Patent JP-H09171689-A (JP)
Title: Semiconductor integrated circuit
Inventor: MARUYAMA AKIRA
IPC: G11C11/417
Filed: 1995-12-20
Abstract: PROBLEM TO BE SOLVED: To obtain a control circuit which can reduce the current consumption of an SRAM(static RAM) at its writing operation time and enables stable writing operation. SOLUTION: When a memory cell 1 is written, a word line potential WL1 goes up to H and then an Nch transistor(TR) 40 in a word line potential detecting circuit 46 turns on; and a bit line potential XBL1 goes up to L and then a Pch TR 34 in a bit line potential detecting circuit 39 turns on. Consequently, a write signal goes up to H, an output signal 46 varies from L to H, and an output signal 39 varies from L to H, so an output signal 47 falls from H to L and an output signal 51 also falls from H to L. Consequently, the word line potential WL1 falls from H to L and the bit line potential XBL1 rises from L to H, thereby stopping the writing operation of the memory cell 1. Simultaneously with the end of the writing to the memory cell 1, the writing operation stops, so the current consumption is reducible.

Title: Magnetic clamping structure for disk device
Inventor: TANAKA TOSHIYUKI
IPC: G11B17/028
Filed: 1987-12-26
Abstract: PURPOSE:To make a disk device compact by providing an elastic protruding part in a turn table and a fitting recessing part in a center hub. CONSTITUTION:A central hole 7a of a center hub 7 is inserted to the tip of a revolution driving shaft 3. Then, when it is inserted so that the lower surface of an optical disk 1 can be abutted on a device surface 4a of a turn table 4, the magnetic force of an adsorption magnet 5 sucks the hub 7 of a magnetic substance and the disk 1 is adsorbed to the surface 4a. Since claws 6a and 6b of nonskid metal fittings 6 and a locking hole 7b of the hub 7 are on a same circumference, the claws 6a and 6b are pressed to the lower edge surface of the hub 7 or fit to the hole 7b. In case of being pressed, since the magnetic force of the magnet 5 is weak, when the table 4 is accelerated by the activation of a spindle motor 2 and the claws 6a and 6b are fit into the hole 7b. Thus, since the adsorption force of a magnetic device can be made small, the device can be miniaturized.

Inventor: UEMATSU KATSUNOBU
IPC: B65G11/00
Filed: 1990-11-29
Abstract: PURPOSE:To prevent shock and clogging caused by the fall of large lumps in a conveyor transfer device for highly adhesive material with large lumps mixed therein by providing a first grade adjustable baffle plate and a pair of baffle plates, disposed opposedly and oscillatingly by vibration absorbing means on the downstream side of the first baffle plate, between an upstream and an downstream conveyors. CONSTITUTION:Material falling into a shoot 2 from an upstream conveyor 1 hits a first baffle plate 3, falls while being rebounded and hits a second baffle plate 5. At this time, falling energy is sucked by a spring 7a to reduce the fall speed. The material sprung by the baffle plate 5 hits a third baffle plate 6 and its speed is reduced receiving the same action. The material thus reduced in its speed falls, with small impact, onto a downstream conveyor 9. The gradient of the first baffle plate 3 is adjusted by a gradient adjusting device 4 to prevent material falling directly onto the downstream conveyor 9.
