Title: Material body detector
Inventor: MAKINO MASAMI
IPC: G01S17/04
Filed: 1985-04-08
Abstract: PURPOSE:To provide the titled detector which is optical and easily set up by providing a photodetecting means making almost the Whole area a detecting area with reference to plural detection beams. CONSTITUTION:The rays of light from light emitting diodes 21-23 are emitted in each detecting direction as the detection beams 24-26 via a lens 27. A photodetection part 3 converges the reflected rays of light 31-33 from the detecting area by the beams 24-26 in a prescribed area by a lens 34. Then, an output signal of a semiconductor position detector 35 having the detection face covering the whole converging area is converted into an analog signal corresponding to the position on the detection face with a converting circuit 43 and inputted to a microcomputer 41 via an A/D converter 44. An output signal of the converter 44 at the time when one of the diodes 21-23 is selected in an alternative way and emitter by the computer 41 is read and the existence and position of a material body at the detecting direction are decided and the decided result of the detection of the material body is informed 45. Accordingly, since it is not necessary to set the photodetecting means individually for the plural detection beams and it is only necessary to set the photodetecting means having the comprehensive detecting area, the detector is easily set up although it is optical.

Title: Up-and-down device of wick of liquid fuel burner
Inventor: SHIROUCHI TOYOKAZU
IPC: F23D3/32
Filed: 1984-04-13
Abstract: PURPOSE:To contrive facilitation in incorporation work and reduction of cost by performing monolithic molding of a connecting component, by a method wherein the center line of a rotation of a wick adjusting shaft and the center line of the rotation of a fine adjustment component are provided about in parallel with each other, and an end part of a cone of the wick adjusting shaft is welded with pressure to a circumferential wall of a conical cylinder of an end part of the connecting component the other end of which is connected with a part of the fine adjustment component. CONSTITUTION:A wick adjusting shaft 7 and a stepped pin 40 forming the center line of a rotation of a fine adjustment component 39 rotating by an operation lever 47 are provided about in parallel with each other. An end part of a connecting component 52 is connected rotatably by a male screw 39b and a female screw 52d with a part of the fine adjustment component 39. An end part 7a of cone of the wick adjusting shaft 7 is welded to a circumferential wall 52b of a conical cylinder of the other end part of the connecting component 52 with pressure. Although ascending force of the wick transmitted through the fine adjustment component 39 and descending force of the wick transmitted through the up-and-down device 32 of the wick and the fine adjustment component 39 from the operation lever 47 are transmitted to the wick adjusting shaft 7, if the wick adjusting shaft 7 is rotated a little stronger, a slide is generated on the pressure-welded part between both. Then the wick adjusting shaft 7 can be rotated independently and an exposed length of the wick can be adjusted. As the centers of them coincide with each other, even if the slide is generated the connecting component 52 can be made into a monolithic-molded article. Incorporation can be performed easily and rapidly.

At this time, another operator is informed by voice that the copying operation is not finished or that the copying machine is not set in the standard mode with a signal for detecting the arrival of the operator and the end signal of the copying operation.

Title: Optical recording medium and recording regeneration method
Inventor: UEJIMA ATSUSHI
IPC: G11B7/004
Filed: 1990-03-27
Abstract: PURPOSE:To correctly write signals and read the recording signals by a method wherein an optical recording medium is produced by providing a recording layer group and a light absorbing, heat-generating layer absorbing a light emitted on a position abutting on the recording layer group and converting the light to heat on a substrate. CONSTITUTION:A laser beam is emitted while taking aim at a light-absorbing, heat-generating layer 5 absorbing a laser beam LB and converting it to heat. A plurality of thermal recording layers 3n disposed adjacent to the light- absorbing, heat generating layer 5 and a plurality of heat insulating layers 4n are alternately laminated. As a result, when the heat generated in the light- absorbing, heat generating layer 5 is transmitted in the thick direction of the recording group 6, a thermal change per recording layer can be clearly discriminated by the heat insulating action of the heat insulating layers 4n. The action of the heat insulating layers 4n can be used as a value for restricting an error signal recognition. A signal pattern multivalued by a discrete density change by the recording layer group 6 enables recording and regeneration to be conducted on accurate signals.

Abstract: PROBLEM TO BE SOLVED: To maintain a high-speed writing system, and at the same time to reduce fluctuation of a threshold after writing in a non-volatile semiconductor memory such as a flash memory in a channel hot electron writing system. SOLUTION: In a device, a current detecting writing circuit 2 and a sensing amplifier 1 for reading are provided.
