Title: Monitor circuit of battery charging system for automobile
Inventor: ROBERUTO BERUCHIEESHI
IPC: H02J7/14
Filed: 1992-04-21
Abstract: PURPOSE: To prevent unnecessary current consumption by providing a processing comparison circuit to generate a signal for performing a control, so that a current that flows through the collector-emitter path of a drive transistor that is connected in series with the field coil of an electric generator changes as a function of the rotary speed of the generator. CONSTITUTION: A processing comparison circuit 23 in a field current control circuit 18 of a monitoring circuit conditions the conduction of a current that passes through a drive transistor T, so that the current strength that flows through a field coil in an electrical generator fluctuates according to the rotary speed of the rotor of the electrical generator. Specifically, the processing comparison circuit 23 controls the drive transistor T via a drive circuit 15 so that the drive transistor T can be driven in first and second modes. In this case, the first mode corresponds to a low value for the average peak current of the field coil when the rotary speed of the electrical generator is at a specific value or less, and the second mode corresponds to a high value for the average peak current, when the rotary speed of the electrical generator is at a specific value or more.

Title: Recording device
Inventor: ABE SHIYUNICHI
IPC: G03G15/20
Filed: 1982-06-12
Abstract: PURPOSE:To prevent a heat and a press-contacting rolls from deforming owing to press contacting by delaying the releaseing of the press contacting between both rolls by a scheduled time to stop a device after the rolls are released from the press contacting. CONSTITUTION:The press-contacting roll is pressed against the heat roll through a cam mechanism by the rotation of a motor M2. This press-contacting operation is detected by a microswitch MS1, which turns on when the press contacting ends to supply a contact signal to a control part MC; and a control signal S3 is turned off to stop the rotation of the motor M2. The signal S3 is turned on, for exapmle, 20sec after fixing operation to drive the motor M2, and consequently when the press contacting is reset, a microswitch MS2 turns on to supply a contact signal to the control part MC; and the contact of a relay RL3 is broken by the control signal S3 to stop the motor M2. Consequently, the loss time in every original replacement is prevented and the deformation of both rolls due to the press contacting is prevented.

Abstract: PURPOSE:To achieve higher reliability of a load test with a lower cost by a method wherein a test pile is formed using a shaft steel reinforcement of a hollow pipe and a rod for measurement is inserted through the shaft steel reinforcement to measure, which eliminates a protective pipe. CONSTITUTION:Shaft steel reinforcements buried into a load test pile A is built up with a hollow pipe and a rod 12 for measurement is inserted through the hollow part of the shaft steel reinforcements. A load on the test pile A is applied with the operation of a jack 8. With the extension of the jack 8, a reaction pile B is forced down while the test pile A forced up. As a result, a displacement value of the tip of the test pile A is measured with a dial gauge 16 through the rod 12 and that of a heat end of the test pile A is measured with a dial gauge 19. A tip displacement value of the load test pile B is measured with a dial gauge 17 through a rod 13. A supporting force and a circumferential surface friction force of the pile can be calculated from the measured values thus obtained. This eliminates a protective pipe for insertion of the rods thereby achieving higher reliability of a loading test with a lower cost.
