Title: Pulse generator and dust collecting device
Inventor: NAKAJIMA SUSUMU
IPC: B03C3/68
Filed: 1993-01-08
Abstract: PURPOSE:To easily change the pulse width of a pulse voltage to be supplied to a load by controlling a period in which energy is applied to the load by means of a magetic amplifier. CONSTITUTION:The period in which energy is applied to the load is controlled by the magnetic amplifier connected between the load side one terminal of a saturatable reactor 5 and an energy accumulating capcitor 3. Namely a period taus2 from the change of a pulse current i4 flowing into a thyristor 4 to zero up to the start of inflow of a pulse current into a magnetic amplifier constituted of a diode 18 and a saturatable reator 19 can be controlled by changing a reset current 121 flowing into the control winding 21 of the reactor 19 so that the period taus2 is extended in accordance with the increment of the value of the reset current I21. Thereby the pulse width (tau1+taus2+tau2) of pulse voltage superposed to a dust collecting electrode 12 can easily be changed.

Title: Order calling system
Inventor: TAKAHASHI AKIHIRO
IPC: H04M9/00
Filed: 1990-01-09
Abstract: PURPOSE:To eliminate the need for a complicate function such as a station selecting function without calling another station unnecessarily nor outputting an order voice by assigning channels to respective stations and enabling each of the stations to receive its channel in its reception state. CONSTITUTION:For example, when a station 201 originates to make an order communication with a station 202, the service engineer of the station 201 adjusts a selection switch 211 to a channel B which is the channel of a target opposite station. The order signal from the station 201 is inserted into the B channel part of a digital signal by a branching/inserting circuit 221 and sent out and the selection switch 212 of the station 202 selects the channel B in the reception wait state previously, so the order signal is regenerated in the station 202. At this time, selection switches of the stations except the station 202 select the channels of their station channels, so the order signal from the station 201 is never regenerated. Consequently, the target opposite station can securely be selected with the simple circuit constitution.

IPC: G11C11/417
Filed: 1985-01-10
Abstract: PURPOSE:To speed up bit line discharge at the time of reading operation and enable high speed reading by making discharge operation continuously after precharge operation. CONSTITUTION:When an address changes and reading operation is started, change point of the address is detected in a pulse generating circuit 2, and precharge is made to bit lines 5, 6 by a precharge circuit 3. After a precharge signal becomes 'H' and precharge is completed, a discharge signal becomes 'H' and discharge of bit lines 5, 6 is made by a discharge circuit 4. After completion of discharge, a word line becomes 'H'. When a memory cell 7 is selected, potential of bit lines 5, 6 changes at once reflecting the content of the memory cell 7, and data are outputted to a data outputting line 10. Thus, potential of the bit line and threshold value VTH are made nearly equal by precharge and discharge of the bit line. Thereby, discharge of the bit line by the memory cell becomes unnecessary, and high speed reading becomes possible.
