Title: Storage device
Inventor: IZUMO SHIGEKI
IPC: G11C11/34
Filed: 1987-09-29
Abstract: PURPOSE:To reduce power consumption by providing a refreshment control circuit and a control circuit executing a normal memory access on a storage device using a DRAM array and independently operating them. CONSTITUTION:When the storage device is normally used, power source is supplied to the whole circuits in the device and the whole operation requested to the storage device is executed. When a refreshment request is given from the outside through a control line 24 now, a RAS (a row address strobing) signal 1 for operation, a column address strobing (a CAS) signal 1 are generated by the refreshment control, circuit 22 and supplied to the DRAM array 21 through OR gates 26 and 27 as they are. Besides, when an address and an access request are given from the outside through an address/control line 25, normal signals RAS 2 and CAS 2 are generated by an access control circuit 23 and supplied to the array 21 through the OR gates 26 and 2 in the same way. Thus, the refreshment operation is stopped in a memory content maintaining term.

Title: Ribbon lifting mechanism for printer
Inventor: YASUDA HIROSHI
IPC: B41J35/23
Filed: 1985-11-01
Abstract: PURPOSE:To improve the printing quality by suppressing a vibration generated at a ribbon holder due to the contact of a stopper lever with the connector of the holder when the holder momentarily moves from the first position to the third position. CONSTITUTION:If the second solenoid 26 is operated when a ribbon holder momentarily moves from the first position to the third position, an operating rod 29 is projected, and one end of a stopper lever 33 is lifted. Then, the lever 33 moves a supporting shaft 33a along a long hole 32 and rotates with the shaft 33a as a center, its bent portion 35 moves in conjunction with the operation of the solenoid 26 and rotates. Then, the timing for separating the lever 33 from a connector 22 is accelerated so that no delay occurs in the rotation of the holder 20. Accordingly, the movement is not interfered due to the contacts of the bent portion 35 with the connecting pawls 23, 24 of the connector 22, and the lever 33 can be separated from between the pawls 23 and 24. Thus, it can prevent the holder from vibrating to improve the printing quality.

Title: Permanent magnet having flat plate multipolar anisotropy and actuator
Inventor: SHIMIZU MOTOHARU
IPC: H01F1/08
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To remarkably improve torque by forming a plurality of magnetic poles on a flat surface and allowing at least two adjacent magnetic poles of flat plate magnetic poles to have polar anisotropy. SOLUTION: After an R-T-B alloy is pulverized roughly, material powder is made by fine pulverization using a jet mill. Next, after the material powder is filled in a flat plate cavity, while an orientation magnetic field is applied, which energizes an oblate ellipsoidal coil formed on the side of an upper punch and provides the cavity with flat plate bipolar anisotropy, compression molding is carried out by the upper punch and a lower punch. An obtained compact undergoes sintering, cooling, and machining to a predetermined size. And then, the compact is heated and cooled. Consequently, it is possible to obtain a flat plate multipolar anisotropy sintering magnet, in which an R2T14B intermetallic compound (R is at least one of rare earth elements including Y, and T is Fe or Fe and Co) is a main phase and two magnetic poles 21 have polar anisotropy.

Title: High-frequency hybrid integrated circuit
Inventor: DEGUCHI KAZUHIDE
IPC: H01L27/13
Filed: 1986-10-15
Abstract: PURPOSE:To obtain a high-frequency hybrid integrated circuit, wherein a frequency characteristic is not found in effective capacitance and loss is less, by connecting the grounding electrode of a capacitor to the common metallized layer of a transistor. CONSTITUTION:A common metallized layer 9 is grounded to a radiating fin 1 through a metallized side surface. One end of a chip capacitor 8, whose other end is connected to a conductor layer 5, is connected with solder and the like. The chip capacitor 8 is connected to the common metallized layer 9 of a high- frequency, high-output transistor 2 directly. Therefore, the effect of the parasitic inductance Lp of the chip capacitor 8 is hardly received. Thus a frequency characteristic is not found in effective capacitance Ce. Since the loop of a high frequency current to an emitter becomes smaller, a parasitic resistance component rp also becomes smaller and almost equal to the effective capacitance Q of the chip capacitor 8. Thus loss is not yielded.
