Title: Production of preform for optical fiber and apparatus therefor
Inventor: SUDO SHOICHI
IPC: C03B37/018
Filed: 1986-03-20
Abstract: PURPOSE:To stably and readily produce a preform for optical fibers, by depositing fine glass particles synthesized in a flame in separate reaction vessels and respectively forming a core porous glass body of a small diameter and thick clad porous glass body. CONSTITUTION:Fine glass particles synthesized in a core flame stream 31 of a core torch 24 are adhered and deposited in the axial direction of a starting material 32 to be pulled up in the axial direction while rotated to form a core porous glass body 29 of a small diameter. A thick clad porous glass body layer 34 is similarly formed on the side of the above-mentioned glass body 29. The resultant porous glass body is then heated and sintered at a high temperature and transparentized to give a preform for optical fibers. In the above-mentioned method, the core porous glass body 29 and clad porous glass body layer 34 are respectively formed in the first and second reaction vessels 21 and 22 individually separated by a separating vessel 23. Thereby the core porous glass body 29 of the small diameter is stably formed without any influence of a clad flame stream 33 to afford the aimed preform having a given diameter ratio of the clad layer to the core.

Filed: 1990-03-12
Abstract: PURPOSE: To reduce power consumption in a rectifier diode by providing an AC power output circuit and an inductive filter circuit and a rectifier circuit responding to the AC power, and reducing a current surge or a spike generated by a diode turn-off recovery in the inductive filter circuit. CONSTITUTION: The output of a sine wave electric power source 11 is supplied to a balanced filter circuit 30, and the balanced filter circuit 30 gives its output to a rectifier and filter module 21. The rectifier and filter module 21 performs full-wave rectification, so as to generate a DC output voltage. At that time, in the filter circuit 30, an inductor functions so that a current spike or a surge due to the reverse conduction of a reverse biased diode of the rectifier and the filter module 21 is reduced. Namely, a current load given to the AC power source by the recovery of a diode is reduced.

Abstract: PURPOSE:To facilitate the recognition of a defective sensor by connecting the power source output terminal to check the fire sensor of a previous stage with the power source input terminal to check the fire sensor of a next stage successively from the fire sensor of a first stage to the fire sensor of a last stage and connecting the power source input terminal to check the first stage with the power source to check. CONSTITUTION:When a thyrister Q4 is turned on, an interval between a power source input terminal to check Ia and a power source output terminal to check Ib is short-cut through the thyrister Q4 and the power source to check is supplied to the fire sensor of the next stage. On the other hand, a timer circuit 10 charges a capacitor C2 from the supply of the power source to check and when the charging voltage exceeds a specific voltage, a transistor Q7 is turned on. A trigger signal is made to give to the thyrister Q4, and even when a control output is not generated from a comparing part 5 by a trouble in case of the breaking of a negative characteristic thermistor 8a or the like, the thyrister Q4 is forcibly turned on after an elapse of 30sec. Thus, the action check of the fire sensor from the first stage to the last stage can be successively executed.

Title: Agitator for washing machine
Inventor: IMAI TORU
IPC: D06F17/10
Filed: 1988-03-15
Abstract: PURPOSE:To prevent the damage of the wash without decreasing detergency and to decrease the torque required for driving by forming projecting line parts increasingly gently toward the upper outside circumferential edge of a base plate and forming the base plate to the shape which is largest in the intermediate section of the projecting line parts. CONSTITUTION:The slopes 11b ranging from the ridge line parts 11a of the projecting line parts 11 to the base plate 8 are so formed that said slopes incline largely in the section near the outside circumference close to a boss part and incline relatively gently in the intermediate section. The friction force between the wash and the projecting line part is thereby uniformized and the damage of the wash is suppressed. The base plate 8 constitutes a horizontal plane 8a from the boss part 9 to approximately the intermediate section of the projecting line parts 11 and constitutes, therefrom, the slope 8b which ranges up to the upper outside circumferential edge 10 of the base plate 8. The base plate 8 is, therefore, so recessed and formed that the height therefrom up to the ridge line parts 11a of the projecting line parts 11 is largest in the intermediate section of the projecting line parts 11. The decrease of the detergency in this part is thus prevented.

Title: Digital data holding circuit
Inventor: SHIBAZAKI NOBUO
IPC: H03K3/037
Filed: 1983-04-11
Abstract: PURPOSE:To reduce the number of MOSFETs by providing a passive element which connects the output of a holding circuit to a reset level according to a reset signal to a digital data holding circuit which holds data by a positive feedback loop. CONSTITUTION:When a clock signal phi is inputted while an input IN is at a level H, the output OUT of an inverter I4 rises up to a level H and is fed back positively to the input (a) of the inverter I4 by an inverter I3 to hold the output OUT at the level H. Similarly, when the clock signal phi is inputted while the input IN is at a level L, the output OUT is held at the level L. When a reset signal is inputted, an MOSFETQ5 holds the output OUT at the level L forcibly, so the output OUT is reset to the level L. For this purpose, the passive element Q5 which connects the output OUT to the reset level by the reset signal R is provided, so an NOR circuit which is used conventionally is substituted with the inverter I4 and passive element Q5. Then, the number of MOSFETs is decreased by one.
