Title: Manufacture of one-transistor type dynamic memory cell
Inventor: NISHIMURA TADASHI
IPC: H01L21/8242
Filed: 1987-04-01
Abstract: PURPOSE:To prevent the occurrence of leaks and soft errors between memory cells effectively, by directly connecting a polycrystalline semiconductor layer, which is to become the storage terminal of one-bit memory capacitor, with a single crystal semiconductor layer, which is to become the source or drain region of an access transistor. CONSTITUTION:A first capacitor is formed with a high-concentration impurity region, a first insulating film 4, which is formed on the upper part of said region, and a polycrystalline semiconductor layer. A second capacitor is formed with the polycrystalline semiconductor layer, a second insulating film 24a, which is formed on the upper part thereon, and a low resistance layer. A memory capacitor (a) of one bit is constituted by the parallel capacitors of the first and second capacitors. Therefore, the sufficient memory capacitors are secured in a very narrow area. The polycrystalline semiconductor layer, which is to become the storage terminal of the memory capacitor, is isolated by the first insulating film 4 and directly connected to a single crystal semiconductor layer, which is to become the source or drain region of an access transistor (b). Thus, a structure, which is resistant to leaks and soft errors between neighboring memory cells, is obtained.

IPC: B24B23/03
Filed: 1997-02-24
Abstract: PROBLEM TO BE SOLVED: To eliminate continuous rotary traces, reduce pressure from a work and suppress generation of abrasion heat, without lowering processing capacity, by normally performing a rotary processing for the surface of the work in a circular-arc shape by a jig. SOLUTION: An eccentric cam 2 is mounted on a motor output shaft 1. A one-way clutch 4 is externally fitted to a drive shaft 5 journalled by a bearing 12. On the origin shaft side, that is, the external side of the one-way clutch 4, a driven element 3 is mounted. The eccentric cam 2 and the driven element 3 are fitted so that the driven element 3 may slide in a state that the driven element 3 is in contact with the eccentric cam 2. Thus, the continuous rotary motion of a first direction by the output shaft of the motor 1 is converted into a first direction pitching rotary motion at a fixed angle within 90 deg. and a free rotary motion of a second direction and surface working is performed for an object by a jig of the drive shaft 5.

Title: Instantaneous power interruption detecting circuit of air conditioner controller
Inventor: HAYATA YOSHIKI
IPC: F24F11/02
Filed: 1986-04-11
Abstract: PURPOSE:To prevent an erroneous action emitting an alarm at the time of an instantaneous power interruption by providing a device for constantly monitoring a commercial power supply in an air conditioner controller, and clearly discriminating a normal operation of a safety device from OFF of an electromagnetic switch for a compressor during an instantane ous power interruption. CONSTITUTION:A time t1 during which an output of a comparator 12 at an ordinary time becomes low 'L' is smaller than a period T. The output of the comparator which becomes 'L' every period T is inputted through an input terminal 18 of a microcomputer 6, and when a power supply to the comparator is OFF for a time represented by t2, the output of the comparator is remains to be 'L' for t2 second. When the output from the interrupt input terminal 14 of the microcomputer 6 is changed from 'H' to 'L', whether the input 'L' time of the terminal 18 is longer or shorter than the period T at the ordinary time is judged. When the 'L' time is longer than the period 'T' it is judged to be a temporary erroneous input due to a power interruption, and a compressor is once stopped. Thereafter, the operation of the compressor is automatically resumed. In the case of 'L' time being longer than the period T, it is judged to be due to the operation of the safety device, the operation of the apparatus is stopped and is put into an alarm condition.

The output of this element 48 is passed through a preamplifier 50 and detected synchronously by a synchronous detector 54 which receives the angular frequency omegam of the modulator 44 from an oscillator 56. The output passed through the amplifier 50 is detected synchro nously by a synchronous detector 60 with an angular frequency 2omegam from a frequency multiplier 58 and compared with a zero level by a comparator 62, and an oscillator 56 makes an adjustment with the amplitude of the angular frequency omegam of the modula tor 44 so that the input difference signal is zero.

Title: Gain control circuit
Inventor: SUZUKI HARUO
IPC: H03G1/00
Filed: 1980-06-17
Abstract: PURPOSE:To exercise wide-range gain control by varying the gain of a differential amplifier through diodes, whose conduction resistance vary with an AGC voltage, for the intermediate-frequency gain control of an IC-impelemented AM radio set. CONSTITUTION:An AGC voltage obtained from an AGC voltage circuit 2, which controls the gain of the intermediate-frequency amplification stage of an IC-implemented AM radio flows from a current-source transistor (TR)T6 to a suction TRT7 through a middle point (a) between diodes (d)1 and 2 and another middle point (b) between Ds 3 and 6. Conduction resistances of the D1-D4 vary with the current flowing through the TRT6. Those D1-D4 are connected between input terminals of TRs T1 and T2 constituting a differential amplifier. Therefore, when the  conduction resistances of the D1-D4 are nearly zero, the gain is zero and when extremely large, on the other hand, the largest gain is obtained. Thus, wide-range  gain control is exercised.

Title: Instruction prefetching method
Inventor: MURATA YOSHIO
IPC: G06F9/38
Filed: 1986-04-11
Abstract: PURPOSE:To always prefetch either a single word length instruction or a double word length instruction at a high speed by dividing a main memory part into even and odd address parts and also using plural selectors and instruction registers. CONSTITUTION:A main memory part is divided into an even address part 1a, and odd address part 1b and an even address part 1c and at the same time the instructions of three words are read out. Therefore a selector 6a selects a read instruction out of the part 1a and sends it to a host instruction register 3a as long as the instruction that is presently read out has an even address. While a selector 6b selects a read instruction out of the part 1b and sends it to a lower instruction register 3b is the instruction that is presently read out has an even instruction. An instruction decoding part 4 decides by decoding whether the instruction fetched by the register 3a has the single word length or the double word length and then issues a command to a CPU 5 sends the address of the instruction to be executed next. Thus an instruction is always prefetched at a high speed regardless of the single or double word length.

Abstract: PURPOSE:To confirm visually an ON or OFF state by illuminating a display means with the light whole optical path is changed by an optical path selecting means provided into an optical path reaching a photodetecting means from a light emitting means. CONSTITUTION:The beams produced by light emitting means 17a-17e reach photodetecting means 5a-5e; while the beams produced by light emitting means 18a-18e reach light emitting means 6a-6e respectively. The switches SW1-SW25 are provided in a matrix form at the intersecting points of the beams crossing or orthogonal with each other. When a switch SW7, for example, is pushed vertical to the surface of a form, a light beam B1 is cut off by the switch SW7. While the optical path of a light beam B2 is changed to a front position vertical to the form surface by a mirror. Thus the reflected light enters the eyes of an operator and the operator can confirm that the SW7 is kept in an ON state.
