Title: Controller of ac electric vehicle
Inventor: SHIODA TAKESHI
IPC: B60L9/12
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To reduce high-frequency currents flowing to a motor, and reduce noise, by connecting an AC capacitor in series to the system in the low speed range of an AC electric vehicle thereby lowering DC voltage, and short-circuiting the AC capacitor in high speed range thereby maintaining high DC voltage. SOLUTION: The high frequency voltage in a fixed speed range including the start time of an AC electric vehicle is reduced by setting the DC voltage VD is set low when an AC electric vehicle is at low speed, and increasing the DC voltage VD when the speed goes up. An AC capacitor 15 is connected in series between an AC power source 1 and a reactor 11, and a switch 16 is connected in parallel with the AC capacitor 15. The AC capacitor 15 is connected in series to the system by turning off the switch 16 when the AC electric vehicle is at low speed. Hereby, even if the DC voltage VD is low, the ascent and descent of the DC voltage VD can be controlled. Therefore, the high frequency currents flowing to the motor and the noise can be reduced.

Title: Photomask
Inventor: IDENO SHINICHI
IPC: G03F1/52
Filed: 1991-04-08
Abstract: PURPOSE:To improve pattern transfer accuracy and durability to laser light by laminating a laser light reflecting film on a glass substrate so that adjacent dielectric layers differ in refractive index. CONSTITUTION:The glass substrate 1 which transmits the wavelength of the object laser light is used and, for example, lead glass, etc., is used. On the glass substrate 1, the laser light reflecting film 7 is laminated so that the dielectric layers 7a and 7b which differ in refractive index adjoin to each other. Those dielectric layers 7a and 7b transmit the wavelength of the objective laser light and there is, for example, fluoride. When the refractive indexes n1 and n2 of the dielectric layers 7a and 7b are so determined that n1>n2, the reflected light at the border where the laser light is incident on the dielectric layer 7b from the dielectric layer 7a is in phase with the incident light and when n1<n2, the light is reflected, thereby increasing the reflection effect. Thus, the laser light is reflected and cut off without being absorbed, so pattern deterioration is lessened.

Title: Heat exchanger
Inventor: ANDO TOMOAKI
IPC: F25B39/02
Filed: 1989-04-24
Abstract: PURPOSE:To cause homogenous gas-liquid two phase flow to be split flow uniformly into each of thermal conducting pipes by a method wherein a header is provided with means for separately flowing either liquid or gas-liquid two phase flow having a high rate of liquid and either gas or gas-liquid two phase flow having rate of gas. CONSTITUTION:In a gas-liquid separator 6, a refrigerant 2 is divided into either liquid or two-phase gas-liquid flow 2A having a high rate of liquid and either gas or two- phase gas-liquid flow 2B having a high rate of gas. Fluid 2A passes through a piping 7A and flows upwardly to a header 4. Similarly, fluid 2B passes through a piping 7B and flows downwardly to the header 4. In the header 4, the fluid 2A has a high mean specific weight and the fluid 2B has a low mean specific weight, so that the fluids 2A and 2B are mixed well to form two-phase flow of gas and liquid having a uniform flow in which a degree of dryness and a voids are relatively uniform in their values. In addition, a more homogenous two-phase flow of gas and liquid can be realized due to a phenomenon of capillary tube through a metallic mesh 8. This two-phase flow of liquid and gas is distributed into each of the thermal conducting pipes 1 and performs a heat exchanging operation with the ambient air while being flowed and then the flow is evaporated.

Title: Audio signal transmitting receiving system
Inventor: AMADA NOBUTAKA
IPC: H04L27/34
Filed: 1987-04-30
Abstract: PURPOSE:To transmit and receive a voice PCM broadcasting while coexisting with a current FM broadcasting system by making the modulating system of a digital modulator into the multi-value orthogonal amplitude modulating system of hexadecimal values or above and setting the transmitting frequency of a multi-value orthogonal amplitude modulating signal to the arbitrary frequency in the FM broadcasting band of a VHF band. CONSTITUTION:As the modulating system of a voice PCM signal, a waveform equalizing circuit is further inserted to a receiving side with a multi-value orthogonal amplitude modulating QAM system of hexadecimal values or above. The QAM system is the modulating system to change both the amplitude and phase of a carrier and the modulating signal is obtained by synthesizing two orthogonal ASK signals. The hexadecimal value QAM system makes the ASK signal into four values and the band width of the modulating signal is made into a narrow band for quarter the transmission rate. Consequently, the voice PCM signal of 1Mbps, when the hexadecimal value QAM system is used, can be transmitted at the same 250KHz as the band width of the current FM stereo broadcasting. Thus, to the voice PCM signal of 2Mbps, transmission can be executed in the same way at a 250KHz band width by using a 256(2<8>) value QAM system to advance further the multi-value.

Title: Semiconductor integrated circuit
Inventor: HARA HIROYUKI
IPC: H01L21/8249
Filed: 1990-04-20
Abstract: PURPOSE:To increase the operation speed of a semiconductor integrated circuit by connecting the back gate of an N type MOS transistor TR, which supplies a current to the base of a bipolar TR, to its own source. CONSTITUTION:The back gate of an N type MOS TR 12 which drives the base of an NPN bipolar TR 14 is connected to the source of this TR 12. Though TRs 11 and 13 are used for rise current supply, the TR 13 improves the current driven capability of the TR 11. Though TRs 12 and 14 are used for fall current supply (pulled in from a terminal 18), the TR 14 improves the current driven capability of the TR 12. Thus, the source and the back gate of the TR 12 are set to the same potential to eliminate the back gate effect of the TR 12, and the reduction of the speed for output fall is suppressed to increase the operation speed of the semiconductor integrated circuit.
