Abstract: PURPOSE:To reduce the over-wrapping amount of a tape and to prevent a drum motor and a motor driving circuit from being destroyed due to an overcurrent by applying current limiter on the motor driving circuit after completing servo lock on the drum motor. CONSTITUTION:When the drum motor 1 is set at a constant rotating state and the servo lock is completed, a current limiter control means 4 detects the fact, and starts the operation of the current limiter of the motor driving circuit 2. Therefore, a motor driving current is suppressed compulsively less than a limiter current value after the servo lock is completed, and the driving current can be prevented from being increased exceeding the limiter current value even when an accident in which the tape stuck occurs and the motor driving current is increased. Thereby, the start-up torque of the drum motor 1 can be decreased, and the wrapping amount of the tape can be decreased due to the accident in which the tape is stuck, and also, it is possible to prevent the drum motor 1 or the motor driving circuit 2 from being destroyed due to the overcurrent.

Filed: 1980-05-27
Abstract: PURPOSE: To realize evenness of the cooling effect of an evaporator by attaching a bimetal valve, which operates when the coolant temperature inside the evaporator becomes above a certain value, to a suction slot valve which is employed in a  coolant flowing line of an air conditioner for an automobile etc.  
     CONSTITUTION: A bimetal valve 19 is attached to a partition wall 13 to form a second control section so that a opening 13a can be closed/opened. Said bimetal valve 19 opens said opening 13a when a coolant temperature becomes over 0°C, and closes the opening 13a below 0°C. When the coolant temperature rises over 0°C, a large amount of coolant flows into a compressor side through the opening 13a, bellows room 21, and a groove 18a of a supporting body, for the coolant pressure inside the evaporator to becomes lower. Thus by means of the above mechanism, a large quantity of coolant can be made to flow into the compressor side  when the coolant temperature inside the evaporator becomes high, and the evenness  of the evaporator cooling effect can be realized.

Title: Automatic frequency controller
Inventor: HAYASHINO YUJI
IPC: H04J1/00
Filed: 1996-03-26
Abstract: PURPOSE: To provide an automatic frequency controller which can find an accurate frequency error and can quickly control the frequency with high accuracy. CONSTITUTION: A pilot signal (having the known phase information and a prescribed length) is put into the signal sent to the receiver side from the transmitter side at every prescribed time interval. An inverse tangent arithmetic circuit 22 calculates the inverse tangent of the pilot signal contained in the received signal to decide the phase of the pilot signal. A phase error arithmetic circuit 24 calculates the phase error between the known phase information stored previously in a memory 23 and the output of the circuit 24. A linear approximation circuit 25 regards the output of the circuit 24 as a linear function of time and directly approximates to it. A frequency error arithmetic circuit 26 calculates a frequency error based on the tilt of the output of the circuit 25.  Then the oscillation frequency of a variable frequency oscillation circuit 27 is controlled in response to the calculated frequency error. Thus the frequency can be automatically controlled at a high speed and with high accuracy.

Title: Resin member for lower part of vehicle
Inventor: NAGATA TAKUJI
IPC: B60R13/04
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To sufficiently absorb collision energy, regardless of the size of the diameter of a pebble by forming a crimp pattern having random patterns which are different in depth and width on a surface on which the pebble collides. SOLUTION: A large crimp 1 which is wide and deep and a small crimp 2 which is narrow and shallow are formed at random on the surface of a resin member. When a pebble having a large diameter collides with the surface of the resin member, impact energy of the pebble colliding with the large crimp 1 is absorbd by elastic deformation of the projecting part of the large crimp 1. When the pebble having a small diameter collides with the surface of the resin member, impact energy of the pebble colliding with the small crimp 2 is absorbed by elastic deformation of the projecting part of the small crimp 2. Thus, impact energy due to collision of pebbles and sand can be efficiently absorbed and noise at the inside/outside of a compartment can be reduced by suppressing generation of abnormal sound due to vibration of the resin member.

Abstract: PURPOSE:To simplify the structure, to reduce the manufacturing costs and to improve detecting sensitivity, by forming a heat sensitive resistor film and a pair of electrode films on each of the front and back surfaces of a flat insulating substrate as a thermal resistor body, thereby constituting a heat flow sensor. CONSTITUTION:On one of the two parallel surfaces of a flat insulating substrate 5 (e.g., ceramics and glass) as a thermal resistor body, a heat sensitive resistor film 6 and a pair of electrode films 7 and 7' are formed. On the other surface thereof, a heat sensitive resistor film 8 and a pair of electrode films 9 and 9' are formed. Thus an intended heat flow sensor is constituted. The temperature difference between the front and back surfaces of the flat insulating substrate 5 as the thermal resistor body is detected highly sensitively as the difference in resistance values of the heat sensitive resistor films 6 and 8. Therefore the heat flow can be detected highly sensitively. As the heat sensitive resistor films 6 and 8, an oxide resistor film or a carbide resistor film, which has excellent heat resisting property and the like, is suitably used.
