowmeter 4 is disposed in an intake line 10 of a turbocompressor 1, and a pressure gauge 5 is disposed in a discharge line 11. A blow-off line 21 with a blow-off valve 2 branches from the outlet line 11. The position of the blow-off valve 2 can be adjusted by means of an activator 20. The results of the measurements of flow rate and pressure are employed to calculate a regulation difference, and further calculate an manipulated variable of the blow-off valve 2. A moving speed of an operation point of the compressor 1 is calculated from the regulation difference so as to find out whether the operation point approaches a blow-off line or a surge limit, and to obtain the speed of the approach. A rapid opening controlling device forms a control command for the blow-off valve 2 on the basis the regulation value and the operation point moving speed.

Abstract: PURPOSE:To secure a stabilized phase for the waveform of a driving signal to ensure a steady tracking action of a rotary head and at the same time realize a high- quality slow motion reproduction, by using a signal of a prescribed period for the driving signal of the rotary head. CONSTITUTION:A consecutive scan is given to a tape 2 having a recorded track at a speed of 1/N times as high as that of a recording mode by means of the rotary heads A and B provided to a rotor opposedly to each other. In this case a pulse (i) obtained by detecting the rotation of the rotor and a control pulse (j) recorded previously on the tape 2 and having the traveling phase information are applied to an FF37. Then a signal having a period equal to the 2N track scan period synchronous with the output of the FF37 is applied to a head moving mechanism 4. Thus a driving signal is obtained to give a substantial displacement to the heads A and B in the opposite direction to each other and by an equal degree. Then a signal (j) is supplied to the timers 41 and 42 in the form of a trigger pulse to secure a synchronism between the changing point of a driving signal waveform and the scan position of the tape 2.

Title: Signal transmitting system for facsimile
Inventor: TAKEKAWA TAKASHI
IPC: H04N1/00
Filed: 1981-04-23
Abstract: PURPOSE:To obtain high-speed performance through a simple analog modulating/ demodulating circuit, by setting the carrier frequency of a picture signal on an area in which large distortion generates in a transmission line of the transmitting side and providing the receiving side with an automatic equalizing circuit. CONSTITUTION:A picture signal photoelectrically converted from the black- and-white information of a transmitted original is ternary-converted by a ternary-converting circuit 11 and the carrier frequency is amplituded and pulse- modulated in a modulating part 12. In this case, the carrier frequency is set to about 3,000Hz in which large distortion generates in the transmission line. The modulated signal is vestigial side band (VSB)-shaped by a VSB filber 14 and sent to the transmission line. In the receiving side, a clear demodulated signal is obtained through a filter 21, an automatic gain controlling (AGC) circuit 22, an automatic equalizing circuit 23, and a demodulating part 24. Consequently, signals can be transmitted quickly by increasing the carrier frequency until the influence of line distortion is largely exerted.
