Patent JP-H02184720-A (JP)
Title: Optical system encoder for disk device
Inventor: TAMAYAMA RYUZO
IPC: G11B21/08
Filed: 1989-01-11
Abstract: PURPOSE:To prevent the deviation of phase of detection output caused by the change of temperature by dividing the phases of plural slit patterns and photodetector parts opposed to the slit patterns into two respectively and symmetrically distributing them to both ends in the rocking direction of a scale. CONSTITUTION:Four phases A, A', B, and B' of each pair out of four slit patterns 12a of a reticle 12 and four photodetector parts 13a of a photodetector 13 opposed to the slit patterns 12a are divided into two respectively and eight divided phases A/2, A'/2, B/2 and B'/2 are symmetrically distributed to both ends in directions shown by arrows (b) and (b') which is the rocking direction of the scale 11 by setting a reticle center P as a center. In the photodetector part 13a, the same phases of the divided phases are mutually connected through electric wirings E1-E4. When the temperature is high, the phase of the right output of the A/2 advances and that of the left output of the A/2 is delayed with respect to the phase B because of the positional deviation to a y-axis direction of the reticle 12. Then, the synthetic output of both of them becomes a trapezoidal wave and the detection output A which is sufficiently large for the reference voltage V of the detection output is obtained.

Title: Motor controller
Inventor: NAKATANI MASAJI
IPC: H02P6/08
Filed: 1999-01-12
Abstract: PROBLEM TO BE SOLVED: To provide a motor controller which can realize highest-efficiency operation of an IPM motor for which optimum conducting phase, in which the power supply current becomes the smallest, dynamically changes from moment to moment depending upon the rotating condition of the motor, such as number of revolutions, torque, etc., by aggressively searching the optimum conducting phase. SOLUTION: A conducting phase setting means 7 sets a conducting phase value at every specific, so that the efficiency of an IPM motor 1 is highest. At setting of the conducting phase value, the means 7 compares the preceding current value and set conducting phase value with the present current value and set conducting phase value and sets the new conducting phase value, based on the compared results. A conduction distributing means 8 decides the conducting timing of the motor 1, based on the thus set conducting phase value and the phase detected by means of a rotor phase detecting means 5, and the motor 1 is driven.

Patent JP-S59132218-A (JP)
Title: Switched capacitor
Inventor: YAMAMOTO KAZUNARI
IPC: H03H19/00
Filed: 1983-01-19
Abstract: PURPOSE:To improve remarkably the S/N of a power supply by increasing the capacitance of only required part among capacitors constituting a switched capacitor filter. CONSTITUTION:Since a noise signal N<5> of an operational amplifier OPA5 is increased further because of a positive feedback loop in which the signal is fed back via a feedback capacitor C30 of an operational amplifier OPA3, the S/N of a power supply is deteriorated. It is required to suppress a noise signal N3 generated in the operational amplifier OPA3 to improve the deterioration. Then, an integration capacitor CH3 connected between an input and an output of the operational amplifier OPA3 is increased. Further, a noise signal inputted to the operational amplifier OPA3 is suppressed at the same time. Thus, it is required to suppress a noise signal N1 generated in the operational amplifier OP1 and then to increase an integrating capacitor CH1.

Title: Delay wave detecting circuit
Inventor: AOKI SABUROU
IPC: H04L27/227
Filed: 1980-01-22
Abstract: PURPOSE:To facilitate an easy delay wave detection for the double-phase PSK modulated wave that is modulated by a low-speed data, by keeping constant via a phase varying circuit the difference of phase between the carrier wave obtained by modulating the input modulated wave by the phase detection output and the modulated wave that is delayed by a slot time. CONSTITUTION:The modulated wave supplied through the input terminal A is delayed by the delay circuit 1 by a time slot necessary for the delay wave detection system and applied to the phase comparator 3 via the phase varying circuit 1. The modulated wave supplied is also applied to the reverse modulator circuit 4 and phase detecting circuit 6, and a carrier wave is obtained by the output of the circuit 6 through the circuit 4. Then a comparison is carried out between the carrier wave and the signal passed through the circuit 2. The output of comparison is applied to the circuit 2 to keep a constant difference of phase. The output of the circuit 2 is applied to the circuit 6 via the phase device 5 for a fine adjustment of phase. Thus the phase detection output signal B is obtained.

Patent JP-H06294593-A (JP)
Title: Heat exchanger
Inventor: SEI MIKIO
IPC: F28D20/00
Filed: 1993-01-20
Abstract: PURPOSE:To hasten startup of a heat exchanger by providing a clearance between a heat accumulating body and a housing. CONSTITUTION:In a heat accumulating body 15, since an organic system accumulating material which reversibly phase-transfers between solid and liquid is supported by resin, heat is not lost. As the result, a wall for partitioning the heat accumulating body 15 from a heating medium is not required in a passage 18 of the heating medium, so that heat exchanging velocity is increased. Even if the volume of the heat accumulating body 15 is expanded as the temperature of the heat accumulating body 15 is raisesd by heat exchanging, the passage 18 of the heating medium is not blocked because there is the clearance between the heat accumulating body 15 and a housing 10, thereby heat exchanging is performed while holding the contact area of the heating medium and the heat accumulating body 15. Moreover, in the radiation of heat, the heat accumulating body 15 is contracted so as to make use of a clearance 24 as a passage of the heating medium, and the contact area of the heating medium and the heat accumulating body 15 is increased, thereby the efficiency of heat exchanging is further improved.

Abstract: PURPOSE:To improve heat radiation characteristics by a method wherein a fin-shaped cooling structure made of metal copper or silicon carbide ceramics is bonded with silver solder to a silicon carbide ceramic board supporting a semiconductor chip at their metallized surfaces. CONSTITUTION:A fin-shaped cooling structure 10 made of metal copper or silicon carbide ceramics is bonded with silver solder 6 to a silicon carbide ceramic board 2 supporting a semiconductor chip 5 at their metallized surfaces 7a and 7b. With this construction, heat generated by the chip 5 is emitted out through the board 2, the silver solder junction 9 and the structure 10. As the silver solder has a higher thermal conductivity than metal copper and silicon carbide ceramics, the heat radiation characteristics are not degraded by the silver solder junction.
