Title: Water-proof solid spot washing cloth
Inventor: NAKATANI TAKAMI
IPC: D06F35/00
Filed: 1994-11-24
Abstract: PURPOSE: To precisely wash only soiled portion of clothing while keeping the other portions from getting wet by using a water-proof cloth provided with an opening in its center, around which an elastic string is passed, whereas only a portion of the clothing soiled with food stains is pulled out and tied with the string. CONSTITUTION: In manufacturing the subject cloth, the center of a water-proof cloth 1 formed in circle is first cut out round to make an opening 2. Then, a loop into which an elastic string 3 is passed through is made around the opening 2. The loop is made by using a patch cloth, rather than by making a lapel. The elastic string 3 attached with a clasp 4 is passed through the opening 2. Then, a seam 5 is sheared at the elastic string to give elasticity to the entire cloth 1. In using the cloth, the opening 2 and the loop are put onto a soiled portion of the clothing, and the elastic string 3 is pulled to tie the soiled portion of the clothing, the string being engaged into the clasp 4. Then, the cloth 1 is turned over, fitted onto the clothing, and the portion soiled by food stains is taken out from the opening 2 for precise spot washing.

Title: Rotary head type magnetic recording and reproducing device
Inventor: YOSHIO HIDEAKI
IPC: G11B15/61
Filed: 1987-12-25
Abstract: PURPOSE:To completely prevent the reproducing image from being bent in shape and color slurring by winding a magnet tape around a rotary drum in such a winding method of overlapping at a specified angle. CONSTITUTION:The rotary drum 4 with a pair of rotary video heads 2a and 2b and a pair of rotary audio heads 3a and 3b, wound with a magnetic tape 1 is rotated in the direction of an arrow A. In this case, the winding of the magnetic tape 1 to the rotary drum 4 is performed in the overlapping winding at the angle corresponding to a tape length of approximately 0.5 times as long as a vibratory wavelength of magnetic tape vibration generated by shocking at the time of bumping into and separating from the magnetic tape 1 against a rotational angle for forming one field image of the rotary heads 2a, 2b, 3a and 3b. By this method, the vibration of the magnetic tape 1 is attenuated, and even when a compatible reproducing is performed between different VTRs in the number of rotary heads, the bend and color slurring of the reproducing image is scarcely generated so that the excellent reproducing image quality can be obtained.

Title: Magnetic disk device
Inventor: NISHIMURA MAKOTO
IPC: G11B21/10
Filed: 1989-12-20
Abstract: PURPOSE:To improve the suppression rate of a position deviation by inputting a position deviation signal to a position deviation correction circuit and adding a correction signal outputted from the position deviation correction circuit to a position deviation generating circuit. CONSTITUTION:A position deviation correction circuit 15 consists of a closed loop circuit 16 and a proportion element 17. A dead time element 18 is provided so as to apply positive feedback of the output to the input side. The element 18 delays a position deviation E(S) by a disk fundamental rotation period L and outputs the result. Since the output of the element 18 is fed back positively to the input side, the open loop gain is infinite at a frequency k/L being a multiple of (k) of a disk rotation frequency 1/L. The element 17 outputs a signal at a multiple of K of an input signal. Thus, the suppressing rate of the control is improved by nearly 50 - 60dB.

A nitride film 5 is formed on the oxide film 4, and an opening 7 and an opening 8 for connection that are formed by etching the nitride film 5 are a part that becomes source, drain, and channel regions 14, 15, and 11 of a MOS transistor and a part that becomes an LOCOS 9 for connection between a part that becomes a substrate contact region 12. While the openings 7 and 8 are formed at the nitride film 5, the oxide film is thrown to a thermal oxidation furnace, thus forming a LOCOS 13 and a LOCOS 9 for connection. After the LOCOS 13 and the LOCOS 9 for connection are formed, the nitride film 5 is eliminated, further an oxide film at a part other than the LOCOS 9 is completely eliminated, thus forming a gate oxide film 23.

Filed: 1999-11-22
Abstract: PROBLEM TO BE SOLVED: To provide a method of starting a multi-stage compression system and the multi-stage compression system capable of preventing a propagating stall without complicating the system. SOLUTION: A method of starting a multi-stage compression system comprises the steps of starting a first compressor 5 and a second compressor 7 in parallel state, leading a part of the discharged gas from the first compressor 5 gradually to the suction side of the second compressor 7 so as to reduced the final amount of gas from the first compressor 5, shutting off a passage 10 for the discharged gas when the final discharged gas amount becomes zero, leading all discharged gas from the first compressor 5 to the suction side of the second compressor 7 so as to operate the first compressor 5 and second compressor 7 in series.  First the first compressor 5 and second compressor 7 are operated in parallel with each other so that a total pressure ratio is reduced (namely, aerodynamic mismatch is lowered) so as to suppress a propagating stall, and then the first and second compressors 5 and 7 are coupled in series to each other so as to realize a two-stage compression system. Thus, a swing stall at the start can be prevented without complicating a system such that the compressors 5 and 7 are modified into variable pitch types.

Title: Line duplicating terminal device
Inventor: IIDA HIROYUKI
IPC: H04L1/22
Filed: 1987-12-29
Abstract: PURPOSE:To confirm that a dedicated line is abnormal and after that, to switch the line when there is an incoming from a public line by providing a timer having a timer time longer than the polling period of the dedicated line and resetting this timer for every polling from the dedicated line. CONSTITUTION:The device is provided with a timer 2 having the timer time longer than the polling period of the dedicated line to be resetted by a polling signal from the dedicated line. When the dedicated line is normal, the timer action of the timer 2 is reset every time the polling is received and even when there is the incoming from the public line during this, a switching signal generating part 3 does not generate a switching signal. When a trouble is generated in the dedicated line and in the polling of constant periods is not received, the timer 2 becomes time-up and at this time, when the polling is applied from the public line, the switching signal is generated and a line switching part 1 is switched. Thus, the switching at the time of getting the incoming from the public line when the dedicated line is normal can be prevented.

IPC: H03G3/10
Filed: 1987-12-25
Abstract: PURPOSE:To more increase the maximum amplitude of an output signal at the time of applying a prescribed voltage and to make an output DC operating point constant by adding a 3rd branch means and a constant current source to a conventional circuit and adopting the opposite application method of a gain control signal to the 3rd branch means to that in 1st and 2nd current branch means. CONSTITUTION:A differential pair 2 branches a constant current (I1) from a 1st constant current source 1 into 1st and 2nd currents in response to an input signal. 1st and 2nd current branch means 3, 4 branch respectively 1st and 2nd currents in response to the inputted gain control signal. A 3rd current branch means branching a constant current (I2) from a 2nd constant current source 6. A gain control signal is fed to resistors R4, R5 to the branch means 3, 4 but applied to the branch means 5 to the opposite terminal of the resistor R5. When the inputted gain control signal increases, the current flowing to the resistors R4, R5 increased, but the current flowing to the resistor R5 is decreased and the output DC operating point is not fluctuated. Then the voltage applied to the resistors R4, R5 is increased by the collector-emitter voltage (VCe) and the maximum amplitude of the output signal is more increased.
