Title: Semiconductor circuit breaker
Inventor: SHIMIZU YASUHIRO
IPC: H02H5/04
Filed: 1989-04-12
Abstract: PURPOSE:To interrupt overcurrent in a wide range accurately by driving the current of a semiconductor interrupting element according to the result of AND of the value of the current flowing through the semiconductor interrupting element and the signals representing the temperature difference between the semiconductor interrupting element and a cooling plate. CONSTITUTION:By turning ON and OFF a semiconductor interrupting element 2 in an interrupted line 1 the flowing current IL is detected by a current detector 4, inputted into the 1st comparator 5 and compared with the reference current (a). On the other, the temperature Tc of a temperature-controlled cooling plate 3 and the temperature Tj of the semiconductor interrupting element 2 are detected by temperature detectors 6 and 7 and inputted into an operating amplifier 9. The difference between Tc and Tj is found, inputted into the 2nd comparator 10 and compared with the reference value (b). The outputs of both comparators 5 and 10 are inputted into an AND circuit 11, with the output of which the ON-OFF of the semiconductor interrupting element 2 is controlled. Accurate and appropriate interruption is thereby made against the overcurrent exceeding twice as much as the rated current and the current slightly exceeding the rate but lasting.

Title: Control system for reel driving motor
Inventor: TEZUKA AKIO
IPC: H02P7/06
Filed: 1981-06-16
Abstract: PURPOSE:To reduce motor capacity by a method wherein the field flux and the armature current are effectively utilized as far as the maginal values respectively. CONSTITUTION:When a line starts operation, an arithmetic controlling device 5 transmits reference field flux PHIREF to a field current/flux converter 6 so that the maximum field current may be supplied simultaneously transmitting reference armature current IREF to an armature current power supply 2. Next when armature voltage reaches the rated voltage, the arithmetic controlling device 5 diminishingly controls the field current by means of calculating the reference field flux PHIREF so that said armature voltage may not exceed said rated voltage. Moreover when the armature voltage is the rated voltage and the field flux becomes the weakening flux, the arithmetic controlling device 5 transmits the material velocity limiting signal to the material velocity arithmetic unit 7 in order to decelerate the material velocity so that the material velocity may not exceed the maximum revolution of the motor at this time.

Title: Photodisc recorder and operation thereof
Inventor: WAAREN REROI BURETSUCHIYAA JIY
IPC: G11B7/125
Filed: 1990-04-10
Abstract: PURPOSE: To facilitate reading of recording signal and to improve the reliability in reading recording medium by correcting the laser pulse period after adjusting power level at the time of a reading operation corrected in the innermost track. CONSTITUTION: The power of laser 67 is adjusted for the asymmetry in a reading signal using a test pattern, in the innermost track 110 in the radial direction among a number of tracks of a magneto-optical disk 30. Following this adjustment, plural pulse period adjustments are performed against tracks 110-114 arranged in the radial direction. Since change in the pulse period of a recorded signal pattern shows non-linearity through the recorded band of the magneto- optical disk 30, if an almost linear change is generated, the correction tracks 110-114 can be further reduced. However, if a large non-linear change is generated, a larger number of correction tracks must be used. As a result, reading of a recording signal can be easily performed, enabling reliability in reading a recording medium to be improved.

Title: Logic circuit unit using metal/semiconductor field effect transistor
Inventor: SATOU TOSHIROU
IPC: H03K19/00
Filed: 1984-05-10
Abstract: PURPOSE:To reduce the power consumption of an output function by adding a source follower type level shift circuit to the input side without lessening the features of an artificial complementary output function of a conventional logic circuit unit and then reducing the load in an output mode of ''1'' of the output function. CONSTITUTION:A source follwer type level shift circuit consisting of TR5 and 5a, D and Da and TR6 and 6a is added to a conventional input terminal. The gates of the TR5 and 5a are replaced with new input terminals IN10 and IN10a. When an OUT10 is kept at ''1'', a Schottky diode function produced between the gate and the source of the TR5a serving as the load side and the forward voltage drop of the Da are impressed to the Schottky diode voltage produced between the gate and source of conventional TR1a and TR4a. Then the gate width of the TR5 and 6 are set at proper levels. Thus conventional 0.7V can be increased up to a range of 1.4-2.1V and therefore an I10 can be set substantially at ''0''. Therefore the output current of the OUT10a is always kept at ''0'' in terms of DC.

Title: Search stop circuit
Inventor: OKUMURA HACHIROU
IPC: H03J7/18
Filed: 1983-05-26
Abstract: PURPOSE:To attain search stop as desired and to prevent malfunction by using a signal in response to an electric field strength of a receiving signal and an intermediate frequency signal at a prescribed level counted accurately so as to generate a search stop signal. CONSTITUTION:When a detected output signal is applied to an input terminal 16, a control signal in response to the electric field strength is generated at an output of a control signal generating circuit 17. An input transistor (TR)18 is turned on in case of a broadcast station having a large electric field strength, an output signal of a limiter amplifier circuit 14 is applied to a stop signal generating circuit 15 only during the period when a bypass TR19 is turned off and the frequency is counted. On the other hand, in case of a broadcast station having a small electric field, the TR18 is turned off and the TR19 is turned on. Then, an output signal of the circuit 14 is bypassed by the TR19 and not applied to the circuit 15. Thus, no search stop signal is generated from the circuit 15 and the automatic searching is not stopped in the broadcast station having the small electric field strength and the automatic searching is conducted succeedingly.

Filed: 1991-04-24
Abstract: PURPOSE:To increase the calculating speed of a double loop by comparing the node numbers with each other between the layers adjacent to each other and defining the layer having the larger number of nodes as an inner loop. CONSTITUTION:A forward loop control part 106 decides the inner and outer sides of the double loop calculation every layers adjacent to each other in a forward calculation state. Meanwhile a backward loop control part 107 decides the inner and outer sides of the double loop calculation every layers adjacent to each other in a backward calculation state. Then a weight setting control part 109 sets the weight so that the weight values are referred to or updated in sequence in both forward and backward calculation states. In such a constitution, one of both adjacent layers that has the larger number of nodes is defined as an inner loop. Thus the calculating speed of a double loop is increased. Furthermore the weight values are set so that the weight values of the connection lines are referred to or updated in sequence for calculation of the double loop.
