Patent JP-H01200158-A (JP)
Title: Stirling engine
Inventor: IWATA YUJI
IPC: F25B9/00
Filed: 1988-02-04
Abstract: PURPOSE:To prevent sound and vibration from being generated by providing a crank mechanism having a crankshaft forming a first crank part, a second crank part having the same phase with that of the first crank part and a third crank part having a predetermined phase difference from the phase of both crank parts, and driving respective pistons. CONSTITUTION:The bifurcate part at one end of a second cone rod 7b is split clamped to a second crank part 21b of a crankshaft 21 and a third crank part 21c thereof. The other end of the second cone rod 7b is connected to a second piston 5b at a second pin 6b. For this reason, a force from a second piston 1b acts uniformly 1/2 of the force each on the crankshaft 21 through the second crank part 21b and the third crank part 21c. But a substantial operating point is in the same position with the first crank part 21a. Accordingly, no couple moment is generated in the crankshaft 21 and it is possible to prevent sound and vibration from occurring.

Filed: 1988-02-04
Abstract: PURPOSE:To reduce the manufacturing cost, by forming a fine wiring region and an external terminal region by the use of a common mask and plating the outer terminal region while covering the fine wiring region with a mask material easy to be separated. CONSTITUTION:The present integrated circuit device ot be manufactured includes a fine wiring region which requires a higher accurate patterning and an external terminal region which is patterned relatively gradually with good quality.

Title: Crosstalk measuring instrument
Inventor: YAMAKAWA AKIO
IPC: G11B7/26
Filed: 1990-02-06
Abstract: PURPOSE:To easily measure a crosstalk level by extracting frequency corresponding to a horizontal synchronizing signal in an FM video signal obtained by FM converting a reproduced video signal through a filter and displaying the extracted output on a time axis. CONSTITUTION:The reproduced video signal reproduced from an optical disk CLV having a fixed linear speed is converted into an FM signal by an FM modulator 22 and modulation frequency corresponding to the horizontal synchronizing signal level of the FM video signal is extracted through a band pass filter(BPF) 23. When the output of the BPF 23 is displayed on the horizontal period time axis of a display part 26, a crosstalk level from adjacent tracks appears on the intermediate of spans on a display screen. The crosstalk level can be known by measuring a waveform level indicating the crosstalk level. Thereby, the crosstalk level can easily be measured even in the case of using a CLV type optical disk.

Title: Initial power source input detecting circuit
Inventor: SAKATA MINORU
IPC: G06F1/24
Filed: 1988-02-08
Abstract: PURPOSE:To enhance reliability by detecting the rise of an output level by a power source level rise detecting means and outputting an initial power source input detection signal. CONSTITUTION:The initial power source input detecting circuit is equipped with DFF circuits 10 and 20 and a microcomputer 30 and has a switch 11 to operate a system. When the switch 11 is closed, a power source VSW becomes on. A power source VB is impressed on a data input terminal D of the FF circuit 10 and a signal CLR1 to become effective when it lowers is impressed on a clear input terminal. Consequently, the FF circuit 10 is not cleared immedi ately even when the power source VB is cut off for an instant but outputs until the supply of power is cut off. The FF circuit 20 impresses the VB on the data input terminal and impresses the Q output of the FF circuit 10 on an edge trigger input terminal. Consequently, the <->Q output of the FF circuit 20 falls at the rise of the Q output of the FF circuit 10 and rises to a reset signal. The initial power source input detection signal is outputted to the micro computer 30.

Other terminals requesting the transmission right detect this flag, first three flags are passed through and transmission right is obtained by inhibiting the final flag. The terminal transmitting the flag detects the flags returned by only three via the loop and confirms that the shift of the transmission right to other terminals.

Title: Peak holding circuit
Inventor: FUKUOKA TAKASHI
IPC: H04B10/07
Filed: 1988-02-08
Abstract: PURPOSE:To reduce ripple noise by providing the title circuit with an impedance circuit connected to a switching means and determined so that its impedance is high at the initial stage of a response and then the impedance is gradually reduced to control current flowing into the switching means. CONSTITUTION:An impedance circuit Z is constituted of a secondary delay response circuit based upon a parallel circuit consisting of a resistor R and a series circuit constituted of an inductance L and a capacitor C. When the amplitude of an input signal Vin is sharply changed, the circuit rapidly responses and holds its peak value, and when the amplitude of the input signal Vin is not sharply changed, slowly responses. Since the speed at the initial stage of the response is set up to a slow speed and the speed is gradually increased, noise can be reduced when a variation of the peak value Vin is small, and a response speed can be increased when the variation is large.

Title: Magnetic flux quantum logic element and asynchronous counter
Inventor: AIHARA KIMIHISA
IPC: H01L39/22
Filed: 1988-02-08
Abstract: PURPOSE:To prevent a decrease in margin due to a multiple-stage connection by making it possible to form an inductance loop in a branch part of a resistor link branch of a Josephson line. CONSTITUTION:An auxiliary bias current i is supplied only to the input terminals of a Josephson line 2, so the magnetic flux quantum propagated through a Josephson line 1 is set so as not to propagate to a line 3. When the magnetic flux quantum is propagated from the line, it invades the line 2. And one of the ends of the magnetic flux quantum is propagated to an output terminal T2 and the other end thereof is held in the superconducting loop arranged between the lines 2 and 3. At this time, a loop current accompanying the magnetic flux is caused to flow in the direction from the lower electrode to the upper electrode in the input terminal of the line 2, and from the upper electrode to the lower electrode in the line 3 through the superconducting loop. So this has the same effect as when an auxiliary bias current i is supplied in the input terminal of the line 3. When the next magnetic flux quantum is propagated under this condition, it propagates to the output terminal of the line 3, and it undergoes pair annihilation with the magnetic flux quantum held in the superconducting loop as well. This makes it possible to arrange a flip-flop with a simple circuit arrangement.

Filed: 1985-02-13
Abstract: PURPOSE:To reduce friction on the surface at the joint of an endless belt and to enhance durability by forming a protective film including a specified solid lubricant on the surface of the joint for joining both ends of a photosensitive belt.

Such a protective film 4 is pre pared by dispersing said solid lubricant particles into a solvent soln. of resin or rubber, and coating the surface of the joint 3 with the obtained coating fluid, and drying it. Since the protective film 4 contg. such a solid lubricant is formed on the surface of the joint 3 of the electrophotographic endless belt to reduce friction, friction between the belt and each kind of members arranged around the photosensitive belt at the time of sliding contact with each other is weakened, and its durability can be enhanced.
