Title: Magnetic recording and reproducing device
Inventor: YONEDA YASUHIRO
IPC: G11B27/10
Filed: 1985-08-02
Abstract: PURPOSE:To correctly demodulate an ID signal even during FF/REW time, and to facilitate the high speed retrieval of a digital sound signal by controlling the rotating frequency of a cylinder correspondingly to tape speed detected by a prescribed operation and making the relative speed of a tape and a rotary head equal to that during a normal reproduction. CONSTITUTION:The sum of rotating cycles of S, T reels 13, 14 operated by an adder 3 during recording, namely Ts(1)+Tt(1) is stored in a constant memory 5. Then, in FF/REW, a value similarly operated in the adder 3, Ts(n)+Tt(n) is inputted to a velocity arithmetic unit 4, in the velocity arithmetic unit 4, the operation of a double speed ratio (n) of the sum of the rotating cycles is performed, and the double speed ratio (n) is outputted to a ROM data 6 and to a cylinder control circuit 18. As mentioned above, from the cycles of both the S, T reels, the double speed ratio (n) is obtained, if the rotation of the cylinder is controlled to a rotating frequency operated by (n), even when the tape speed is changed, the relative speed between the tape and a rotating head is kept constant, namely, the relative speed during recording or during a normal reproducing can be maintained.

Title: Control circuit of automatic vending machine
Inventor: HARA SEIJI
IPC: G07F9/00
Filed: 1995-06-14
Abstract: PURPOSE: To automatically perform a time shift control by generating virtual time data for indicating the time obtained by shifting the time by a time difference indicated by time difference data and performing time control. CONSTITUTION: This control circuit 1 performs the time control when the interruption of the respective parts of an automatic vending machine is not generated. A processing means 2 generates the virtual time data for indicating the time obtained by shifting the time from the time indicated by present time data or prescribed time data by the time difference indicated by the time difference data, uses the virtual time data instead of one of the time data and performs the time control of shifting a prescribed time by the prescribed time difference. This, even when the control of shifting a prescribed time by a prescribed time difference is required, only inputting the prescribed time difference without resetting prescribed data is sufficient for the purport, efficiency is improved by the reduction of man-hour and the time at the time of setting such as resetting and quality is improved.

Abstract: PURPOSE:To shorten the whole length of a mover without increasing the stress of a plate spring by a method in which a recessed notch is provided in the longitudinal direction of the plate spring, and an operator is fixed to the recession of the notch by one-spot welding. CONSTITUTION:In the mover of a printing head in which an operator 18 is welded to a plate spring 19 for fixation, the whole length of the mover is shortened by the length L6 of the recessed notch 20 of a plate spring 18.

No variation in the length L4 of the recession of the spring 19 occurs. The whole length of the mover can be shortened, and the outside diameter of printing head can be reduced without increasing the stress of the plate spring 19.

Title: Fur remover
Inventor: MASUDA TERUO
IPC: A47K3/00
Filed: 1991-07-15
Abstract: PURPOSE:To facilitate the removal of fur for bathing water by connecting a suction head to a gas supply pipe to a jetting nozzle through a bellows hose to be provided with a float body and a filter in the apparatus so arranged that the bathing water is jetted into a bath tub from the jetting nozzle together with bubbles. CONSTITUTION:Normally, while a suction head 3 is fitted into an opening 6 of a receiving cylinder 15 mounted on a flange part 5 of a bath tub 4, a gas is sucked into a gas supply pipe to a jetting nozzle which jets out a gas-liquid mixed water into the bath tub and jetted into the bath tub together with a bathing water.

Title: Scroll compressor
Inventor: MIZUNO TAKAO
IPC: F04C18/02
Filed: 1984-08-22
Abstract: PURPOSE:To ensure pressure of supplied oil through a wide operating range by connecting a middle pressure chamber to the low pressure side of a compressor when a pressure of oil which is discharged from the discharging part of said compressor is below a specific value, and connecting the middle pressure chamber to the high pressure side thereof when a pressure is over said value. CONSTITUTION:At the starting time, a pressure inside a compressor is balanced so that a spring 16 keeps pressing the valve body 15 of a valve device 13 to contact a stop ring 17. In such state, a pipe 18 and a primary port 19 are connected to each other and a middle pressure chamger 8 is connected to the low pressore side of a compressor 2. When a discharge pressure is increased over a specific value after the starting, discharge pressure which acts on one end face 15a of the valve body 15 overcomes the spring force of the spring 16. The valve body 15 is then slided to a position as shown in the drawing, having a seat part 15c close a primary port 19 and connecting a pipe 18 and a secondary port 20 to each other via ring-like groove 15d and a valve hole 15e. The middle pressure chamber 8 is therefore connected to the high pressure side of a compressor part 2. Through such operation, oil supply pressure (differential pressure between discharge pressure and middle pressure) can be ensured constantly and the operating range be widened by the improvement of oil supply.

Abstract: PROBLEM TO BE SOLVED: To obtain a digital protection relay functioning surely in response to a failure in a transformer by blocking the output from a differential protection element using the output from an excitation inrush current countermeasure element having means for delaying the reset of the output from a decision means by a specified time thereby preventing the differential protection element surely from acting with the excitation inrush current of the transformer. SOLUTION: A differential relay 1 comprises an amplitude operating section 21, a flatness deciding section 22, a reset delay timer 23 and an excitation inrush current countermeasure element 61. A differential current Id operated at the differential current operating section 14 of a differential element 5 is introduced to the excitation inrush current countermeasure element 61 and the amplitude J is determined at the amplitude operating section 21 by performing an operation for detecting the amplitude. When it is lower than a specified value k, the flatness deciding section 22 produces an output.  On the other hand, output from the reset delay timer 23 is inverted through a NOT operating circuit 19 and ANDed, through an SND circuit 20, with an output from the differential element 5 in order to block the output from the differential element 5 operating with an excitation inrush current thus preventing erroneous action of the differential relay 1.
