Title: Recording system for magnetic disk
Inventor: MIWA TAKAHIRO
IPC: G11B20/14
Filed: 1987-05-13
Abstract: PURPOSE:To increase a recording capacity and to simplify a control circuit for the reading of the data by recording significant data with a converting code group, and recording the synchronizing signal part with a code in which 1 is continuous and the last is completed by 0. CONSTITUTION:An effective data part 10 is converted and recorded to a code including clock information in which two or more of zeros are not continuous. Consequently, the number of bits distributed for a clock only is decreased and a recording density can be increased. Since synchronizing signal parts 6 and 9 are codes in which 1 is continuous and the last is completed by 0, it can be discriminated that the synchronizing signal parts 6 and 9 are obtained by the continuity of 1, thereafter, it is detected next that 0 is expressed and the timing of the starting of the data can be easily detected. Thus, the starting of the data may detect the signal of one bit, and for that reason, a control circuit is simplified. The data density is increased while a margin is secured and the boundary between a data area and a gap can be clearly classified.

Filed: 1998-04-27
Abstract: PROBLEM TO BE SOLVED: To enhance the working precision without increasing the electric discharge area to the progress of electric discharge machining by providing a disc-like electrode and a moving mechanism for moving both a rotating mechanism and a feed part. SOLUTION: A disc electrode 8 is moved in an arrowed direction 6, which is the thickness direction of a workpiece, by the operation of an electrode feeding motor according to the cutting speed of the workpiece. After the cutting of the workpiece by the disc electrode 8 is progressed, and the tip of the disc electrode 8 pierces through the workpiece, the movement of the disc electrode 8 in the arrowed direction 6 is stopped. A machining head feeding motor 20 is then operated to move a machining head 1 in the longitudinal direction laid along the workpiece of an arrow 22. Thus, the disc electrode 8 continuously and quickly cuts the workpiece in the state having high electric discharge machining performance in the longitudinal direction to smoothen the cut surface of the workpiece 7.

Title: Digital signal processor
Inventor: ITO AKIHIRO
IPC: H03H17/04
Filed: 1995-04-19
Abstract: PURPOSE: To provide a digital signal processor for which its configuration is simplified and accuracy is improved. CONSTITUTION: Since the word length of data is extended by multiplication when calculating the coefficient of a filter, ordinarily, the word length of data is returned to a prescribed word length by a method such as rounding or omission. An arithmetic error is generated at the conventional device as a result of processing but data to be this error component are stored in a data preparing means 5 and these data can be outputted as auxiliary data Dh. These auxiliary data Dh are added in the next step inside a cyclic digital filter 3 so that the enlargement of error can be suppressed and high arithmetic accuracy can be provided by adding a little processing and parts. Besides, the degradation of ordinary response characteristics caused by rounding or omission can be prevented and ordinary gain = 1 can be guaranteed.

Abstract: PURPOSE:To prevent temperature in the device from rising caused by heat generated by a fixing device after the device is used in the image forming device provided with the fixing device which fixes a toner image on a transfer sheet by heating and pressing it. CONSTITUTION:This device is composed of the fixing device 13 where a heat insulating shutter 20 having a shutter part 20a is rotatably supported on a rotary supporting shaft 22 provided on both side plates 21 of the fixing device 13, and which is provided with the heat insulating shutter 20 formed by providing a weight 20b at the facing position of the shutter part 20a so that the shutter 20 may act so as to close the aperture part of the fixing device 13 formed by an entrance guide 17 and a stay 23 when the device is placed lengthwise and housed after it is used. Since the position of the shutter 20 is switched by interlocking with the action when the device main body is made to stand, the temperature in the device is prevented from rising caused by the heat generated by the fixing device even when the device is made to stand and housed immediately after it is used.

Abstract: PURPOSE:To prepare a molded product unified with a thermosetting or thermoplastic resin in an inseparable manner by together using an injection molding machine remodeled in its sequence so as to perform special operation and a mold having a structure provided with a special part operated by a spring or hydraulic pressure. CONSTITUTION:An injection molding machine capable of performing operation injecting a necessary material under low pressure in such a state that a mold is not perfectly clamped and clamping the mold immediately thereafter under high pressure is used. The mold has a straight part 10 and this part is matched with the shoulder part of a protruding part 3. Therefore, a metal foil is not cut in such a stage that the mold is not perfectly clamped but cut when the mold is perfectly clamped. A slide part 4 is mounted to the outer peripheral part of the protruding part 3 and always given upward push-up force by a spring or a hydraulic or pneumatic pressure cylinder 5. Therefore, the slide part 4 is pushed upwardly when the mold is opened and pushed down to the lowermost position at the time of clamping. At this time, the straight part 10 of a fixed mold is registered with the shoulder part of a movable mold.

Title: Heat storage hot air heater
Inventor: ATSUMI TORU
IPC: F24H7/02
Filed: 1998-04-27
Abstract: PROBLEM TO BE SOLVED: To ensure a specified heat storage quantity in a short time by controlling an on/off heater within a preset temperature stored in a memory means while being switched for every input signal thereby eliminating shifted heating of a heat accumulator. SOLUTION: A control means 6 controls a heat accumulator 1 within a temperature range of 500 deg.C-600 deg.C by controlling conduction of an on/off heater stored in a memory means 9 while being switched for every input signal after first and second heaters 7, 8 are turned on in response to a heat accumulation signal and the heat accumulator 1. Shifted heating is suppressed as compared with a case where the heat accumulator 1 is heated only with a single heater of 600 W and heat accumulation can be finished at double speed because a 1200 W heater is employed. Furthermore, lifetime of the components of the control means 6 can be prolonged because burden on the control means 6 is averaged at the time of on/off control of each heater.
