Title: Optical recording system
Inventor: MOUTAI AKINORI
IPC: G02B7/28
Filed: 1981-11-10
Abstract: PURPOSE:To compensate deviation of a focus controlling system due to fluctuations of temperature, etc., even if it occurs, and to perform main recording by correcting the focus controlling system to an optimum focus state, and performing focus control. CONSTITUTION:Beams are emitted from a light source 7 for recording and a light source 12 for reproduction, and an 8MHz signal for optimum focus determination is supplied to an optical modulator 8 for a specified time. A beam modulated by said signal is projected as a recording beam upon a recording medium 1. A program for focus correction is read out of the 1st memory 31 of a control circuit 29 and the focus of the recording beam 2 is varied with time. A focus controlling circuit 35 includes an error amplifier 38 and a driving amplifier 39 which generate a voltage corresponding to the potential difference between input terminals A and B to control a moving coil 40 coupled with a condenser lens 10. Consequently, even if a focus controlling system has deviation owing to fluctuations of temperature, etc., the deviation is compensated to perform main recording.

A continuous crystal grain boundary deposit phase forming material acts as gradient function agent of high heat conductivity material and nuclear fuel oxide. For example, addition of a material containing aluminum, etc., improves bonding property of both of them. So uranium oxide powder is pressed and crashed to be grain to which molybdenum powder and mixture of alumina and silica are added and mixed, which is compaction molded. Then, it is heated in steam flow to reduce and sintered. By this, effective heat conductivity becomes high and is maintained to high burnup.

Title: Rs flip-flop circuit
Inventor: NAKAYAMA JUN
IPC: H03K3/356
Filed: 1990-07-09
Abstract: PURPOSE:To prevent the destruction of the data held by an RS flip-flop circuit that is caused by the glitch noise by controlling the back gate bias voltage of a P channel type MOS transistor TR. CONSTITUTION:The substrate voltage of a P channel type MOS TR is controlled by noting the back gate effect of a MOB TR. In other words, the back gate effect is produced when the substrates of the P channel type MOS TR 6, 7, 10 and 11 are biased to a fixed positive potential via a control terminal 5. Then the drain currents of these TR 6-11 are reduced and therefore the charging currents flowing to the 1st and 2nd output terminals 3 and 4 are also reduced. As a result, the potentials of both terminals 3 and 4 are not satisfactorily reduced and kept at each precedent level if the period of time when a set terminal 1 or a reset terminal 2 is set at logic value 'O' is shorter than the switching speeds of the TR 6-11. Thus the data are never destroyed.

Filed: 1982-10-14
Abstract: PURPOSE:To detect the error of circuit design easily by inputting directly the data of a circuit diagram, processing the circuit diagram data by data driving type graphic language and displaying the process of simulation together with the circuit diagram.

Title: Electronic tuning type radio receiver
Inventor: MIZUNO MASATAKA
IPC: H04B1/26
Filed: 1986-07-31
Abstract: PURPOSE:To discriminate a destination for which the frequency range, separation frequency, etc., are determined by using a microcomputer which has an A/D conversion part for a control part which sets a frequency division rate. CONSTITUTION:An electronic tuning radio control IC 9 uses the microcomputer which has the A/D conversion part 91. A destination selection part 12 divides a constant voltage Vdd by resistances R1 and 2z and inputs the divided voltage to the A/D conversion part 91. When Vdd = 5 V and the A/D conversion part 91 has 4-bit resolution, a selection can be made corresponding to an A/ Dconverted 4-bit digital value. Consequently, a resistance-divided analog voltage is only inputted to an A/D conversion input terminal, so that it is considered equivalently that a destination code whose maximum number of bits is the resolution of the A/D conversion part is inputted. Consequently, one input terminal is only used regardless of the number of digits of the code, so IC terminals are utilized. Further, external constitution may be only resistances, so the hardware constitution is simple and inexpensive and made common to various kinds of equipments. 10: operation SW group, a: microcomputer with A/D converting function, b: digital value, c: analog value V.

Title: Data transfer switching system
Inventor: MORITA SUMIE
IPC: G06F15/177
Filed: 1988-07-20
Abstract: PURPOSE:To shorten time required up to the restart of data transfer after completing the switching of a system by allowing a transfer controller recognizing the state of switching in detail to set up an available state for restarting data transfer. CONSTITUTION:A switching state receding means 300 in a current transfer controller 30 recedes switching state information 200 indicating the transfer state of a data group 100 at the time of switching in a dual memory device 21. On the other hand, a switching state setting means 400 in a preparatory transfer controller 30 sets up the transfer restart state of the preparatory transfer controller 30 based on the information 200 receded in the memory device 2. Since the transfer controller recognizing the state of switching in detail sets up the available state for restarting data transfer, the time required up to the restart of data transfer after the completion of system switching can be remarkably shortened and service can be improved.
