Title: Piezoelectric transformer
Inventor: SATO MASUJI
IPC: H01L41/107
Filed: 1991-04-24
Abstract: PURPOSE:To prevent deterioration of characteristics of a piezoelectric transformer by finishing a surface of a piezoelectric substrate in a roughly polished state, and suppressing flowout of solder melted to a drawer terminal pad to input/output electrodes. CONSTITUTION:Since a surface of a piezoelectric substrate 1 is formed in a rough state, input/output electrodes 2, 3, drawer terminal pads 20, 30 and connecting wirings 22, 33 are all formed on the surfaces in rough states. Accordingly, when solder 4 is fusion-bonding to the pads 20, 30, a resistance to flow of the solder 4 is increased, flowout 4' of the solder 4 is stopped substantially in a range of the wirings 22, 33, and not fed to a range of the electrodes 2, 3. Thus, characteristics of a piezoelectric transformer can be maintained excellent.

Title: Apparatus and method for controlling brushless motor, and self-priming pump
Inventor: SUEMATSU SHINJI
IPC: H02P6/21
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To avoid a stepped out brushless motor caused by counter-electromotive force by providing a changeover control part which changes compulsory synchronous control over to feedback synchronous control, when the phase difference between a compulsory synchronous control signal and a feedback synchronous control signal becomes a specified value or less. SOLUTION: A feedback synchronous control signal generating part 130 generates feedback synchronous control signals VU1, VV1, VW1 for performing changeover of driving currents which are caused to flow in stator windings by a driving circuit, on the basis of a zero-cross point. Next, a changeover control part 135 changes control of a brushless motor from compulsory synchronous control over to feedback synchronous control, when the phase difference between compulsory synchronous control signals VU2, VV2 VW2 and the feedback synchronous control signals VU1, VV1, VW1 becomes a specified value or less. A driving voltage changeover part 136 starts the brushless motor by a driving voltage lower than a rated driving voltage. After the control is changed over to feedback synchronous control, the driving voltage is changed over to the rated driving voltage.  Consequently, increase of the driving current and step out of the brushless motor which used to occur on the occasion of changeover are prevented.

Title: Semiconductor memory
Inventor: ATSUMI SHIGERU
IPC: G11C16/28
Filed: 1983-05-26
Abstract: PURPOSE:To increase the margin to the fluctuation of a process parameter by increasing the difference between the high and low levels of the potential at an input node of a sense amplifier on a bit line which is decided by the memory contents of a memory cell and slowing the change of the potential of the input node to the potential change of the bit line. CONSTITUTION:A p channel load formed by connecting the gate and the drain of a p channel enhancement type transistor TR40 to each other is used as a load circuit of a bit line of a CMOS EPROM. The high level of the potential VB of a node B rises up to VCC-VTHP (threshold voltage of TR40) in a read mode when a memory cell is under a non-write mode since the p channel load receives no effect of a back gate bias effect. As a result, the difference between the high and low levels of the potential VB is increased. The TR40 works in a saturated area and its conductance is proportional to (VCC-VTHP-Va)<2>. Therefore the change of the VB of the node B is comparatively slow compared with the change of the potential VD of a node D.

Title: Josephson exclusive or circuit
Inventor: OOBORI TATSUYA
IPC: H03K19/195
Filed: 1982-05-31
Abstract: PURPOSE:To attain an exclusive OR circuit having a high margin, by designing so that cancellation of a current for obtaining the exclusive OR operation is made independent of the dynamic behavior of Josephson elements. CONSTITUTION:A branch line comprising Josephson elements J5, J6 and resistors R6, R7 in order is connected in parallel with a terminal D connected to a bias supply line, and input signal lines are connected to the connecting point between the Josephson element and the resistor, respectively. When an input is given to both input terminals F, G, the input signal current is shunted with the resistors R6, R7 and the current flowing to the Josephson elements J5, J6 is almost zero. In this case, in flowing a bias current IT from the terminal D, the current flows to ground without switching the Josephson elements, and no output is produced at a terminal E. When an input is given to the terminal F only, the Josephson elements are switched and an output is produced at the terminal E.

Title: Separation control system for nuclear reactor containment and nuclear reactor pressure vessel
Inventor: FUJII MASAHIKO
IPC: G21D3/06
Filed: 1989-04-14
Abstract: PURPOSE:To reduce a burden on an operator by setting water level set points for separation of separation valves in lines other than a main vapor line, which are separated by the reduction of the nuclear reactor water level, to points lower than the lowest water level for trip of the turbine side and higher than set points for separation due to the reduction of the water level. CONSTITUTION:The principal object is to set the nuclear reactor water level to a set point L-2 or lower in all of a separation control system for nuclear reactor containment and nuclear reactor pressure vessel (PCIS), and the nuclear reactor water level is kept in the range from a water level set point L-7 to a water level set point L-4 during normal operation. If the water level falls to the set point L-4 because of some abnormality of a power plant, an alarm for reduction of the nuclear reactor water level is generated. If it is reduced to a lower set point L-3, nuclear reactor scram is operated, and an emergency gas treatment device to suppress emission of radioactivity is started. If the water level is reduced to a set point L-2, a part of a cooling system for nuclear reactor separation system and an emergency core cooling system is started. Thus, unnecessary separating operation is prevented.

Title: Device for measuring distance and speed
Inventor: MATSUZAKI HIROSHI
IPC: G01D21/02
Filed: 1993-04-20
Abstract: PURPOSE:To reduce error even under poor S/N condition and provide measurability with high accuracy by calculating the distance and speed from the reception signal which is decided as effective with a trigger signal, and thereupon determining their mean values. CONSTITUTION:Light emitting elements 1-a thru 1-f emit measuring beams of light having undergone an intensity modulation made by a light emitting element driving circuit 2, and when any object intercepts the measuring beam(s), spot images generated at this time are image formed on position sensitive detectors 5-a, 5-b by receiving optical systems 4-a, 4-b. The corresponding signal in the position is taken in by a sensed light processing circuit 6, and sampling is made at appropriate time intervals, and the result is subjected to A/D conversion. Therein the processing circuit 6 judges that the object is going to touch any of the measuring beams, when the intensity of the sensing signal in monitoring has exceeded the threshold, and calculates the distance with the A/D converted value. Any signal which does not attain the threshold is treated as ineffective. This allows avoiding measurement involving a large error caused by signals bearing a poor S/N. Statistic treatment is made for region by region to be measured with each beam so that the mean values of the distance and speed are obtained, and a highly accurate measurement is made practicable.

Filed: 1988-04-18
Abstract: PURPOSE:To prevent an abnormal image from being formed by detecting the rotating speed of a photosensitive drum by utilizing laser Doppler effect, and controlling the driving current of a motor if the rotation becomes irregular and putting it in stationary rotation. CONSTITUTION:A laser beam L which has an angle phi of intersection is projected on one point on a photosensitive drum 4 in two directions, and a photodetector 21 detects the angle DELTAtheta between their scattered light beams at the reflection point. The rotating speed V of the photosensitive drum 4 is detected from the Doppler frequency fd=2V/lambdasinphi/2cosDELTAtheta (where phi is the angle of intersection of the laser beam L and lambda is the wavelength of the laser beam) which is obtained at this time and the control current value of the motor which is opposite in phase with the detected current value corresponding to the current irregular rotating speed, so that both current values cancel each other. Consequently, an irregularity of rotation is precluded and an image of excellent quality is obtained.
