Abstract: PURPOSE:To accurately read a bar code pattern despite the variance of the distance set between a sensor and an object in a magnetic coded information recognizing method by detecting the pahse difference between a reference signal and the synthetic value of the mutual induction voltage of the secondary coils are generated by the primary boils which are excited by the reference AC signals of different phases. CONSTITUTION:The primary coils 4a and 4b are excited by the AC signals having a phase difference pi/2 and scan the edge parts of cores 41 and 42 with approximation to an object 11. The mutual induction voltage of a fixed amplitude is induced at a secondary coil 4c of the core 41. Meanwhile a magnetic circuit having the magnetic resistance accordant with the patterns 11a and 11b is formed on the scan path of the core 42. Then the mutual induction voltage whose amplitude varies according to the change of the magnetic resistance is induced at a secondary coil 4d. Then the synthetic secondary voltage of the mutual induction voltage of both coils 4c and 4d is compared with a prescribed reference level as a phase difference signal at a comparison part 39 via an amplifier 36, a zero-cross circuit 37, and a latch circuit 38. The phase difference signal is outputted as a pulse signal P1.

Title: Substrate supporting device
Inventor: OKAZAKI HISAKO
IPC: H05K7/14
Filed: 1995-02-17
Abstract: PURPOSE: To support a second board connected to a first board in a prescribed state in which the second board can be easily disconnected from the first board by independently supporting the second board by means of first and second supporting means so that part or entire body of the second board can be moved against the first board in first and second directions within a prescribed extent. CONSTITUTION: When a card 1 connected to a mother board 4 is largely moved upward, a first board rail 11 is bent upward due to an upward force applied through the upper end section of the card 1. When the card 1 is largely moved downward, on the other hand, a second board rail 12 is bent downward due to a downward force applied through the lower end section of the card 1. Therefore, the card 1 can be largely swung in the vertical direction as compared with the conventional case where the card 1 is fixed to the mother board 4 by the independently movable amounts of the rails 11 and 12 in the upward and downward directions.

Abstract: PURPOSE:To control the value of gamma by using a bias of a substrate by a method wherein a carrier in a gate region is made to flow to the substrate through a buried layer and its amount is controlled by a potential of the substrate. CONSTITUTION:An SIPT is an n-channel SIPT where an n<+> region 21 is used as a source, n<+> regions 22 are used as drains, p<+> regions 23 are used as gates and an n<-> region 24 is used as a channel region; it is formed on p<+>/p<-> substrates 25, 26.

That is to say, channels 28 between the n<+> regions 22 are depleted by a diffusion potential of the n<+> regions 22; the amount of its potential is controlled by potentials of the n<+> regions 22 and the p<+> substrate 26 in an electrostatic induction manner. By this setup, it is possible to change the value of gamma by using a bias voltage of the substrate.

Abstract: PURPOSE:To avoid unnecessary stoppage of a steam producing plant even when the turbine speed fluctuates by sending an open signal to a breaker in accordance with the load quantities before and after the load is disconnected and a selection controlling rod actuating signal. CONSTITUTION:When load disconnection occurs and a power load unbalance relay is actuated, a system stabilizing device 55 limits the load by opening a prescribed number of breakers (some of 58-62) connected with a load line so that the system load can become a certain value (for example, 20%) a prescribed time (for example, 1.0sec) under a condition where selection controlling rod insertion (SRI) actuating signals 71 and 72 are available and the then load quantity of a BWR plant is a certain value (for example, 20%) or higher and the load at the moment when the power load unbalance relay is actuated is a certain value (for example, 70%) or higher. Therefore, even when the turbine speed fluctuates due to a disturbance in a power system and the turbine speed is to be reduced to a moderate speed, the operation of a steam producing plant can be continued by avoiding unnecessary stoppage of the plant.

Title: Color saturation control circuit
Inventor: MIZOGAMI HIROYUKI
IPC: H04N9/64
Filed: 1993-03-15
Abstract: PURPOSE:To make noise of a color signal unremarkable when an antenna input voltage is low by controlling color saturation with an output voltage of a SECAM identity discrimination circuit. CONSTITUTION:A SECAM color signal given to an input terminal 1 is amplified by a SECAM limiter amplifier 2. An identity discrimination circuit 12 receives a SECAM color signal subjected to limiter amplification from the amplifier 2 to make identity discrimination. The circuit 12 is active only for a period of a gate pulse given from a terminal 11 and its detected current is smoothed. The DC voltage is compared with a DC voltage of a reference voltage source 15 at a voltage comparator 14 and when an output voltage of the circuit 12 is lower than a voltage of the voltage source 15, the comparator 14 controls a color saturation control circuit 6 to allow a color difference matrix circuit 7 not to provide a color difference signal output. Furthermore, when the output voltage of the circuit 12 is lower than the voltage of the reference voltage source 17, the voltage comparator 16 controls the circuit 6 to decrease color saturation.

Filed: 1989-03-07
Abstract: PURPOSE:To avoid the display of a signal not suitable for viewing by providing a function discriminating and executing whether or not a signal inputted at present is to be displayed as a TV signal through the input of a control signal. CONSTITUTION:A TV signal reproducer 11 outputs a control signal 14 representing the reproduction and output to a television receiver 12 while the recorded TV signal is reproduced and outputted and the receiver 12 uses a control signal from the reproducing device 11 to display the input signal as the TV signal. On the other hand, when the reproducer 11 cannot reproduce and output the TV signal to be recorded to the receiver 12, the receiver 12 discriminates the signal 14 representing it by a discrimination means 121. The discrimination output controls the switching means 122 to stop the display of the signal from the reproducer 11 as the TV signal. Then the signal is switched into a TV signal such as an external input signal inputted via a terminal 123 from other TV signal reproducer prepared in advance and the selected signal is displayed for the viewer.

IPC: C09D175/00
Filed: 1989-03-07
Abstract: PURPOSE:To obtain both good video characteristics and audio characteristics and to improve traveling durability by using specific binders respectively for first and second magnetic layers. CONSTITUTION:The magnetic recording medium consists of a nonmagnetic supporting body and the first and the second magnetic layers each comprising ferromagnetic powder dispersed in a binder and formed in this order on the substrate. The binder used in the first magnetic layer contains vinyl chloride copolymers with 2 X 10<-4> to 5 X 10<-3>eq/g functional groups, while the binder used for the second magnetic layer contains vinyl chloride copolymers with 3 X 10<-5> to 2 X 10<-4>eq/g functional groups. The former binder contains larger amount of functional groups than the latter by over 2 X 10<-5>eq/g. Thereby, the second magnetic layer to which a head directly contacts has good dispersibility and solubility. By improving the solubility, the surface roughness of the first magnetic layer can be suppressed. Since good audio characteristics can be obtained by high density packing, the amt. of functional groups in the first magnetic layer is made large to a certain extent.
