Title: Switching regulator
Inventor: KOBAYASHI TADASHI
IPC: H02M3/338
Filed: 1990-08-14
Abstract: PURPOSE:To enhance power conversion efficiency without causing power loss due to dissipation of heat by absorbing a spike voltage, produced through switching operation, by means of a capacitor and discharging the capacitor immediately thereafter thereby returning the spike voltage back to a power supply and further transferring to the secondary. CONSTITUTION:Upon switching of a switch circuit 1 from ON to OFF (at time t2), voltage Vc rises to turn a diode D61 ON to feed a capacitor C6 with a charging current thus increasing a current IC6 instantaneously. A current ID begins to flow through a secondary winding NS at time t2 and a voltage is induced in the base winding NB in the direction for turning the transistor Q5 in a switch circuit 5 from OFF to ON. At that time, a diode D62 is turned ON to discharge excessive charges from the capacitor C6. The charges are fed to an input capacitor Co to be utilized again in power supply and further fed to the secondary.

Title: Hanging device for displacement absorbing joint in piping facility
Inventor: MURANO TAKASHI
IPC: F16L27/12
Filed: 1997-07-28
Abstract: PROBLEM TO BE SOLVED: To simplify construction and execution and prevent a piping and a joint from being burdened by external force such as earthquake by hangingly providing a displacement absorbing joint movably in all the horizontal azimuth by a guide means installed on either a foundation or a structure body. SOLUTION: When earthquake happens and displacement in the horizontal direction is generated between pipings P1 and P2, a connecting bent pipe is pulled properly in the horizontal direction according to the displacement through flexible pipes 1 and 2. A handing rod 7 hanging the connecting bent pipe 3 can freely move along a movable pipe 6 in the lengthwise direction (to be set in the X-direction), further the movable pipe 6 can freely move in the direction squarely crossing to the X-direction (in the Y-direction), in addition, because a hanging rod slide member 7a is constituted rotationally movable against the connecting bent pipe 3, when the connecting bent pipe 3 is pulled in the horizontal direction, it is freely moved in the pulling direction without resisting the pulling force.  Hereby there is no possibility to generate immoderate stress on a piping or a connection construction.

Title: Portable terminal equipment
Inventor: ADACHI TADASHI
IPC: H04W36/00
Filed: 1996-08-15
Abstract: PROBLEM TO BE SOLVED: To reduce futile power consumption. SOLUTION: When synchronization with the control channel of a private base station can not be established within a prescribed time after turning on a power source, a communicating state is shifted to the receiving state of the control channel of a public base station. When synchronization with the control channel of the public base station, the state is shifted to a stand-by state by the control channel. When this stand-by state continues a fixed time, not-moving of a telephone equipment is judged and it is possible that the equipment exists within the area of the business base station. Then, the stand-by state is shifted to the state of receiving the control channel of the business base station (ST14).  When synchronization with the control channel can not be established in the state of receiving the control channel of the private base station (ST12 to 18), it is judged that the equipment does not exist near the area of the business station, and the receiving state is shifted to the state of receiving the control channel of the public base station (ST19). When synchronization with the control channel of the public base station is established, the stand-by state by the control channel of the public base station is continued until the step-out of synchronization (ST20 to 24).

Title: Motor drive circuit
Inventor: SHIMODA MASAMICHI
IPC: H02P6/28
Filed: 1990-08-16
Abstract: PURPOSE:To suppress fluctuation of the collector-emitter voltage of a transistor by providing means for comparing the collector-emitter voltage with a reference voltage to produce a switching signal and varying the resistance of an emitter driving current detecting resistor according to thus produced switching signal. CONSTITUTION:When a motor enters into steady state rotation, the temperature rises and the load decreases and thereby the collector-emitter voltage of an NPN transistor increases. Consequently, a control section 1 detects a switching control signal G0 and an N-channel MOS transistor 31 is turned OFF by a switching signal G1 whereby the emitter voltage VE is increased and the collector-emitter voltage of NPN transistors 21, 22, 23 decreases thus preventing heating thereof. When a heavy load is applied on the motor due to fluctuation of power supply voltage, the collector-emitter voltage of the NPN transistor decreases. Consequently, the N-channel MOS transistor 31 is turned ON by the switching control signal Go and the collector-emitter voltage is increased thus preventing saturation.
