Title: Semifixed variable resistor and manufacture thereof
Inventor: KOBORI HIROSHI
IPC: H01C10/34
Filed: 1990-04-19
Abstract: PURPOSE:To make it possible to chuck a semifixed variable resistor by air suction and carry it reliably, closing reliably the hole of an eyelet part, by forcing a plate-like cover in the cylindrical hollow portion of the eyelet part of a collector plate so as to close the hollow portion. CONSTITUTION:By performing the press working of a metallic plate 40, the external forms of an eyelet part 11, a central terminal 25 and a collector plate 7 are formed successively. Also, at this time, over the metallic plate 40, a band- like metallic plate 45 is provided, and further, a punch 50 is provided over the plate 45. When the eyelet part 11 of the collector plate 7 moves and reaches just below the metallic plate 45, the punch 50 punches the metallic plate 45 in the form of a disc, moving downward. The punched disc-like plate is used as a cover 9. The punch 50, holding the cover 9 at its end, further moves downward, and is inserted into the inside of a taper part (a) of the eyelet part 11 of the collector plate 7. Drawing back the punch 50 upward, the cover 9 is set in the eyelet part 11, in a state that the cover 9 is fastened firmly on the inner circumference of the eyelet part 11. Thereby, the cylindrical hollow hole of the eyelet part 11 is closed reliably by the cover 9. Therefore, a semifixed variable resistor 1 can be held reliably by the sucking part of a suction device.

Title: Drying of hollow lumber utilizing difference of air pressure
Inventor: MORI MITSUMASA
IPC: F26B21/10
Filed: 1990-04-20
Abstract: PURPOSE:To dry a hollow lumber without generating any crack by a method wherein the hollow part of the hollow lumber is evacuated and a pressure of air on the side surface of the outer periphery of the lumber is kept in a high pressure or a normal pressure while the drying of the lumber is effected from the hollow part at all times and, at the same time, heat energy is supplied from the side surface of the outer periphery of the lumber. CONSTITUTION:A hollow lumber 1, whose both ends are sealed, is placed in a pressurizing tank 10 and, thereafter, high-pressure water vapor is sent into the tank 10 to heat the lumber 1 without drying the same. When the temperature of a hollow part 3, which is detected by the temperature sensing unit 7a of a thermometer 7 placed in the hollow part 3 of the lumber 1, has arrived at a predetermined value, a vacuum pump 9 is operated to dry the hollow part 3 by evacuating and, at the same time, to reduce a humidity in the tank 10 and start the drying of the lumber 1 from the side surface 4 of the lumber 1. During drying, the reducing degree of the weight of the lumber 1 is measured by a weight meter 11 installed in the tank 10 to change properly the pressurizing degree, a temperature, a humidity and an air speed in the tank 10 and the evacuating degree of the hollow part 3 while monitoring the degree of drying whereby the drying speed of the lumber 1 is regulated so as not to generate cracks in the hollow lumber 1.

Title: Metering pulse detector
Inventor: SUZUKI AKIRA
IPC: H04M15/28
Filed: 1984-05-23
Abstract: PURPOSE:To use a capacity with small capacity by multiplying a frequency of a metering pulse and using a band pass filter to detect it. CONSTITUTION:When the metering pulse is transmitted through telephone lines L1, L2, it is inputted to an input terminal of a phase comparator circuit 3 constituting a PLL circuit. Since a voltage controlled oscillator 5 is oscillated in a frequency where a frequency frequency-dividing the oscillated frequency at a 1/N frequency divider 6 and a frequency of the metering pulse are coincident, the frequency of the metering pulse is multiplied by N times. The signal multiplied by N times is fed to a band pass filter comprising resistors R4-R6 and capacitors C3, C4, detected and waveform-shaped. Thus, the value of the capacitors C3, C4 being components of the band pass filter is decreased to 1/N.
