Title: Voltage controlled oscillating circuit
Inventor: NAKAGAWARA TOMOMASA
IPC: H03B5/12
Filed: 1989-10-26
Abstract: PURPOSE:To obtain the variable range of sufficient oscillating frequencies by means of a small current by changing the oscillating frequencies with changing the bias current of an oscillating transistor(TR), and controlling the voltage between collector bases of the oscillating TR. CONSTITUTION:A control TR forming a differential pair with a control TR3 is made into a TR40 in a double collector shape, respective collectors are connected to the bases of TRs 1 and 2, and resistances 14 and 15 are inserted to feedback paths 11 and 12. In such a constitution, when the voltage value of a controlled voltage source 8 is increase, for example, in order to increase the oscillating frequencies, the collector current of the TR40 is increased, and the voltage value between the collector bases of the both oscillating TRs 1 and 2 is increased. Thus, the base voltage between the respective TRs 1 and 2 is increased, and the capacity value of the collector bases is decreased. The oscillating frequencies are determined by a resonance circuit consisting of a capacitor 9 and an inductor 10, in addition the contribution of the capacity between the collector bases is large, and by decreasing the capacity value, the oscillating frequencies is increased.

Title: Drive control device for stepping motor
Inventor: HAITANI MUNEHISA
IPC: H02P8/00
Filed: 1988-11-04
Abstract: PURPOSE:To obtain a driving control device taking short settling time by controlling the driving current supplying to the exciting phase in accordance with the detected output corresponding to the counter electromotive voltage caused to the non-exciting phase in the direction where the oscillation in the stop position after the seek of a stepping motor is converged. CONSTITUTION:By the use of a winding of non-exciting phase the counter electromotive voltage caused to the winding is detected without providing an exclusive generating winding. The counter electromotive voltage thus detected is then changed over to input for control and the exciting current supplying to the exciting phase yet to be excited is fed back in the direction where the oscillation in the stop position is converged, i.e., in the direction of a counter. The oscillation of a rotor of a stepping motor in its stop position can thereby be converged in a shorter time than before.

Title: Method and device for melting ash
Inventor: YASUOKA SHO
IPC: B01D47/02
Filed: 1995-10-26
Abstract: PROBLEM TO BE SOLVED: To prevent damage to a body of furnace by discharging molten ashes together with molten glass out of a molten ash and glass outlet port. SOLUTION: Glass is supplied into a furnace 10 from a glass feed part 2. The glass is melted by means of a burners 4 and stored on the bottom of the furnace so that a molten glass furnace floor 5 is formed. If ashes are introduced from an ash feed part under such conditions, the ashes fall down on the floor 5 and heated by molter glass and the burners 4 and melted. Since the floor 5 is formed from glass having low erosiveness and ashes are fed on the floor to melt the ashes on the molten glass, the molten ashes are prevented from coming in contact with the body of the furnace. The molten ashes are discharged from a molten ash and glass outlet port by causing the ashes to overflow or the ashes are wound up by means of a molten ash and glass winding device with a molten ash and glass outlet port and delivered. The discharged ashes and glass are cooled with water and formed into slag.
