Patent JP-H01313885-A (JP)
Title: High-frequency power circuit
Inventor: IWAI TOSHIAKI
IPC: H02M3/28
Filed: 1988-06-13
Abstract: PURPOSE:To restrain excessive switching element voltage and currents generated immediately after magnetron oscillation, and reduce the cost of a switching element by limiting an on-time range before the magnetron oscillation with an on-time limiting part to an ordinary on time range after the oscillation. CONSTITUTION:A control part 21 for making the on/off control of a switching element 3 is constituted with the addition of an on-time limiting part 22. This on-time limiting part 22 limits an on-time range to the predetermined value even before the oscillation of a magnetron 6. When the aforesaid limit value is set to an ordinary on time range after the oscillation of the magnetron 6, the fluctuating of the on-time range before and after the oscillation becomes small. Consequently, a current and voltage applied to the switching element 4 is restrained nearly to a steady operation state. According to the aforesaid construction, excessive voltage and currents are not generated even immediately after the oscillation of the magnetron 6 and it becomes possible to keep the rating of the voltage and currents at a level necessary for ordinary operation, thereby enabling the cost reduction of the switching element 3.

Abstract: PURPOSE: To slacken a film by rotating a tension load motor in the normal direction by discriminating a film reel wound with the film in the different direction. CONSTITUTION: The winding direction of a movie film 1 wound around a film supply reel 11 is discriminated by a supply-side tension detection part 21 which detects the tension of the movie film 1 unwound from the film reel 11. Then a supply-side reel drive motor 42 is so controlled by a system control part 4 as to retate in the same direction as the winding direction of the movie film 1.

Title: Malfunction detector for elevator
Inventor: MIYANISHI YOSHIO
IPC: B66B5/14
Filed: 1988-06-14
Abstract: PURPOSE:To keep off any increase in a starting impact even at a time when a load detecting signal comes abnormal by compensating this load detecting signal according to a difference between output of a load variation detecting means and that of a load variation predictive operational means. CONSTITUTION:A load variation detecting means 21 inputs a load detecting signal 8a and detects the maximum value of a variation portion of this load detecting signal 8a during travel of a cage. A load variation predictive operational means 22 predictively operates the maximum value of the variation portion of the load detecting signal 8a during travel by the load detecting signal 8a during stoppage of the cage and the preset maximum acceleration. Then, a compensating means 23 compensates the load detecting signal 8a according to a difference between output of the load variation detecting means 21 and that of the load variation predictive operational means 22, while a speed control operational means 24 generates a current command signal 10a by a speed command signal 9a and a speed signal 7a. With this constitution, even at a time when the load detecting signal 8a comes abnormal, any increase in a starting impact is preventable.

Title: Binary redundant sd code converting/subtracting method and its circuit
Inventor: NAKANISHI TADASHI
IPC: G06F7/505
Filed: 1987-06-12
Abstract: PURPOSE:To ensure the working of the titled method at a high speed by performing the binary redundant subtraction for the highest level digits 1 and 0 of the value shown in a complement code of 2 after adding the binary redundant SD codes +1 and -1 to the digit higher than the highest level digit by one step. CONSTITUTION:In case all digits of the value (= u) shown in normal complement series code of 2 are equal to 0, they are replaced with -1 and then with +1 if they are equal to 1 respectively. For the digit higher than the highest level digit by one step, +1 and -1 are added if the highest level digit of the unconverted complement series code of 2 is equal to 0 and 1 respectively. Thus it is possible to obtain the value (v) shown in a deformed binary redundant SD code having a larger digit number by an amount equal to a single digit. Such a deformed binary redundant SD code is used for execution of the binary redundant subtraction. Thus each digit is converted into a binary redundant SD code consisting of only +1 and -1 excluding 0.

Filed: 1990-06-05
Abstract: PURPOSE:To efficiently and effectively utilize a storing means by judging it from a transmission message having a transmission data, node designation data and address designation data that the message is transmitted while being addressed to a reception part itself. CONSTITUTION:As information to transmit the transmission message, a transmission data 13 is formed while including a node designation data 11 to designate a communication equipment as a receiving destination and an address designation data 12 to designate an address for storing the transmission data. When the transmission message is received, the reception part of the communication equipment judges it from the node designation data 11 whether the transmission message is addressed to the reception part itself or not, and when it is judged that the transmission message is addressed to the reception part itself, the transmission data is stored in the address designated by the address designation data 12. Thus, it is not necessary to register information for discriminating whether the received transmission message is addressed to the reception part itself or not, and the storing means is efficiently and effectively utilized.

Filed: 1991-05-22
Abstract: PURPOSE:To reduce integrated power consumption considerably by devising the system such that power consumption in subscribers per one line is not increased even when number of terminals connecting to one line is increased. CONSTITUTION:Only an ISDN terminal equipment 111 has a pre-heat power supply 102 alive at all times among plural ISDN terminal equipments 111,112...118 accommodated in a network terminator 100 via an ISDN line 140.

The cut belt 16 is not slackened at all even if raw material powder 4' is placed thereon by the pulling effect of the rolls 15 and the revolution braking effect of the winder 13. This state is maintained during the belt exchange operation. A pulling jig 11 is then mounted to the cut end of the bet 16 and the rolls 5 and the winder 13 are driven to move the belt 16 and the let off the belt 6 simultaneously. A winch 9 is operated in synchronization therewith to draw the belt 16 to the outside of the system and to wind the same. The belts 6 are welded to each other when the belts 6 overlap on each other on the bench 7. The belt 16 is cut from the belt 6 and the exchange operation is completed.

Inventor: YAMAZAKI TAKASHI
IPC: G06F9/46
Filed: 1987-06-11
Abstract: PURPOSE:To facilitate the test of priority interruption by bringing the state similar to the state that plural peripheral equipments give an interrupt request to a CPU simultaneously independently of the presence of an interrupt request from the peripheral equipments in giving a prescribed test signal. CONSTITUTION:In conducting the test of priority, at first a test signal TEST is made active (H). Thus, interrupt signals Ta-Te for test are fed to an interrupt control circuit 4 via OR circuits 6a-6e. The signal is sent forcibly independently of the presence of the actual production of interrupt signals INTa-INTb. Since this state is similar to the state when viewed from the interrupt control circuit 4 that the peripheral equipments 2a-2e give the interrupt request simultaneously, the CPU 1 receives the interrupt command signal INT in response to the signal Ta for test based on the interrupt priority stored in the inside.
