Patent JP-S5928368-A (JP)
Title: Semiconductor capacitor
Inventor: YAMAGUCHI TAKASHI
IPC: H01L29/93
Filed: 1982-08-09
Abstract: PURPOSE:To contrive to increase the value of capacity by a method wherein a row of deep grooves or an unevenness is provided on the surface of an N (or P)- type semiconductor substrate, a P (or N)-layer is superposed, and then the P-N junction is determined as a capacitor. CONSTITUTION:The row of deep grooves 11 is formed by selectively etching the surface of the N type Si layer 10, the P-epitaxial layer 12 is superposed, windows are opened through the SiO2 film 13 of the flatted surface, and Al electrodes 14 and 15 are laid. As the angle of inclination theta of a groove is more increased, and widths (a) and (b) of the flat part are more decreased, the surface area more increases, and accordingly the P-N junction capacity more increases. When rows of grooves are provided lengthwise and crosswise, the rate of increase of the surface area becomes the second power of the case of one direction. Or, when an N<+> diffused layer 17 is provided on the surface of the deep etched groove 11, an Al electrode 19 is provided via a thermal oxide film 18, an N<+> layer 20 and an electrode 21 are provided outside the groove row region, the value of capacity can be also increased. This constitution enables to increase the value of capacity with the same area.

Title: Vibrationproof control device for refrigerating cycle
Inventor: IKETANI JITSUO
IPC: F25B1/00
Filed: 1985-06-26
Abstract: PURPOSE:To prevent resonance from being produced within a refrigerating cycle by providing a control device which detects, through a sensor, the vibration of a piping connected to a compressor, and reduces such vibration through changing the output frequency of an inverter in response to the amplitude of the vibration detected. CONSTITUTION:During the heating or cooling operation, a compressor 1 is controlled by an inverter 2 to make its rotational speed in response to the load applied, and the vibration of a suction pipe 4 is detected by an optical sensor 13 during said operation. In addition, when the amplitude of the detected vibration is larger than the permissible value, and the suction pipe 4 is resonating with the vibration of the compressor 1, a control device 15 detects the evaporation temperature, through a sensor 17 firstly. And then, if the detected temperature is 10 deg.C, the control device 15 judges that the suction pipe 4 is in the state of ice coating, and control the opening of an expansion valve 7 so that the ice coating is removed. While, if the temperature is not lower than 10 deg.C, the control device 15 increases the frequency to a level one step higher in ranks. And then, if the resonance is caused to cease, the control device 15 permits the compressor 1 to be in operation as before. While, if the resonance remains still at a high level, the control device 15 directs the compressor 1 to discontinue its operation. Thereby, an abnormal resonance can be prevented, and the reliability of the refrigerating cycle can also be improved.

Title: Piezoelectric element, piezoelectric vibrator using the element sounding body, piezoelectric actuator, ultrasonic contact and piezoelectric transformer
Inventor: OMOTE ATSUSHI
IPC: H02N2/00
Filed: 1998-05-20
Abstract: PROBLEM TO BE SOLVED: To make it possible to obtain the favorable piezoelectric characteristics of a piezoelectric element in a wide temperature range by a method wherein in a piezoelectric material provided with more than two electrodes, the two electrodes subjected to polarization treatment are short-circuited using a resistor. SOLUTION: In the case where a piezoelectric element, which consists of a piezoelectric material 4 and is a ferroelectric perovskite-type oxide element 1, is used in a film thickness of 100 μm, a voltage of 100 to 400 V is applied to the element to polarize the element, but when the temperature of this element is abruptly changed from -40 deg.C to 100 deg.C, a high change is generated in the element and a voltage of several 100 V is easily applied to the element itself. At this time, a lot of time is required for discharge, a voltage equal with that at the time of the polarization of the element is applied to the element for a long time and a depolarization of the element is simply caused through. Owing to this, electrodes 2 of the element is short-circuited using a resistor.  Thereby, the charge generated by heat is always discharged and as the application of the voltage to the element, which is attributed the piezoelectric characteristics of the element to the main cause, is not caused at all, the characteristics of the element are also not deteriorated.

Title: Method for producing base material for additive for casting of steel
Inventor: MARUYAMANO TOSHIKAZU
IPC: B22D1/00
Filed: 1982-08-10
Abstract: PURPOSE:To provide an additive having less fluctuating and uniform components by limiting the mixing ratio of the coke to be mixed with the raw material of the additive for casting of steel and the blast rate of a water cooled type cupola for melting the raw material. CONSTITUTION:Bed coke 2 is charged into a water cooled type cupola 1, and coke is charged at 16-28% coke ratio to a raw material 3 for an additive for casting and after the coke is ignited, the raw material is melted by operating the cupola at 90-110Nm<3>/minm<2> flow rate of the blast through tuyeres 5. Then the melt is coated as a lining layer 8 on a water cooling jacket part 4 to protect the jacket 4 and to prevent the entry of an iron-component. The melt is charged through a tapping port 6 into a water tank and is made into a base material for the additive after water granulation and drying. The reason for limiting the coke ratio and the blast rate lies in that if these are out of said range the operation of the cupola is difficult and further the variance in the melt component of the raw material increases. In addition, there is the tendency toward the decrease in the yield of fluorides and alkali metals.
