Title: Method of screening resin-sealed semiconductor device and resin-sealed semiconductor device used therein
Inventor: OTANI KOZO
IPC: G01R31/26
Filed: 1985-06-29
Abstract: PURPOSE:To effectively apply a voltage only to a portion of a device which must be screened so as to eliminate any adverse effect to the other portions, by applying the screening voltage to a tie bar only after finishing the assembly. CONSTITUTION:A screening voltage is applied between an outer lead 22 and a tie bar extension 28 both projected from a sealing resin 21. The voltage is thereby applied, from the tie bar extension 28 through the tie bar 23, a bed 25, a conductive mounting material 26 and the substrate of a pellet 27, to the capacitance within the pellet, so that only the capacitance is screened. Since no voltage is applied to an MOS transistor within the pellet, the MOS transistor can be prevented from being broken by the screening voltage. After finishing the screening, said tie bar extension 28 is cut off in the vicinity of the surface of the sealing resin 21.

IPC: H03H11/36
Filed: 1982-08-18
Abstract: PURPOSE:To switch automatically a signal level for mixing, by providing an amplifier inputting at least one signal and having almost zero output impedance and a switching element superimposing the output of the amplifier on other signals via a resistor. CONSTITUTION:An output of a tone signal generator 1 and a microphone 2 is mixed by turning on/off a switch 3. In transmitting a tone signal only, when the switch 3 is turned off, an analog switch 11 is brought into the off-state, the tone signal of the generator 1 is applied to an amplifier 13 via a variable resistor RV3, a capacitor C3 and a resistor R3 and transmitted to an output terminal 10. In superimposing the tone signal and a sound signal, the switch 3 is turned on, and the switch 11 is turned on. An output impedance of the amplifier 12 is set almost zero and the level of the tone signal applied to the amplifier 13 is decreased in comparison with the level when the switch 11 is turned off. Further, the sound signal of the microphone 2 is outputted via an amplifier 12, the switch 11, a resistor R4 and the amplifier 13.

Abstract: PURPOSE:To execute an exact selection by means of a simple operation, by detecting the position of a designation means by the photoelectric conversion means which scans as original image and converts it to an electric signal, so that the reproducing image can be selected. CONSTITUTION:In case of scanning an origianl, the change-over switch 309 is changed to the side of (b), and an image signal which has been read by the photoelectric conversion element is input to the gate circuit 310 from the photoelectic converting circuit 306. The signals showing the effective width in the main scanning direction, which have been stored in advance in the shift register 308 are output in order to the gate circuit 310, and control the picture signal. The gate circuit 310, for instance, outputs an image signal when the output of the shift register 308 is ''1'', and does not output the image signal when the output is ''0''. Also, the output from the shift register 308 is fed back, is stored again in the shift register 308, is repeated whenever one scanning line is read out, and when scanning of one line has been finished, it is shifted to the next line.

Filed: 1991-05-20
Abstract: PURPOSE:To attain the transmission/reception of composite signals by the same radio carrier by modulating the frequency of a telephone signal by means of one time slot in a radio channel allocated between a mobile radio set and a radio base station and then modulating the amplitude of the Modulated telephone signal by a facsimile signal to transmit/receive the amplitude-modulated signal. CONSTITUTION:When many mobile radio sets 100-1 to 100-n exist in the service area of the radio base station 30, one radio channel is time-divided into plural time slot sequences in order to attain communication between the optional number of radio sets and the base station. Then one of the sequences is selected to execute communication. When a certain radio set is being communicated with the base station 30 by means of a composite signal, a radio set newly requiring communication by means of a composite signal is allowed to communicate with the base station 30 by applying one of unused sequences to the using radio channel. Thus the mutual interference of many communication cases can be prevented and bad influence to self communication can be suppressed.

Title: Ultrasonic wave motor
Inventor: SASHITA TOSHIO
IPC: H02N2/00
Filed: 1987-06-08
Abstract: PURPOSE:To obtain the ultrasonic wave motor of low speed and high torque which can be worked by low voltage and at high efficiency, by composing an oscillating unit having the uniform elasticity of high elasticity on the contact section side with a mover against the direction confronted with the mover, and of low elasticity on the bonded section with a piezoelectric unit. CONSTITUTION:So far as the oscillating unit 7 of an ultrasonic wave motor is concerned, hollow sections 6a are arranged on the bonded section side 6 with a piezoelectric unit 2. Accordingly, if the elastic coefficient of material is uniform the elasticity of the contact section side 5 with a mover is made greater than that of the bonded section side 6 with the piezoelectric unit 2, in appearance. As a result, comparing this case with the case of the whole oscillating unit 7 having uniform elasticity, the same vertical amplitude w can be generated on the contact surface 5a with the mover by less voltage, and a device can be worked with low tension, and efficiency can be enhanced.
