Title: Motor control apparatus for battery powdered vehicle
Inventor: MURATA HIROSHI
IPC: B60L15/28
Filed: 1998-06-26
Abstract: PROBLEM TO BE SOLVED: To set the capacitance of a snubber capacitor used in common for a two semiconductor switching elements to a value which is identical to the capacitance of the snubber capacitor having a larger capacitance, when an independent snubber circuit is provided to each semiconductor switching element. SOLUTION: A microcomputer 44 issues a command to a drive circuit 13, by setting a duty ratio for chopper drive a transistor 15 for running and a transistor 30 for working. Moreover, the frequency of each chopper drive signal is selected from the reference frequency and the frequency, which is a multiple of 2 of the reference frequency based on the predetermined condition. The drive circuit 13 generates each chopper drive signal with the commanded duty ratio and frequency and then outputs this signal for providing inverted on and off modes in a timing such that the starting points in the switching period of both chopper drive signals match. The microcomputer 44 does not set the duty ratio equal to 1/(multiple of 2) to a running chopper drive signal VC1 output from the on mode.

Title: Controller for stepping motor
Inventor: TOMITA MIKIO
IPC: H02P8/12
Filed: 1984-08-30
Abstract: PURPOSE:To facilitate the manual operation at holding time by supplying an adequate power to the winding of a stepping motor from a holding power source separately from a driving power source at the holding time. CONSTITUTION:When a hold signal is applied to a terminal 11, a gate 10 interrupts a control signal output from a comparator 6. Thus, a transistor 8 is turned OFF to interrupt the power of a drive power source 1. Accordingly, only power is supplied from a holding power source 12 to a winding 2. Since the current flowed to the winding 2 at holding time is decided by the resistance value of a resistor 13, the resistance value of the resistor 13 is determined so that the winding current becomes optimum by considering the operability in the manual operation at the holding time and the stability of the rotor position at the holding time.

Title: Concentrated answer system for telephone
Inventor: FUJII AKIRA
IPC: H04M3/60
Filed: 1985-08-21
Abstract: PURPOSE:To use a signal which is usually used for a private line as it is and to display the different type of call on the attendant board of a master station, by deciding the type of call to be transferred to the master station from a slave station as 'incoming', 'recall' and 'holding' according to the type of signal. CONSTITUTION:When a call is given from a trunk line, a both-way trunk BWT catches a slave station additional trunk SRLT. The trunk SRLT confirms the incoming display and sends the incoming display to a master station answer trunk CAST. In this case, the dial pulse is sent to the master station from the slave station since the call is given from the trunk line. When the attendant board of the master station is called again by a slave station subscriber EXTB, the SRLT is caught with the operation of the EXTB to obtain the information on the recall. Then the MF signal is sent to the CAST from the SRLT and therefore the CAST discriminates the recall and turns on a recall lamp on the attendant board of the master station. When the holding of the BWT is desired, the digital signal is sent to the SRLT from the CAST. Thus the SRLT discriminates the digital signal and holds the BWT.

Filed: 1989-07-14
Abstract: PURPOSE:To obtain stable oscillation action with a low-loss bleeder by outputting voltage through a resistor at the time of switching ON and making it a part of an auxiliary power source. CONSTITUTION:A switching transistor 10 performs ON/OFF operation in order to make output voltage C constant.
