Title: Vapor-phase epitaxial growth
Inventor: KOBAYASHI KENICHI
IPC: H01L21/205
Filed: 1985-10-11
Abstract: PURPOSE:To epitaxially grow a compound semiconductor with slight composition disorder in the vapor phase, by passing an organoaluminum through a mixture solution of trimethylaluminum and triethylaluminum at a specific temperature and transporting the organoaluminum onto a substrate crystal. CONSTITUTION:A mixture solution of trimethylaluminum and triethylaluminum is set at a temperature below the freezing temperature of the trimethylaluminum and a carrier gas, e.g. H2, N2 or an inert gas, is passed through the mixture solution to lead the carrier gas containing the organoaluminum onto a substrate crystal for epitaxial grow in the vapor phase.

Title: Orthogonal conversion coding device
Inventor: TANOI HISAYUKI
IPC: H04N19/60
Filed: 1988-09-12
Abstract: PURPOSE:To improve transmission efficiency by multiplying a coefficient less than the unity to a prediction signal using correlation of time base signals so as to apply prediction coding of leakage integration type. CONSTITUTION:A prediction coefficient circuit 10 applies prediction coding of leakage integration type by multiplying a predetermined value less than the unity with an inter-frame prediction signal (g) using correlation of time base signals to output a prediction signal (h). If the calculation accuracy of an orthogonal converter 3 and an orthogonal inverse converter 28 differs, the difference from the arithmetic accuracy in a decoder side, that is, the rate of accumulation of the arithmetic error due to mismatching as the elapse of time is suppressed. As a result, the time reaching a threshold level in which a periodic refresh has to be implemented is extended. Thus, the transmission efficiency is improved.
Patent JP-H0389651-A (JP)
Title: Digital phase detector
Inventor: ITO REI
IPC: H04L27/22
Filed: 1989-08-31
Abstract: PURPOSE:To eliminate a need of a complicated phase reference signal generating circuit and an expensive digital complex multiplier by setting the sampling clock of A/D conversion to 4-fold phase reference frequency. CONSTITUTION:The sampling clock frequency of A/D conversion is set to 4-fold phase reference signal frequency. An output signal 4 to which an input signal 2 is digitized by an A/D converter 1 is distributed to two systems, and one is sent to a changeover switch 7 as it is, and the other is sent to it through a code inverting circuit 5, and they are selected by the switch 7. By this operation, the same effect that the output signal 4 is multiplied by +1 or -1 is obtained. The output signal is sampled by a data latch 8 in accordance with sampling timings Iref and Qref thereafter. Thus, this device does not require the phase reference signal generating circuit and the digital multiplexer and requires only the sampling circuit and the code inverting circuit.

Title: Zero cross amplifier
Inventor: ABE YUUHEI
IPC: H03K6/00
Filed: 1983-12-02
Abstract: PURPOSE:To simplify the circuit constitution and to improve the reliability by connecting diode limiters having a common input to a pair of input terminals of a comparator. CONSTITUTION:Diodes 6 and 7 having a common input (a) are connected with opposite polarities to each to a pair of inputs of a comparator 1 consisting of a differential amplifier.

Title: Program parts synthesizing device/method
Inventor: SANADA NORIO
IPC: G06F9/06
Filed: 1992-08-26
Abstract: PURPOSE:To inspect the parts which are used in a synthesization mode and then to automatically change the parts by defining the sending destination of the instruction included in a program as a set name to which a subject belongs. CONSTITUTION:A program parts selecting part 105 sorts the program parts whose program specifications and the instruction sending destinations are defined as the set names to which the sending destinations belong for each function. Then the necessary parts are read out of a program parts storing part 102, and the sending destinations of all instructions which are used in respective parts are inspected to decide whether all sending destinations of the extracted instructions are read out or not. If so, the sending destination names of the program parts are converted into the corresponding parts names for generation of a correct program. Since it is not required to uniquely describe the sending destination of the instruction into each program part the redescription of the code of the program parts is no longer required despite the change of the parts. Thus the parts can be synthesized.
