Title: Apparatus for charging battery
Inventor: SHINOHARA SHIGERU
IPC: H01M10/44
Filed: 1990-11-22
Abstract: PURPOSE:To charge a secondary battery in a short time, switching over charging current in an optimum way even when the variation of the charging characteristic of the secondary battery, which is caused by the battery itself and its ambient temperature, is present, by sensing that the gradient of the differentiated value of the output change of a battery voltage sensing means is changed from a positive to negative value, and by switching over the charging current. CONSTITUTION:When a charging is started, an analog switch 68 is switched off, and the amplification factor of the first stage is decreased, and further, the charging by a large current is started. When it is sensed that the gradient of the differentiated value of the output change of a means 40 for sensing a battery voltage is changed from a positive to negative value, the analog switch 68 is switched on by the signal at an output port 56 of a microcomputer 50. Then, the amplification factor of the first stage is increased, and the charging by a small current is started. Thereby, even when the variation of the charging characteristic of a secondary battery, which is caused by the battery itself and its ambient temperature, is present, the secondary battery can be charged adequately.

Title: Electric field effect transistor logic circuit
Inventor: TANOI SATOSHI
IPC: H03K19/094
Filed: 1987-12-18
Abstract: PURPOSE:To cause a logical amplitude to be wide, to obtain a high speed and to enlarge a noise margin without especially complexing a manufacture procedure by discharging a gate charge in the normally-on type FET (EFET) for driver of a DCFL like a direct current with the EFET of a coupling circuit. CONSTITUTION:When an input signal Vin to be supplied to an input terminal 21 is a potential Vih of an H, a charging current Ih is flown from the input terminal 21 to a node A and a potential Va of the node A rises up. As a result, as long as the H potential Vih of the input signal Vin is Vih<2Vf, neither the parasitic diodes a diode 31 nor an EFET23 is turned on and clamp effect is not generated. Accordingly, the logical amplitude can be made wide and the noise margin can be enlarged. On the other hand, when the input signal Vin is changed from the H potential Vih to an L potential Vil, a discharging current Il is flown from the node A to the input terminal 21. Accordingly, when a potential Va is slightly higher than the input signal Vin, an EFET32 is turned on and the discharging current Il like the direct current is made to flow.

Title: Bias circuit
Inventor: YOSHIDA NAOMI
IPC: H03F1/30
Filed: 1988-12-21
Abstract: PURPOSE:To attain the expansion of the output voltage range and low power consumption of a circuit using a bias voltage by generating the bias voltage corresponding to the fluctuation of the VTH of an insulated gate type field affect transistor(MOS transistor). CONSTITUTION:A source voltage is divided into three by P-channel MOS transistors 1-3, and a constant voltage is supplied to the gate of a P-channel MOS transistor 4. Assuming a voltage between the gate and the source of the transistor as VGS and a threshold voltage as VTH, the constant voltage is set so that a value (VGS-VTH) can be set sufficiently larger than the fluctuation of the VTH, and a cur rent on a bias circuit 10 can be kept almost constant. And the VGS corresponding to the current is generated at an N-channel MDS transistor 5, and the voltage goes to the bias voltage, and when the VTH fluctuates, the VGS i.e. the bias voltage changes corresponding to the above fluctuation. In such a way, since a low voltage value as the bias voltage can be set, it is possible to attain the expansion of the range of the output voltage and the low power consumption in the circuit using the voltage value.

Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To excit an ultrasonic vibrator without fail by a method wherein a frequency is swept from a frequency which is higher than the resonance frequency of the ultrasonic vibrator by a certain frequency. SOLUTION: A sweep voltage generator 6 operates so as to reduce an initial set voltage with a predetermined reduction rate. An adder 5 adds the output of the sweep voltage generator 6 to the output of an offset voltage generator 7. A VCO 1 outputs a high frequency voltage which is a driving frequency signal for an ultrasonic vibrator 30 in accordance with the output of the adder 5. A phase shifter 2 shifts the phase of the frequency signal outputted by the VCO 1 forward or backward by 90 degrees. First and second amplifiers 3 and 4 amplify the high frequency voltages which have a phase difference of 90 degrees between each other and apply the amplified voltages to layer-built piezoelectric devices attached to the ultrasonic vibrator 30. With this constitution, the ultrasonic vibration of the ultrasonic vibrator 30 can be excited without fail to drive an ultrasonic motor 40.

Title: Manufacture of molding with high density skin layer
Inventor: YOKOYAMA MASAAKI
IPC: B29K105/04
Filed: 1997-11-06
Abstract: PROBLEM TO BE SOLVED: To provide a qualitatively uniform and hard skin layer which is almost free from shrinkage by filling a mold with foamable resin particles under compression so that the particles show a specific compressibility, then heating the particles to a temperature higher than a melt point to form the skin layer on the surface of a molding which comes into contact with the mold, and removing an air from between the particles when the area pressure of the particles is within a specific range to thermally fuse the textures of the resin mutually. SOLUTION: Foaming particles contained in a compression charging tank 4 are charged into the cavity 3 of a mold which is preheated and hermetically sealed within the range of 3-70% of the compressibility C shown by formula C=(1-ρ1/((ρ2×2t2+ρ3×t3)/(t1))×100 (wherein, C is compressibility %; ρ1 is the density kg/m<3> of foamable resin particles before charging; ρ2 is the density kg/m<3> of a skin layer part; ρ3 is the density kg/m<3> of a part other than the skin layer part; t1 is the wall thickness mm of a molding; t2 is the thickness mm of the skin layer part; and t3 is the thickness mm of part other than the skin layer). The halves of the mold are heated at a temperature level above the melts point of the foamable particles.  When the area pressure of the foamable particles in the cavity 3 is down to 0.01-1.5 kg/cm<2> G, the foamable particles are mutually fused together after exhausting the air. Thus it is possible to form a qualitatively uniform and high density hard skin layer over the entire face of a molding and consequently, obtain the molding almost free from shrinkage.
