Abstract: PURPOSE:To make possible extremely quickly the elution of the fusible clad glass between multifiber strands by welding the multifiber strands by the fusible clad glass and feeding forcibly an eluate to the spacings between the strands. CONSTITUTION:Many pieces of the fiber strands each consisting of a core 1, a clad 2 and a fusible clad 3 are bundled and heated to form a preform welded with the core-clad strands 4 by the fusible clad glass 3' in the state of having the spacings 5 remaining therebetween. Such preform is further heated to a high temp. and is drawn to form multifibers 6 having the spacings remaining between the strands.

IPC: B24B53/02
Filed: 1981-12-17
Abstract: PURPOSE:To obtain a sizing grinding in high precision by setting a dresser in a dresser elevating device at a sizing position of a required finishing size of a grinded work with fine adjustment for controlling the lowering of the surface of a grindstone in sizing. CONSTITUTION:A work 2 to be grinded is placed on a rotary table 1, and its fixed size is detected by a sizing detector 3. For grinding the work 2 into a required finishing size, at first, a dresser 4 in a dresser elevating device 5 is set at a sizing position of the finishing size.

Title: Magnetic tape device
Inventor: KAJINO JIROU
IPC: H02P5/46
Filed: 1982-11-17
Abstract: PURPOSE:To prevent a tape from getting out of a reel hub in a fast winding mode by reducing the tape feed speed based on the time for obtaining the coincidence of the revolving speed between both reel drive disks and therefore reducing the tape feed speed in the vicinity of the fast winding termination regardless of the tape wind quantity or the diameter of the reel hub. CONSTITUTION:The revolving speed of the reel drive disks 1 and 6 are detected by detection heads 12 and 13 respectively, and the revolving speed signals nS and nT sent from revolving speed detecting circuits 14 and 15 are processed by an arithmetic circuit 16 to compare with a reference signal 17. A control circuit 18 and a driving circuit 10 are controlled to set the difference at 0 between the revolving speed signal and the reference signal. In such a way, a magnetic tape 3 is fed at a fixed speed. The tape roll diameters on the disks 1 and 6 are coincident with each other during winding to operate a revolving speed comparator 20. Then the time tau elapsed since the start of operation is measured by a timer 21. Then a measurement circuit 21 delivers a command to the circuit 18 to reduce the feed speed of the tape 3 in the lapse of time alphatau (0<alpha<1). Thus the circuit 18 controls the circuit 10 to feed the tape 3 at a low speed.

Title: Chatting prevention circuit
Inventor: IWASE HIROSHI
IPC: G06F3/02
Filed: 1992-07-06
Abstract: PURPOSE:To simplify the circuit configuration by storing a change state of a switch and storing a count period relating to the count. CONSTITUTION:When a state of any of plural switches 5 changes, the changing state is stored in a RAM 3. Furthermore, a phase No. is stored for a count period relating to the count of a counter 4. When the counter 4 makes count up to the phase No. stored in the RAM 3, a microcomputer 2 compares the state of the switch stored in the RAM 3 corresponding to the phase No. with the relevant switch state and the state of the switch is discriminated. The counter 4 divides the count into two count periods (phase No.) at a period longer than a minimum time required for preventing switch chattering. Thus, the counter 4 counts time required for chattering prevention for plural switches.

Title: Controlling hot-water filling of automatic bath boiler with hot-water supplier
Inventor: OBAYASHI NAOKI
IPC: F24H1/00
Filed: 1988-08-17
Abstract: PURPOSE:To make it possible to carry out rapidly automatic hot-water supply to a desired water level by measuring the dynamic pressure of a pump and storing it in the control unit of a microcomputer and controlling thereby the hot-water supply for the next time. CONSTITUTION:As soon as hot water supply is started, the pressure measurement by a pressure sensor 10 and the water volume measurement by a water volume sensor 4 are carried out. Values of detection by the pressure sensor 10 is substantially constant until the water level reaches a circulation fixture 14a because there is only the dynamic pressure of the pump while the water level of a bath tub is below the circulation fixture 14a. But when the water level in the bath tub comes above the circulation fixture 14a, the detected value of the pressure sensor 10 rises because the dynamic pressure of the pump and the head pressure due to the water positioned above the circulation fixture are added. The time point at which the detected value of the pressure sensor starts climbing from the substantially constant pressure is detected as a reference time, and the hot-water supply is continued to the bath tub as the output of the pressure sensor is kept to be detected until the time from the reference time to the time when the water level reaches a desired water level set in a controller. When the pressure sensor detects the desired water level, solenoid valves 5 and 6 are closed and at the same time the pump 8 is closed.
