Title: Manufacture of composite tube
Inventor: OWADA TAKEO
IPC: B29C41/04
Filed: 1989-12-15
Abstract: PURPOSE:To enhance durability of a tube by applying or pouring a composition containing heat-curing resin and an aggregate in the inner side of the tube while the tube is rotated and then curing it. CONSTITUTION:A protection layer on the inner side of a tube is formed by applying or pouring in a composition containing heat-curing resin and an aggregate while the tube is rotated, and then curing. The rotation at that time is carried out by placing the tube on a rotating table set along the axial direction of the tube by a motor and rotating said rotating table. Curing is carried out by using a curing agent or the combination of the curing agent and a cure accelerating agent under the normal temperature or heated state. Curing is carried out by rotating the tube. The protection layer thus formed is provided with superior bonding properties with the tube, resistance to water, resistance to wear and resistance to chemicals, and durability of a composite tube can be enhanced.

Title: Power controller for copying machine
Inventor: ARAKI KAZUO
IPC: G05F1/66
Filed: 1990-11-28
Abstract: PURPOSE:To hold the temperature of a fixing unit at a predetemined value or higher, and to prevent interruption of continuous copying by detecting current flowing except the fixing unit, and turning ON a fixing main heater when a detected current is a predetermined value or less. CONSTITUTION:An output (a) of a current detector 7 is rectified by a current detector 6, compared with a predetermined value, and digitized. A controller 12 judges, when inputting a digital signal, whether its value is 'H' or 'L'. When the value is 'L', i.e., when a sensed current becomes a predetermined value or less, a fixing main heater 1 is simultaneously turned OFF, and a fixing subheater 2 is turned ON by a zero-cross signal directly thereafter. On the other hand, when the value is 'H', i.e., when a sensed current becomes larger than a predetermined value, the subheater 2 is simultaneously turned OFF, and a fixing main heater 1 is turned ON by a zero-cross signal directly thereafter.

Abstract: PROBLEM TO BE SOLVED: To provide a discharge-lamp lighting device capable of surely producing a start voltage. SOLUTION: When a transistor Q1 is turned on by a control circuit 5, current flows through a capacitor C2, and through a first inductor L1, a second inductor L2, and a primary winding Tr1a of an inverter transformer Tr1, whereby voltage is induced in a secondary winding Tr1b and a detection winding Tr1c of the inverter transformer Tr1, respectively. A fluorescent lamp FL is high-frequency lit based on the voltage induced in the secondary winding Tr1b by parallel resonance of the capacitor C2, the first inductor L1, the second inductor L2, and the primary winding Tr1a of the inverter transformer Tr1.  The voltage induced in the secondary winding Tr1b is produced in a resistor R2 by way of the detection winding Tr1c, this voltage is detected by a detection circuit 7, the voltage of the resistor R2 is kept constant by the control circuit 5 if an inductance circuit 4 for resonance, the capacitor C2 for resonance, a capacitor C3, and other components have dispersion in their values, whereby voltage applied to the fluorescent lamp FL is kept constant, and thus its starting and lighting are made certain.
