Title: Checking device of record content of recorded magnetic tape
Inventor: KOMAZAKI KATSUJI
IPC: G11B5/86
Filed: 1984-03-30
Abstract: PURPOSE:To attain accurate and stable check of the record contents of a magnetic tape with no dependence on the human aural sense, by converting the record contents of a recorded magnetic tape to be checked into digital data for comparison with the reference data. CONSTITUTION:When a magnetic tape is reproduced at an n-fold speed (8 times) as high as a normal reproduction speed, the output of a reproduction head 1 is supplied to a filter 16 via an amplifier 15 to extract the component of 1kHz with a center frequency 8kHz. This output of extraction is sent to an envelope detector 17 and converted into the digital data by an A/D converter 3A through a sampling/holding circuit 18. The reproduction output of the head 1 is supplied to a filter 20 after amplification, and a cue signal is extracted. The cue signal of 7Hz is extracted with a center frequency 56Hz of the filter 20 and undergoes the waveform shaping through the level comparison of an analog comparator 4A. A CPU21 supplies these results to an input port 23 and delivers the result of the reading check to a display device 30 via an output port 27. Thus the accurate decision is secured since the record contents of a magnetic tape are converted into the digital data for comparison with the reference data.

Title: Semiconductor integrated device
Inventor: FUJIKAWA TSUNEO
IPC: H01L21/8246
Filed: 1985-03-27
Abstract: PURPOSE:To expand the range of an operating power source voltage, by imparting a reference voltage to a gate, imparting a power source voltage to a drain, imparting an operating voltage to an inner circuit from a source in NchFETs, and turning ON a PchFET, which detects the power source voltage and sends the power source voltage that is applied on the source to the inner circuit. CONSTITUTION:NchFETs Q2 and Q3 are connected in series through the diodes and grounded, and a reference voltage 2Vth is formed. A power source voltage VCC is applied through a PchFET Q1, which is grounded through the gate and has a high resistance value. The voltage 2Vth is applied to the gate of NchFET Q4. The VCC is applied to the drain of the Q4. The VCC is sent to a ROM through the source. Before the VCC is decreased to the lower operating voltage limit VCC'+Vth(Q4) of the ROM, the voltage (chain line) divided by resistors R1 and R2 becomes lower than a logical threshold-value voltage VLT of an inverter IV. A Q5 is turned ON by the output of the IV. In the Q5, the VCC' becomes about the same value of the VCC without level loss such as seen in the Q4. Thus detection is performed before the operation of a constant voltage circuit becomes unstable, the VCC itself is supplied, and the range of the operating power source voltage is expanded.

Title: Icemaker
Inventor: TAKANISHI HIDETOMO
IPC: F25C1/24
Filed: 1994-03-30
Abstract: PURPOSE:To prevent putrefaction and offensive odor of water by reducing the chance that water is in contact with the air in a water supply passage by the functions of a self-priming pump attached to a water supply tank, a funnel-like member covering a periphery of a discharge tube, and a containing member having a filter at the bottom of the tube, etc. CONSTITUTION:Automatic water supply is executed by a control circuit function. A water supply timer is started, and the motor of a pump 6 is forward rotated. Water is directly sucked from a water supply tank 7, and introduced into the pump 6 through a sucking tube inserted into the tank 7 and tube joints 35, 71. The water is discharged from a nozzle 13 via a tube 9. When a first water supply timer is fully counted, the pump 6 is switched to reverse rotation to stop discharging of the water. In this case, an icemaking tray 2 is fully filled with water. A second water supply timer is started, and the motor is reversely rotated. Since residual water in the tube 9 is recovered to the tank, the water of the tray 2 is frozen, ice is released by an inverter 3, and dropped in an ice storage vessel 5. The opportunity of contact of the water with the air in this cycle is reduced.

Abstract: PURPOSE:To improve collating accuracy with the use of a simple processing by executing the sum of product operation between an output at every picture element of an input picture and a weight concerning the output, and a threshold processing operation for the output of the sum of product operation by means of a neural network part. CONSTITUTION:A neural network circuit 6 executes the sum of product operation between the output at every picture element to have image-picked-up of an indefinite individual and the weight concerning the output, and a threshold processing for the result. The difference between an output Yj of the circuit 6 and a desirable value Yj0 corresponding to the output Yj is obtained, and the output Yj is fed back to the circuit 6. A deciding part 7 compares the output Yj of the circuit 6 with a prescribed value K concerning the registered individual, when only one Yj, whose value is >=K, exists, the individual is identified as the registered one. When the Yj is <K or >= the two individuals exist, the individual is decided not to conform to the registered one. Thus based on the highly reliable physical information of the individual, the collation accuracy is improved by the simple processing.
