Title: Control circuit for dc motor
Inventor: GOMITA HISAMITSU
IPC: H02P7/288
Filed: 1982-12-20
Abstract: PURPOSE:To enable to control the speed of a DC motor by following up the variation in an external analog or digital signal by providing an analog-to- digital converter in a control circuit for the motor. CONSTITUTION:A motor control circuit 13 controls a DC motor 1 for driving a pulley 22 which winds a wire 16 in response to the deviation between a speed command and a speed signal from an encoder pulse converter 6.

Title: Plasma x-ray generator
Inventor: KATO YASUO
IPC: G03F7/20
Filed: 1986-09-22
Abstract: PURPOSE:To reduce the time required for exchange, shorten the discharge interval, and increase the number of wafers processed in a unit time by providing a means performing the exchange of the gas in a discharge tube intermittently with respect to the discharge interval. CONSTITUTION:An operation discharging the gas in a discharge tube and filling the new gas is not performed for every discharge but is performed intermittently at a fixed interval. If the occluded gas is sufficiently discharged to a high degree of vacuum for usage, the discharge of the impure gas in the discharge tube is relatively small even after several tens or discharges, and the decrease in strength of X-rays generated is small without the gas exchange. The reduction of the processing speed of a wafer can be prevented by exchanging the gas synchronously with the movement of the exposure region of the wafer or the exchange of the wafer intermittently without performing an operation discharging and filling the gas for every discharge.

IPC: E04C2/04
Filed: 1997-08-19
Abstract: PROBLEM TO BE SOLVED: To simplify site work by including a plate-shaped fire resistant layer with fire resistant performance, and a plaster layer formed on the fire resistant layer, and integrally-forming the fire resistant layer and the plaster layer previously. SOLUTION: A fire resistant building material 10 is formed by overlapping a plaster layer 14 on a plate-shaped fire resistant layer 12 to integrate both of them, and in the fire resistant layer 12, the cement mixed with inorganic fiber material consisting of ceramic fiber, glass fiber, or the like is formed into a plate shape. The plaster layer 14 is formed by applying plaster with the thickness of approx. 0.1 mm uniformly on the fire resistant layer 12, and the plaster layer 14 and the fire resistant layer 12 are integrated easily without adhesive because the plaster itself has an adhesive strength. The plaster layer 14 serves as surface facing, therefore, the plaster layer 14 is fitted to face interior side, so that a finishing process, such as wall paper affixed to a construction site is eliminated.  It is thus possible to simplify construction site work, and obtain the fire resistant building material which is tender against the environment or a human body.

Title: Dot line printer
Inventor: NAKAI TOSHIHIKO
IPC: G06K15/10
Filed: 1982-12-20
Abstract: PURPOSE:To prevent interruption of printing operation regardless of printing pattern by shifting the printing with the reciprocation of a printing head from the bidirectional to unidirectional when the detected value of an output current of a power source unit exceeds a specified value. CONSTITUTION:Normally, printing is operated to feed a paper by one pitch each time the reciprocation of a printing head 10 is done. As a current detection value Vc from a power source unit 1 with a detection circuit 2 exceeds a set voltage, an H signal is outputted from a printing operation control circuit 3 and a control section 5 reads out a dot line data only for the outgoing action to perform a unidirectional printing while the paper is fed by one pitch each time reciprocation is done. A signal ST is fed to the control circuit 3 at a specified time interval with a timer 4 to return the printing to the bidirectional mode when the signal Vc is below a specified value or otherwise, the printing is maintained in the unidirectional mode. This can reduce the average load current without causing poor printing or interruption of printing operation regardless of printing pattern thereby enabling continuation of printing.

Title: Delay detection and demodulation circuit
Inventor: ADACHI FUMIYUKI
IPC: H04L27/22
Filed: 1989-08-28
Abstract: PURPOSE:To attain high speed compensation for a frequency drift by correcting the phase of a complex number delay detection output so as to minimize the displacement of two outputs on a complex number plane. CONSTITUTION:A received phase modulation wave from an input terminal 1 is inputted to a delay detection circuit 2, in which the received phase modulation wave is detected by using a phase of one preceding time slot as a reference. Two received waves are multiplied as they are to obtain a sinusoidal delay detection output. A delay circuit 5, a complex number conjugation circuit 6, a complex number multiplication circuit 7 and a moving mean circuit 8 obtain a compensation coefficient to apply sign decision with the calculation of a complex number multiplier circuit 9. Thus, the phase rotation of the delay detection output due to the frequency drift is corrected to compensate a carrier frequency drift at a high speed.
