Title: Recording and reproducing device and record medium capable of reading with computer
Inventor: HONDA KIMIFUMI
IPC: G11B15/467
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To easily ascertain the difference in track levels between the original recording area (ITI area) and the insert recording area (area other than ITI) as to the AV insert recorded track in the tracking system of a VTR. SOLUTION: When an adjustment mode is selected by a selection SW 19 at the time of reproducing the AV insert recording part of a tape 1, the tracking operation is executed for the original recording area (ITI area) of the tape 1 by a tracking control part 7. By an error correction part 17 of reproduced information data, error data are detected from the data reproduced by heads (a), (b), and a rate of the error data amount to the correction and all information data amount is calculated and displayed on an error rate display part 18. The error rate of the insert recording area is monitored thereby, and the signal deterioration of the reproduction error rate caused by the difference in track levels is ascertained.

Title: Temperature measuring circuit in thermal cooking apparatus
Inventor: HIDA KIYOTOSHI
IPC: A47J37/00
Filed: 1991-03-15
Abstract: PURPOSE:To detect a fault such as a disconnection of a temperature sensor or the like (opening of a circuit) by making a resistance value of an impedance circuit able to be changed to a resistance value corresponding to one or a plurality of detecting temperatures and to a high resistance value. CONSTITUTION:This temperature measuring circuit is constituted of a CPU 10, a transistor 11 actuated by a signal from an A terminal of the CPU 10, a reference voltage source S connected to one end of a thermistor via the transistor 11, and a resistance R (R1, R2...R5) interposed between the transistor 11 and the thermistor 7. Four of the five resistances (R1, R2...R5) are set at the same resistance value as that shown when a specific temperature is detected by the thermistor 7. Only one of the resistances is set at a greatly higher resistance value than the resistance value of the thermistor at the ordinary temperatures. In other words, if such a fault as a disconnection or the like is not brought about, a considerably low voltage appears at both ends of the thermistor 7 when the thermistor 7 is switched to the one resistance.

IPC: C04B37/02
Filed: 1995-03-10
Abstract: PURPOSE: To provide a method for joining a ceramic to a metal by which the strength and air tightness of a joined part can be strictly maintained over a long period of time. CONSTITUTION: Active metallic foil having 1-50μm thickness made of an active metal selected from among Ti, Zr, Cr and Hf is put on a practically flat table and a metallic sheet for laminating having 10-300μm thickness is pressed against the foil under >=1t/cm<2> pressure to press-bond the foil to the sheet. The ratio of the thickness of the sheet to the surface roughness is 5-100. The resultant laminated body is interposed between a metal and ceramic to be joined to each other so that the active metal of the laminated body is brought into contact with the ceramic and the laminated body is heated to join the metal to the ceramic by fusion through the laminated body. Strength is improved and airtightness required by a vacuum bulb is ensured.

Title: Headed rod member feeder
Inventor: MAE TAKAHARU
IPC: B65G47/14
Filed: 1984-03-17
Abstract: PURPOSE:To prevent biting and flawing of headed rod members which would be caused by protrusion of a push rod by protruding the push rod into a hopper by the force of a resilient member only when a blade is lowered to the vicinity of the lowermost portion of the hopper. CONSTITUTION:As a rotor 9 is turned around, a segment blade 3 is downwardly swung along a groove 21 of a semicircular plate 5 until it is swung to the vicinity of the lowermost portion of a hopper 1. This swinging movement causes a roller 18 of a switch 17 to be pushed by the end surface 3b of the segment blade 3 and thereby air flow into an air cylinder 13 to be stopped. Such a stop causes a rod 13a to be put in the retracted state by a spring 13b, and a push rod 15 starts to be protruded into the hopper 1. Such a protrusion releases the headed rod members from firm engagement and stacking of the stems thereof at both sides of the segment blade 13, and as the result, the stems of the rod members fall down to a groove 3a of the segment blade 3 and are caught there.
