Patent JP-S6419903-A (JP)
Title: Electric car controller
Inventor: KURIHARA HIROYUKI
IPC: B60L9/18
Filed: 1987-07-15
Abstract: PURPOSE:To prevent the temperature rise of a snubber resistor by measuring a constant-speed operation time in each pulse mode and by stopping an inverter action after the lapse of a fixed period of time. CONSTITUTION:When a master controller 6 is inputted in a constant-speed operating position, changeover switches 9 and 10 are changed over to the make and break position opposite to that shown in the drawing. Also, if a constant- speed command is given to a target speed setter 20, a vehicle speed signal fr is latched and speed command signal fp is set. On the other hand, the constant-speed command is also given to a constant-speed counter 22. The constant-speed counter 22 starts counting when the pulse mode determined by a PWM modulator 15 is that other than 1 pulse, outputs a constant-speed ineffective command 27 after the lapse of fixed period of time, and gives an inverter stop signal to inverter 2. Thus, it is possible to prevent the temperature rise of a snubber resistor generated at a constant-speed operation in other pulse modes other than 1 pulse mode.

Title: Carbon brush
Inventor: TATEISHI SHIRO
IPC: H02K13/00
Filed: 1996-07-04
Abstract: PROBLEM TO BE SOLVED: To prevent a carbon brush from being cut and the surface of a commutator from being roughened by suppressing the occurrence of chattering between the commutator and the brush by constituting the commuator slide surface provided at the front end of the brush of a commutator contacting surface having the same curved surface as the outer peripheral curved surface of the commutator and no-commutator contacting surfaces provided at both ends of the contacting surface. SOLUTION: A commutator contacting surface 2a which comes into contact with a commutator 1 has the same outside diameter R as the commutator 1 has and no-commutator contacting surfaces 2b having curved surfaces of a diameter larger than the outside diameter R of the commutator 1 are provided at both ends of the surface 2a. As a result, the edge section of a motor at which the surface 2a and surfaces 2b intersect each other becomes smoother and the occurrence of chattering between brushes can be suppressed at the initial rectifying time of the brushes 2. Therefore, the brushes 2 can obtain a stable rectifying state which is free from characteristic deterioration, because the cutting of the brushes 2 and surface roughening of the commutator 1 can be prevented.

Title: Device for preventing freezing in oil burning hot water supply machine
Inventor: TAKAHASHI TAKESHI
IPC: F24H1/10
Filed: 1990-07-02
Abstract: PURPOSE:To prevent water from freezing with the necessary minimum of the output of a heater by a method wherein a freezing prevention heater is provided near the outer attachments to a water supply pipe and a hot water supply pipe a supply water temperature detector is provided on the water supply pipe and a signal is sent from the supply water temperature detector to a controller to activate a freezing prevention heater and a vaporizing heater. CONSTITUTION:When the temperature of a water supply temperature detector 11 drops near 0 deg.C as ambient temperature decreases to about -10 deg.C, a freezing prevention heater 10 is automatically energized to raise the temperature of a water supply pipe 1 and a hot water supply pipe 3, whereby the heat is transmitted from the water supply pipe 1 and the hot water supply pipe 3 to a heat exchanger 2 to prevent the water freezing. When ambient temperature drops further to about -20 deg.C, the water temperature can not be retained not below the freezing temperature by the output of the freezing prevention heater 10 and the temperature of the water supply temperature director 11 drops near 0 deg.C again to automatically energize a vaporizing heater 4 in this case. By this method, the temperature of the water supply pipe 1 and the hot water supply pipe 3 is maintained at a value of at least 0 deg.C by the heater 10 mounted thereto respectively and the heat exchanger 2 and its nearby water supply pipe 1 and hot water supply pipe 3 receive heat from the vaporizing heater 4 in order to maintain their temperature at a value of at least 0 deg.C, thereby preventing the water freezing.

Title: Bus using right control system
Inventor: OKANO NAOKI
IPC: G06F13/362
Filed: 1988-07-13
Abstract: PURPOSE:To evade the continuance of processing wait even for a requiring source at low priority, and to effectively process a bus occupying request by using a shift circuit and advancing the priority of the bus occupying request according to the number of times of bus occupying permission. CONSTITUTION:When bus occupying request signals DRQa to DRQc are simultaneously generated from processors 1 to 3, and the priority is given to the request of the processor 1, a request wait condition continues for the processor 3. There, a shift circuit 5 generates a signal DRQc' by four shift clocks and DRQc'' by eight shift clocks by means of a clock generating circuit 11. When the signal DRQc'' is outputted, the priority higher than the signal DRQb is decided by a secondary priority deciding circuit 6, and the request is received after the signal DRQa. Thus, even for the request source at the low priority, when the wait condition continues for a prescribed time, it is made into the condition to have the almost highest priority, the continuance of the processing wait time is avoided, and the bus occupying request can be effectively processed.
