Title: Magnetic tape buffer mechanism
Inventor: YANO MINORU
IPC: G11B15/58
Filed: 1979-01-23
Abstract: PURPOSE: To cause a magnetic tape to run stably for high-speed running, start and stop of the magnetic tape by providing a sub-tank connected inside left and right sub-columns of the magnetic tape device and by connecting the sub-tank to a negative pressure source.  
     CONSTITUTION: Insides of left and right sub-columns 5 and 6 are connected to each other in part S 1 , and further, they are connected to sub-tank 7 in part S 2 . A negative pressure is given through air hole 8. At an advance start time, the tape in sub- column 5 goes deeper, that is, the curvature becomes small, and the tape in sub- column 6 is tried to be led out to the external direction. Since air flowing entrance S 2  is sufficiently smaller than S 1 , the negative pressure in sub-column 5 is lowered at the first instant, and the negative pressure in sub-column 6 tries to increase, however, the negative pressure is not changed bacause they are made into one body, and a habit to keep the normal position is given. Consequently, the magnetic tape can be run stably.

Title: Tubular body coupling structure
Inventor: IGUCHI HIROYUKI
IPC: F16L19/04
Filed: 1998-01-19
Abstract: PROBLEM TO BE SOLVED: To improve the fatigue resistance by tilting a back side part of a flared part to the direction opposite to the pressing direction of a tightening member when the flare part in which an end part of a tubular body is expanded, is butted to a body to be coupled, and the tubular body is coupled with the body to be coupled by pressing the flare part against the body to be coupled by the tightening member. SOLUTION: In coupling a tubular body 1 to an ABS actuator 2 as a body to be coupled, a flare part 11 at a tip of the tubular body 1 is inserted in a hole 22 in the actuator 2, and a outermost end part 11a of the flare part 11 is abutted on a distal wall of the hole 22. Then, a flare nut 4 is advanced to the hole 22 in the actuator 2, a thread 41a is screwed to a screw groove 22a of the hole 22, and the tightening torque is given thereto using a wrench, etc. Because the angle of inclination of a flange back part 11d is set to be smaller than the angle of inclination of a tip surface 41b of the flare nut 4, an edge part of the tip surface 41b of the flare nut 4 presses the flare back part 11d to deform the flare part 11, its fatigue resistance is increased.

Filed: 1987-01-16
Abstract: PURPOSE:To attain the highly accurate measurement while using a very inexpensive system by providing a digital pattern generator, a DC level reader and a digital signal processing unit. CONSTITUTION:At first a digital pattern 000-00 is inputted from a digital pattern generator 2 to a D/A converter 1 to be measured, its output voltage A0 is given to a DC level reader 3, from which a corresponding digital data D0 is obtained and trsnsferred to a digital signal processing unit 4. In inputting a pattern 000-01 next, a digital data D1 is obtained similarly and transferred to the unit 4. Similarly, the pattern is being changed sequentially and up to a digital data Dn is obtained. The data D0-Dn obtained in this way are subject to Fourier transformation in the unit 4 and the data of the time axis is converted into the frequency axis data. Thus, the signal versus distortion factor characteristic, the frequency characteristic and the characteristic to the AC signal such as the input level characteristic are obtained. Further, the characteristic to the DC signal such as the linearity error and the differentiation linearity error is acquired.

Title: Operation control method of refrigerating plant
Inventor: TANAKA SHIGETO
IPC: F25D11/00
Filed: 1992-01-21
Abstract: PURPOSE:To carry out proper backup control when an inner temperature sensor of a refrigerating plant is out of order. CONSTITUTION:During operation in refrigeration mode, temperature sensors Thr and Thu inner temperature sensors detect the inner air temperature while a capacity control means 51 switches over the capacity of a compressor to a low value until the inner temperature reaches a specified temperature of around 0 deg.C whereas it switches over the capacity of the compressor to 100% when it reaches the specified temperature. When a failure discrimination means 52 discriminates the trouble of the inner temperature sensor Thr and Thu, a backup control means 53 operates a low capacity compressor for a specified time and when switches over the low capacity operation to a 100% capacity operation. This construction makes it possible to prevent an excessive rise in a pressure on a high pressure side and maintain the inner temperature to a specified low temperature, thereby enhancing reliability. In addition, it is possible to maintain the inner temperature around the setting value by carrying out intermittent operation ranging from 50% to 100% at a time interval equivalent to the setting inner temperature.

Abstract: PURPOSE:To control the rate of toner supply accurately by providing a means which emits a signal when there is no toner, a magnetic field generating member which shuts off a toner supply path magnetically, and a fixing member which moves a movable member in the direction moving apart from said supply path. CONSTITUTION:While there is a prescribed amt. of a toner 7 in a toner tank 1, the switch 10 of a sensor 10 is off and therefore no electricity is conducted to a magnetic coil 14, and a supply pipe 2a is magnetically shut off by the magnetic field from permanent magnets 18, 18', thus no toner is supplied to the tank 1. When the amt. of the toner 7 becomes short, the switch is turned on and a movable iron core 15 moves in the direction C, then the magnets move apart from the pipe 2a, and the toner is supplied. When the amt. of the toner 7 attains a prescribed amt., the switch goes off, and the electtic current to the coil 14 is shut off, whereby the iron core 15 is moved in the direction D and the supply pipe is magnetically shut off.

Title: High frequency device
Inventor: OTANI TADAYOSHI
IPC: H01L21/302
Filed: 1992-01-22
Abstract: PURPOSE:To realize a high frequency device capable of preventing the wear of a switch with a simple structure and stably switching high frequency to a plurality of loads for a long period. CONSTITUTION:When a load 5 is wanted to be applied to a high frequency, the capacitance of a variable capacitor 10 is maximized, and the capacitance of a variable capacitor 11 is minimized. As well known, the larger the capacitance of the capacitor, the lower the impedance, and conversely, the smaller the capacitance of the capacitor, the higher the impedance. Consequently, the impedance of the variable capacitor 10 whose capacitance is maximized is remarkably lowered, and the high frequency from an impedance matching equipment 9 is supplied to the load 5. On the other hand, since the capacitance of the variable capacitor 11 is lowered, the impedance of the variable capacitor 11 is remarkably increased, and the supply of high frequency to a load 6 is kept in the almost stopped state.
