Title: Error check system
Inventor: HASEGAWA HITOSHI
IPC: H04L1/00
Filed: 1993-06-08
Abstract: PURPOSE:To attain error check with higher capability efficiently by comparing an error check code generated based on transmission data with an error check code generated based on received data so as to check the number of errors. CONSTITUTION:A clock signal generating section 1 of a generating section 10 applies 1/2 frequency division to a master clock signal synchronously with a main signal of plural lines received from a sender side to generate 1st and 2nd clock signals opposite in the phase to each other. A data latch section 2 latches main signal data of a phase (odd number order) corresponding to an 8-th line synchronously with the first clock signal. An arithmetic operation section 3 makes generating arithmetic operation of an error check code for latch data in parallel 8-bit of an odd number order in the latch section 2 and main signal data in parallel 8-bit of a phase (even number order) corresponding to an 8-th line synchronously with a 2nd clock signal. Furthermore, a generating section 10' of a check section 20 generates an error check code based on received data and an extract section 11 extracts the code. A latch section 12 compares the extracted and generated error check signals and a count section 13 detects an error number of the latch section 12.

Title: Input and output processor
Inventor: TANAKA YASUHARU
IPC: G06F13/42
Filed: 1983-07-27
Abstract: PURPOSE:To improve input/output (I/O) processing performance when an input/ output interruption request is accepted from a peripheral equipment which has a different speed by varying a sequence after the acceptance of the I/O interruption request according to respective channel ports. CONSTITUTION:An I/O 1 consists of an I/O control part 2 and three I/O channel ports 3. Signals indicating the channel number of the channel ports 3, received by the accepting circuit 20 of a control part 2, varies in value according to the channel number. Consequently, when a port having a short control sequence is accepted after a port having a control sequence extending between two clocks is accepted by interruption, sequence operation is delayed by two clocks. Thus, and overlap of control sequences is avoided. Namely, the I/O processing performance when an interruption request from a peripheral equipment having a different speed is accepted is improved.

Title: Receiver
Inventor: IENAKA MASANORI
IPC: H03G1/00
Filed: 1980-10-06
Abstract: PURPOSE:To improve senitivity and high input signal characteristics by switching the impedance of a transistor, constituting an RF amplification stage, by a switching means controlled on the basis of the difference between a prescribed constant current and an AGC signal. CONSTITUTION:During the reception of a low input signal, an AGC current from a transistor TRQ10 is less than a constant current generated by a TRQ3, so a bias current corresponding to their difference flows through a TRQ2'. Therefore, the TRQ2' turns on to perform amplifying operation with the emitter grounded via a capacitor C105, improving the sensitivity. During the reception of an intermediate signal or greater, the AGC current becomes greater than the constant current generated by the TRQ3, so the TRQ2' turns off to give effect to amplifying operation by an amplifying TRQ1 having a resistance R1 at its emitter. During the reception of a high input signal, the collector potential of a TRQ10 rises as the AGC current increases, and the conductivity of a differential TRQ5 increases, thereby performing gain limiting operation by the differential TRs Q4 and Q5.

Abstract: PURPOSE:To provide sure transportation of thin and long magnetic parts by arranging a magnet assembly, which is capable of reciprocating along a saw- teeth shaped guide path, in such a way that the surfaces of assembly bearing different polarities are situated apart in the width direction of the guide path, and thereby detaining each magnetic object with the teeth surely. CONSTITUTION:A moving part 56 of a magnet assembly is supported by rails 62, 68 and a bearing 66 in such a way as capable of reciprocating and includes a plurality of permanent magnets 72 arranged at a certain spacing in longitudinal direction and yokes 70 stretching in the width direction on a coupling 58 moving during reciprocation while deformed elastically. When the moving part 56 makes reciprocation, the magnetically acting range of a magnet 52 consisting of a plurality of permanent magnets 72 and yokes 70 will pass at least one of the steps 38 of a transport guide path to transport magnetic objects to the next step, and during retraction, the object is detained with step 38. Thus transportation is conducted through this reciprocation one after another. At this time, a thin and long object is oriented in the width direction of guide path to assure easy detention with the step 38, whereby sure transportation is accomplished.

Title: Overload detector
Inventor: OGINO MASANORI
IPC: H04N5/57
Filed: 1980-10-07
Abstract: PURPOSE:To prevent the focus deterioration of a CRT, by connecting a transistor (TR) in parallel between the base and the collector of a TR provided in a picture signal processing circuit to obtain an overload detection signal. CONSTITUTION:A luminance signal - Y supplied to a TR1 is supplied to an output TR15 to be turned into an R signal. This R signal is supplied to a CRT18 to reproduce a color picture. In this case, the high range of the R signal is compensated by an inductance 5 plus TRs 1 and 4, and accordingly the supplied - Y signal is supplied to a TR15 with its high range part emphasized according to the rise of frequency to compensate the attenuation at a high range that is caused by a stray capacitance 17. When the collector voltage of the TR4 drops to a level near zero, a detecting TR7 conducts. Thus a detection signal production control TR10 conducts to give the short circuit to the inductance 5. This prevents the supply of an excessive amount of current to the CRT18.
