Inventor: ICHINOSE AKIRA
IPC: G11B20/18
Filed: 1983-09-30
Abstract: PURPOSE:To improve the sector using efficiency with no increment of demodulation errors by checking a data mark part showing the initiation of data with higher strictness than other parts and therefore making use of the capacity of an error correction code to correct a demodulation error owing to the dropout of a coding data part. CONSTITUTION:Switches 10 and 12 are turned on in a period equivalent to a data mark part and in a record mode together with switches 9 and 11 turned off respectively. While switches 9 and 11 are turned on with switches 10 and 12 turned off respectively out of the period equivalent to the data mark part. Therefore the comperison rate level voltages G and H are set at V3 and V4 respectively in a data mark period. While the G and H are set at V1 and V2 respectively in other periods. Then it is possible to detect even a pulse smaller than those of other periods among pulse signals contained in a signal S in a data mark period by setting V3 smaller than V1 and setting V4 larger than V2 respectively.

Title: Cryogenic refrigerating machine
Inventor: FUJIMOTO SHUJI
IPC: F25B9/14
Filed: 1990-07-09
Abstract: PURPOSE:To shorten the cooling down time period and maintain the refrigerating capacity by a method wherein the surge volume on the cylinder side of an expansion device is made smaller than that on the valve motor side, and those surge volumes are connected to each other by a pipe. CONSTITUTION:In an expansion device 2, the high pressure gas supplied from a compressor 1 is adiabatically expanded to generate cold of a cryogeic level, and the expansion device 2 is separated into two assemblies, a cylinder assembly 3 and a valve motor assembly 40. The cylinder assembly 3 is provided with a surge volume 7 which communicates with an intermediate pressure chamber 13, and the valve motor assembly 40 is furnished with a surge volume 47 having a larger volume than the surge volume 7. As the surge volume 7 is smaller in volume than the surge volume 47, the surge volume 47, having a larger volume is prevented from being heated up even when the compression heat taken away by the gas at the low temperature end of a cylinder 10 retains in the normal temperature part, so that the intermediate pressure is prevented from rising excessively. Consequently, the differences between the intermediate pressure and the high and low pressures are properly kept and the reciprocating motion of a displacer 16 is stabilized, so that the cool-down operation time period can be shortened and the refrigerating capacity during normal operation can be enhanced.

IPC: F24F1/00
Filed: 1983-09-30
Abstract: PURPOSE:To permit an air purifying device in a vehicle or the like to be operated with average fouling by rotating normally a blower motor with low speed, rotating it with high speed upon detecting a certain concentration or more of smoke and thereafter changing over the rotation to the medium and low speed every a certain time. CONSTITUTION:A blower motor is normally rotated with low speed to flow gently indoor air, mix, average and introduce it into a smoke sensor 5 to monitor air fouling. When the smoke sensor 5 detects a certain concentration or more of smoke, a fan is changed over to the high speed rotation while a timer is driven. Thus, indoor air is forcibly sucked to purify air. After a timer set time elapses, the fan is changed over to the medium speed running and when the smoke detecting output becomes zero, the fan is changed over to the low speed rotation after a certain time. By this constitution, this device is not run controllably with a local condition judgement, but with average air fouling to average the purifying function.

Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor circuit which is capable of limiting a leakage current to an irreducible minimum bringing out most a speed improving effect caused by a low threshold voltage. SOLUTION: A delay path region where a gate element lowered in threshold voltage is applied is limited to a range from the maximum delay value 23 (faster than this) before a gate element lowered in threshold voltage is applied to the new maximum delay value 24 (slower than this) when a gate element lowered in threshold voltage is applied.

Title: Control device for pneumatic type automatic clutch
Inventor: HISAMURA HARUYOSHI
IPC: B60W10/10
Filed: 1982-10-22
Abstract: PURPOSE:To make clutch termination full at low speed rotation and improve air to fuel ratio by providing a clutch full termination control valve that sets a starting valve to the start or full termination oil pressure status depending upon the case where the car speed is below or exceeds the full termination car speed. CONSTITUTION:A clutch full termination control valve 108 has a rod 182 at the left side below the full termination car speed and at the right side beyond the same car speed. Thus, a starting valve 116 controls the start pressure of a port 204a at the start oil pressure adjustment status so as to correspond to the engine rotating speed signal oil pressure that is actuated on a port 204d. Since this start pressure is supplied to a clutch 36 for advance through a manual valve 104, the clutch actuation pressure is raised depending upon the engine rotating speed. When a car reaches the car speed exceeding the preset one, the control valve 108 is switched and supplies the drive pulley rotating speed signal oil pressure to a port 204e through an oil path 190. As a result, the start pressure of the port 204a is raised to the full termination oil pressure adjustment status and a clutch 4 can fully be terminated and run even at low speed rotation.
