Filed: 1984-06-21
Abstract: PURPOSE:To decrease entirely replacement work of a magnetic tape in checking work of an erasure head by forming sequentially plural magnetic recording layers having different magnetic characteristic for required numbers in the lengthwise direction of a tape. CONSTITUTION:A normal magnetic recording layer 9 made of gamma type ferric oxide, a chromium magnetic recording layer 10 made of a gamma type ferric oxide and a metal magnetic recording layer 11 made of iron are formed on the surface of a tape 1a made of a synthetic resin in the magnetic tape 1 in the lengthwise direction of the tape 1a while inserting a nonmagnetic region 12 respectively among them. The length of the magnetic recording layers 9-11 is a length required for the check of one erasure head, and in general it is nearly 150-300mm.. Since the nonmagnetic layer is inserted among the magnetic recording layers, the change in the magnetic recording layers is detected not only electrically but also visually.

Title: Track counting circuit
Inventor: KATO TADASHI
IPC: G11B21/08
Filed: 1989-05-22
Abstract: PURPOSE:To prevent the erroneous binarization caused by the fluctuation produced in a low speed area by setting the tracking error signals at different output levels between the high and low speed areas. CONSTITUTION:A comparator 9 is connected to an arithmetic circuit 2 and binarizes a tracking error signal to output it to a counter 5. The resistances 10 - 12 decide the hysteresis of the comparator 9, and a switch 13 turns on and off the resistance 11 to switch the hysteresis level. A buffer 14 is connected to a speed sensor circuit 4 and drives the switch 13, and the switch 13 is kept turned on in a low speed area. The comparator 9 has the large hysteresis width owing to the connection of the resistance 11. Meanwhile the switch 13 is kept turned off in a high speed area, and the hysteresis width of the comparator 9 is decreased. In such a way, the reference of the binarization level rises up in a low speed area owing to the large hysteresis width of the comparator 9. As a result, the fluctuation of the tracking error signal is never binarized.

Title: Ignition distributer
Inventor: ARANO ISAMU
IPC: F02P7/00
Filed: 1981-08-14
Abstract: PURPOSE:To make it possible to detect engine rotation without increasing the height of a distributer by obtaining the ignition timing of an electronic fuel injection system from the output of a rotary angle detection unit of a weight base for a centrifugal type advance angle unit. CONSTITUTION:A movable base 5, connected to a negative pressure responding unit 2, is mounted in a distributer housing. On the movable base 5 are fixed a magnet 6 and a stator core 7. When the clearance between the core 7 and a reactor 13 varies due to engine rotation, a signal voltage is generated in a detection coil 8 and an injection timing control unit 9 operates, thereby determining ignition timing. A detection unit 17, comprising a core 171, a magnet 172, a core 173, and a detection coil 174, is installed at a position which faces a weight base 14 integrated with a shaft 11. The detection unit 17 detects the rotary angle by means of the convex portion of the weight base 14. This signal is used to determine fuel injection timing. Therefore, if a distributer is built-in after adjusting the ignition timing in relation to the reference cylinder, the fuel injection  timing can be also automatically set.

The second end could be the mirror image of the first end or could be any fitting desired to be attached to a tube section. The first end has a constant radius annular chamber such that the end of a tube section slides easily therein initially. The exterior of the first end of the sleeve has a "REVERSE TAPER" configuration such that the exterior radius of the sleeve is least near the center portion and increases generally outward therefrom to a maximum near the end of the sleeve. When the lockring is forced onto the exterior of the sleeve, the sleeve and tube section are deformed the least amount near the center portion, the amount of deformation than generally increasing outward therefrom to a maximum near the end of the sleeve. In the preferred embodiment, this reverse taper is accomplished by a single exterior rib having an inclined surface running therefrom toward the center portion. In another embodiment, the reverse taper is accomplished by a plurality of externally projecting ribs, the first rib near the end of the sleeve being of the greatest radius, and each successive rib toward the center of the apparatus being of successively smaller radius.

Abstract: PROBLEM TO BE SOLVED: To attain the reduction of power consumption by applying a structural level to all gates on a logic circuit and replacing an operating voltage. SOLUTION: An input means 100 inputs respective instructions. A level applying means 210 applies the structural level to all the gates on the logic circuit. Then, an operating voltage replacing means 220 tries the replacement to the low power supply voltage (VDDL) gate successively from the standard power supply voltage (VDDH) gate at the low structural level and when a timing limit is satisfied, a level converter is inserted as needed while replacing such a gate to the VDDL gate. Namely, the strutural level is applied to all the gates corresponding to the number of steps from a register gate or an external output port, and the replacement to the VDDL gate is tried successively from this gate at the low structural level. Further, a VDDL area returning means 230 returns a VDDL area, which is not contributed to the reduction of power consumption, to a VDDH area.
