Patent JP-S59221672-A (JP)
Title: Current detecting circuit
Inventor: GOTOU HIROSHIGE
IPC: G01R19/15
Filed: 1983-05-31
Abstract: PURPOSE:To make a high-speed response possible by feeding constantly a constant-bias current to a current detecting circuit consisting of MOSFETs connected in series. CONSTITUTION:Field effect transistors MOSFETs 1 and 2 applied with bias voltages VB1 and VB2 are connected in series, and a signal current source 4 and a bias current source 6 are connected to the source of the FET2. Further, a reference power source is connected to the drain of the FET1, and a source follower circuit 5 is connected to the connection point between both FETs 1 and 2. When the signal current of the signal current source 4 and the bias current of the bias current source 6 are denoted as I and IS respectively and the gate potential of the FET1 is represented as V, the source potential VS of the FET2 is as shown by an equation (where A is a constant, L is the gate length of the FET1, and W is the gate width of the FET2), so the signal current I is calculated. Then, even when the signal current I is zero, neither of the FETs 1 and 2 enters a floating state because of the bias current IB, and a high-speed response is made possible.

Title: Voltage-current converting circuit
Inventor: UEDA MASAZUMI
IPC: G05F1/56
Filed: 1988-04-19
Abstract: PURPOSE:To form a voltage - current converting circuit having an ideal limiting characteristic by providing a current limiting circuit consisting of an error amplifier for amplifying a difference between an output of a differential ampli fier and a reference voltage. CONSTITUTION:When an input voltage VIN is smaller than a reference voltage 13, an output of an operational amplifier 12 becomes a saturated state, and a diode 14 becomes non-conduction. Accordingly, the existence of a current limiting circuit consisting of the operational amplifier 12, the diode 14 and the reference voltage 13 is not concerned in a voltage-current conversion at all and the conversion is executed. However, when the input voltage VIN exceeds the reference voltage 13, the diode 14 is driven. Accordingly, a base current of a transistor 3 being a current buffer decreases and an emitter current, namely an output current IOUT decreases. The output current in this case becomes that which has been limited by the reference voltage 13.

Title: Automatic tracking device for magnetic recording and reproducing device
Inventor: NISHIBAYASHI ATSUSHI
IPC: G11B15/467
Filed: 1987-04-20
Abstract: PURPOSE:To surely obtain the optimum tracking value in a short time and with high accuracy by initializing the start point for the change of a tracking phase and designating an optional output level difference rank to the maximum reproduction output level. CONSTITUTION:The video signal that converges in a short time and with high accuracy to the tracking convergence value and has a high S/N and the high resistance to the disturbance is obtained through the tracking initialization, decision of the change direction and calculation of the optimum value. For instance, the tracking phase value of a servo circuit 9 is initialized at the value tQ with which an optimum image is obtained in an SP state for example. Then the tracking phase value of the circuit 9 changes at every DELTAt toward the smaller tracking phase value by a command of a microcomputer 7 simultaneously with start of the reproduction. Thus the reproduction outputs H0, H1...H8 obtained sequentially are processed by an envelope wave detecting circuit 5 and an A/D converter 6. The front and back levels of the reproduction output are compared with each other within the computer 7. Thus the maximum value H8 is set.

Title: Radio receiver
Inventor: KURODA KEIICHI
IPC: H04B1/10
Filed: 1984-05-15
Abstract: PURPOSE:To prevent sound-cut from being generated due to a variation of an input signal level by providing an independent comparator on a squelch circuit and a scan controlling circuit, respectively, and making a threshold for applying a squelch smaller than a threshold for applying a scan stop. CONSTITUTION:By each variable resistor 15, 16 of a single spindle two-throw variable resistor 17, the threshold value of comparators 13, 14 is set so that the threshold of the comparator 13 is always smaller than the threshold value of the comparator 14. An input signal level of a receiver detected by a level detecting circuit 7 is supplied to the comparators 13, 14, and scanning is continued in a state that a gate circuit 10 remains closed until said level exceeds the threshold value of the comparator 14. When the input signal level exceeds a level of the comparator 14, a controlling circuit 12 is operated and the scan is stopped, and a reception is executed by opening the gate circuit 10. The threshold value of muting by a squelch is smaller than the threshold value of a scan stop, therefore, sound-cut is not generated even in case an input is varied to some extent.

Title: Production of colored ceramic product
Inventor: KUNO HIROAKI
IPC: C04B41/48
Filed: 1989-04-17
Abstract: PURPOSE:To obtain colored ceramic product readily and effectively dyeable at desired color even inside of product by impregnating ceramic sintered material having continuous pore with dye-containing resin and curing. CONSTITUTION:Dye-containing resin is contained in a ceramic sintered material having continuous pore and cured to afford a colored ceramic product. As used ceramic sintered material, ceramic sintered material composed of CaO, SiO2 and MgO surrounded by points 1, 2, 3, 4, 5, 6 and 7 shown in the figure is suitable. Porosity of the ceramic sintered material is preferably about 5 to 50% expressed by water absorption from the viewpoint of-impregnating property of the resin. Sufficient resinimpregnating property is not obtained and colored degree is insufficient in a case of <=5% water absorption. On the other hand, in a case of >=50% water absorption, production as a sintered material is difficult and properties as ceramic are in danger of being spoiled as ceramic part within the product is reduced.
