IPC: G11B5/708
Filed: 1979-11-28
Abstract: PURPOSE:To smooth the magnetic layer, by selecting the binder and using the method to control the pitch of coarseness on the surface of two types of magnetic layers with the filler such as filler, abrasive, conductive powder or the like. CONSTITUTION:The maximum value is set to about >=80Angstrom (120-1,000Angstrom  preferably) for the mean coarseness (Ra) of the center line of the unevenness in the region where the pitch of surface coarseness of the magnetic layer is larger than about 300mum. On the other hand, the maxumum value is set to about <=40Angstrom (<=20Angstrom  preferably) for the coarseness (Ra) of the unevenness in the region of about 5-100mum pitch mentioned above. As a result, a suppression can be secured for the shaving of the magnetic layer, the thinning of the tape winding surface, the jamming and the wear of the head each.

These analog signals are converted by a binary circuit 10 into white image signals of logic 1 and black image signals of logic 0. A calculating unit 12 counts the number of 1 and 0 for each bit unit and compares it with the value of a memory unit 13. Since the compared values fail to coincide in case the pore get clogged or deformed, a warning is displayed in a display unit 14 to inform the operator of the test results.

Title: Amplifier for magnetic recording
Inventor: YAMAZAKI TSUKASA
IPC: H03F1/34
Filed: 1989-06-16
Abstract: PURPOSE:To make an output current constant by providing a bridge circuit network in which a potential difference across a resistor connecting to an output of a differential amplifier is independent of a voltage at a load terminal and proportional to an input voltage. CONSTITUTION:A voltage is caused with a current flowing to a load 6 across a resistor 5 and a bridge circuit network consists of resistors 1-4 and a differential amplifier 7. When the ratio of the resistance values of the resistors 1, 2 is equal to the ratio of the resistance values of the resistors 3, 4, the potential difference across the load 6 does not give effect on the potential difference across the resistor 5. Then an input signal 8 is multiplied by a multiple being a product between a voltage division ratio being the division of the resistance of the resistor 4 by the sum of the resistance values of the resistors 3, 4 and the gain being the division of the sum of the resistance values of the resistors 1, 2 by the resistance of the resistor 1, and the potential difference across the resistor 5, that is, the current proportional to the input signal 8 through the load 6 is obtained. Thus, the output current is made constant without increasing the output amplitude of the differential amplifier.

IPC: G06F9/06
Filed: 1984-07-27
Abstract: PURPOSE:To execute a timing processing without providing a timing memory corresponding to resources, and to curtail the memory quantity of the whole system by providing a registration buffer for a timing. CONSTITUTION:A registration buffer read-out counter (TMCNT) 1 is constituted so that it is driven by ''1'' whenever a release request is generated, and returned to ''0'' whenit reaches (m-1). Information of a word position of a registration buffer 2 pointed by the TMCNT 1 is fetched. Whether the fetched information is a resource number or not is decided, and if it is the resource number, it is released. A release request resource number generated newly in a word position pointed by the TMCNT 1 is registered. The TMCNT 1 is driven by ''1'' cyclically. That is to say, the resource number which receives a release request is registered cyclically onto the registration buffer 2, and the time for one period of the TMCNT 1 is secured as a prescribed time, by using this system.

Title: Retainer disposing structure of automatic transmission
Inventor: MIZUTA MUNEO
IPC: F16D25/0638
Filed: 1995-06-22
Abstract: PURPOSE: To improve the efficiency of operation like incorporation and restrain the increase of the number of parts by forcing a race of a bearing into an inner tube part to regulate the move of a retainer caused by the pressure from a returning means. CONSTITUTION: A forward clutch piston 21 is advanced leftward by the hydraulic action to connectively press a plurality of clutch plates 9 and rotate an internal gear member 29. When the hydraulic action is removed, the piston 21 is allowed to retreat rightward by a return spring 11 to release the press of the plate 9 and turn off a forward clutch 17, while the forward clutch piston 21 returns again to the original position and a press force of the spring 11 is caught by a retainer 23. This retainer 23 is regulated with respect to the move into an inner tube part by forcing a race 25 of a needle bearing 24 into the retainer. Thus a snup ring needed for the locking of the retainer 23 can be omitted to reduce the number of parts.

Abstract: PURPOSE:To obtain versatility and confidentiality of storage information by providing an FET having the 2nd gate electrode to which a word line and a bit line connected with the 1st gate electrode and drain electrode respectively are connected selectively by bringing the lines to a specific potential to at each cross position of the word lines and the bit lines. CONSTITUTION:In bringing the bit line 6 to a high voltage and the word line 1 to a voltage higher than a threshold voltage of the FET, when a gate electrode G2 is at a reference potential, the bit line 6 is not conducted to the reference potential and the bit line 6 is kept to a high potential. When the gate electrode G2 is not connected to the reference potential and the gate electrode G2 is connected to a gate G1, the bit line 6 is conductive to the reference potential and the bit line 6 goes to the reference potential. Further, when the gate electrode G2 is not connected to the reference potential nor the gate electrode G1, the gate electrode G2 is brought into the floating state, the potential of the bit 6 depends whether any electron exists on the floating gate or not and the presence or absence of the electron is selected optionally even after the completion of the array. That is, the bit line 6 keeps a high potential when the electron is injected to the gate G2, and when no electron exists in the gate G2, the gate goes to the reference potential.
