Filed: 1985-05-24
Abstract: PURPOSE:To form an optical information process of which is small in size, light in weight and also consists of a simple constitution by making the rays of light from a light source transmit through a substrate in a thickness direction, emitting it from the other face of the substrate, forming a light receiving means as a body separated from the substrate and also constituting it with a semiconductor chip. CONSTITUTION:A grating lens 13 emits the rays of light emitted from the semiconductor laser 12 of a lower part, also spread out and made to transmit through a substrate 11 and reached the lens 13, in a diagonal upper direction from the upper face of the substrate 11, and also condenses it two-dimensionally. The light receiving part 20 is used for light-receiving a reflected light from the information recording surface of an optical disk and placed at a position where the rays of light reflected in the diagonal lower direction from the position of a laser spot P can be received. The light receiving part 20 consists of four independent photodetecting elements 21-24, and these photodetecting elements 21-24 are formed on the chip 25 of a separate body from the substrate 11. The photodetecting elements 21-24 are formed, for instance, by forming four independent P-N junctions (photodiodes) on an Si chip 25.

Filed: 1986-05-14
Abstract: PURPOSE:To simplify the circuit design, to reduce number of components and to decrease the circuit scale with simple structure by incorporating a parallel data generating circuit with a synchronization detection circuit. CONSTITUTION:A synchronizing counter 15 incorporates a data bit number counter of a data detecting clock generating circuit and a data number counter. That is, before the counter 15 outputs a synchronizing signal in a serial data 1 or detects the signal, then the counter 15 acts like a counter for a signal from a selector 14. In detecting a data signal 12, the counter 15 acts like a paralle data detecting block generating ROM 23. The operation as which counter the counter 15 acts is decided by a synchronization detection signal 9. A clear signal 17 is inputted to the counter 15 before the synchronizing signal in the serial data 1 is outputted or when the signal is detected. When the data signal 12 is detected, no clear signal 17 is inputted to the counter 15 while it is regarded that the signal 12 is detected.

Title: Differential amplifier
Inventor: HASHIMOTO MASARU
IPC: H03F3/45
Filed: 1978-09-11
Abstract: PURPOSE:To reduce the output of the offset current to the output terminal and thus to eliminate occurrence of the noise at the non-signal time by changing the collector current in the differential amplification circuit to the constant current properties when the input signal is 0. CONSTITUTION:The differential amplification circuit consisting of PNP-type TrQ3 and Q4 is provided between transistor TrQ1 and Q2 in the differential amplification circuit and the power source, and the collector of TrQ6 is connected to the bases of these transistors. Then constant voltage source 2 is connected to the base of TrQ6. When the input signal is 0, the collector current of each Tr in the differential amplification circuit can ignore the offset current since the collector current of TrQ6 is constant. Thus no effect of the offset current occurs at the output, accordingly securing the function to reduce the noise output when the input signal is 0.

Title: Variable capacitance device
Inventor: SAKAI TAKAMASA
IPC: H01L29/94
Filed: 1981-07-17
Abstract: PURPOSE:To fabricate widely variable capacitance device by a method wherein n type layers  are selectively produced on the face of a p type layer on an n type wafer, and barriers for  formation of a depletion layer are formed on the reversed side of the wafer to make the n  type layer serve as depletion layer limiting regions concurrently functioning as capacitance  read-out regions. CONSTITUTION:The n type layers 11 are selectively formed on the face of the p type layer 10  on the n type silicon wafer 9. When reverse bias voltage VR is applied between a depletion  layer control electrode 13 and common eletrode 15, the depletion layer 8 is widened toward  the p type layer 10 which is of lower concentration and the n type layers 11 serve as depletion layer limiting region simultaneously so that the depletion layer concentrates at the upside of the adjoining p type layer 10. After the depletion layer reaches the n type layers 11, the depletion layer width d is rapidly increased together with value of the VR so that value of the capacitance is correspondingly reduced. Therefore, variation of the capacitance which is controlled by the reverse bias voltage VR between the electrodes 13, 15 can be read out between  the read-out electrodes 14 and common electrode 15. By such a setup, wider variation of the  capacitance can be undergone instead of making simply use of depletion layer capacitance by  application of reverse bias voltage. Independent structure of the control region and the read-out region allows the device to be free from adverse effects by input signals.
