Patent JP-S5857805-A (JP)
Title: Stereo equipment
Inventor: ENOKI TAKASHI
IPC: H03F3/181
Filed: 1981-10-01
Abstract: PURPOSE:To simplify the operation, by performing the switching of a designated music source at a designated time, through the use of a signal from a timer circuit. CONSTITUTION:When a signal from a record disc is selected at a stereo device, a Q-output of an FF41 goes to ''H'' level and a Q-output of an FF51 goes to ''L'' level. In this state, a function set switch 62 is operated to supply an output signal of a timer circuit 61 to the FF. The output signal of the timer circuit 61 goes to ''L'' level after a prescribed time. Thus, the input S' of the FF51 goes to ''L'' level and the input S' of the FF41 goes to ''H'' level. Thus, the music source is changed over from the record disc into a tuner.

Filed: 1984-07-25
Abstract: PURPOSE:To improve the accuracy of reading by incorporating a CCD in a coordinate reader, detecting the coordinates of a current position by two or more detecting means or the like and operating and numerizing the parallel movement and turning angle of a cursor part. CONSTITUTION:The coordinate reader is provided with a reading part 3 on a linear graphic 2a drawn on a drawing 2 laid on a plane base plate 1.

Title: Die for rotation forming
Inventor: FUJITA MASAJI
IPC: B21B27/00
Filed: 1982-09-06
Abstract: PURPOSE:To prevent surely deformation of a die due to temperature rise and to obtain a titled die high in working accuracy, by forming a part or the whole of a die by using ceramics low in coefficient of thermal expansion and high in abrasion resistance. CONSTITUTION:As an example of a die for rotation forming used for manufacture of counter gears for automobile, a following material is used for die pieces consisting of a die 1. Ceramics low in coefficient of thermal expansion and high in abrasion resistance is used for messers 1b, 1b on both ends of left and right rolling supports and a messer 1c at the center instead of using a steel material such as alloy tool steel. For instance, ceramics of alumina group, silicon nitride group, silicon carbide group, etc. are used as the ceramics. This die for rotation forming exerts very little thermal influences on the die at the time of rotation forging. Especially, the die made by combining materials of different kinds reduces the thermal stress generated in the alloy tool steel, and can absorb local warping and swelling of the die by the ceramics part. Similar effects can be obtained when the whole of the die 1' is formed of ceramics.

Abstract: PURPOSE:To enable storage of combustion data, by processing signals from a switch, a sensor and a setter on the basis of a combustion processing program stored in a program memory, and using an electrically erasable programmable read-only memory (EEPROM) as the program memory. CONSTITUTION:Combustion control data, such as maximum and minimum rotational frequencies of a burner fan 12 and a hot-air fan 13, maximum and minimum frequencies of a fuel pump 14, and a heater ON/OFF set temperature to be compared with a temperature detected by a burner temperature sensor 9, is sent to a microcomputer 11 capable of communication through a data- setting board 28 by operating switches 20A on a memory input/output device 21, and is stored into a memory part 25A of an EEPROM 25. The microcomputer 11 counts the time for which an operating switch 2 is closed and the duration of combustion, integrates the times thus counted, and stores the integrated times in memory part 25A of the EEPROM 25. Since the data in the memory part 25A is not lost even upon service interruption, the data of the integrated use time and the integrated combustion time can be displayed on a display device 16 by operating a switch 20B, for example.

Title: Optical recording method
Inventor: UENO ICHIROU
IPC: G11B11/05
Filed: 1980-11-05
Abstract: PURPOSE:To prevent a bad influence exerted on a tracking control signal due to a variation of a recording laser beam, by recording the tracking control signal on both sides of an information signal, at the same time. CONSTITUTION:As for a laser light beam emitted from a laser light source 40, its intensity is modulated by an information signal in an optical modulator 10, and an image is formed as shown by 21 on an optical disk D. Also, as for the laser beam reflected by a half-mirror 9, its intensity is modulated by a tracking control signal in optical modulators 22, 28, and images 34, 35 are formed on the optical disk D. According to such constitution, even if a short-time output drop or output stop occurs in the laser light source, the tracking control signal is a nonrecording state at the same time on both sides of an information signal, therefore, when reproducing, the tracking control operation does not go out of order.
