Patent JP-S57142012-A (JP)
Title: Transistor circuit
Inventor: OSHIO UMEO
IPC: H03F3/42
Filed: 1981-02-27
Abstract: PURPOSE: To achieve a large amplitude output, by giving an input signal at an inverse phase relation to two series-connected transistors (TR) provided between power supply terminals and keeping the base potential at high potential side to an intermediate level of the power supply voltage.  
     CONSTITUTION: When an input signal is given to a terminal IN, the base potential of a TRQ 1  for buffer follows so that it is at higher potential than the collector potential of an output TRQ by VBE. Thus, when the collector potential of the TRQ is sufficiently lowered, since the collector potential of the TRQ 1  is sufficiently lowered with the base potential, an output voltage amplitude from a terminal OUT exceeds a voltage given to the base of the TRQ 1  to be sufficiently greater. As a result, an output voltage exceeding the rating of the output TRQ can be achieved.

Title: Avalanche photodiode
Inventor: KUWAZUKA HARUHIKO
IPC: H01L31/107
Filed: 1990-02-07
Abstract: PURPOSE:To control the width of a multiplication layer with good accuracy and to increase a G-B product by a method wherein a semiconductor layer which forms a Schottky barrier against a metal electrode is formed between the metal electrode and an InP layer. CONSTITUTION:A metal layer 12 is formed against an n<-> InP multiplication layer 3 via an AlInAs layer 11. The metal layer 12 is constituted in such a way that a Pt layer and an Au layer are laminated on a Ti layer which forms a Schottky barrier against the AlInAs layer. The AlInAs layer is formed because it is difficult to form a Schottky junction against the n<-> InP layer as a carrier amplification region. GaAs or the like in addition to AlInAs can be used as the Schottky formation layer. Thereby, it is possible to control the width of the multiplication layer with good accuracy.

IPC: G06F1/12
Filed: 1997-02-13
Abstract: PROBLEM TO BE SOLVED: To supply a clock signal stable in a digital communication network. SOLUTION: A scaling-type phase detecting equipment PD generates a phase shift term Φdev being equal to phase difference between a local oscillator signal 42 where scaling is executed in a frequency by the ratio of a nominal reference frequency frnom and a nominal oscillator frequency fxnom and a reference signal R. A signal processor 14 processes it so as to generate a synthesizer correcting term ds, corrects the nominal synthesis rate Rnom (the ratio of a nominal clock frequency fcnom and a nominal oscillator frequency fxnom ) of a signal synthesizer 34 based on the synthesizer correcting term by an operand correcting element DR and obtains the clock signal from the local oscillator signal 42. For example, ds consists of the frequency correcting term df which is obtained by calculating the change speed of Φdev .  DR is calculated by an expression, DR =(df×fcnom )/(frnom ×fxnom ) and added to Rnom at every cycle of the local oscillator.
