Title: Wiper controller for vehicle
Inventor: UKAI TAKASHI
IPC: B60S1/08
Filed: 1996-02-15
Abstract: PROBLEM TO BE SOLVED: To provide a stop/move function which automatically switches a wiper mode of a wiper, when a vehicle enters a stop state from a running state, through inexpensive constitution. SOLUTION: When a wiper switch 9 is on a low speed wiping mode position LO, since a transistor 11 is continuously turned on so as to electrify an exciting coil 10b, an electrifying passage for a wiper motor 5 is formed through contacts (c to a) of a relay switch 10a. When the vehicle is in a running state, since the charge of a condenser 13 is discharged by a transistor 14, which was turned on, a transistor 12 is put off, while the transistor 11 is held in an 'on' state. When the vehicle stops, since the transistor 14 is turned off, the condenser 13 is charged through contacts (c to a) of a scheduledposition-stop-switch 6 and while the wiper is out of the 'wait' position. Thus, the transistor 12 is turrted on, while the transistor 11 is forcibly turned off.  This 'off' state is maintained until a prescribed time has elapsed after the wiper returned to the 'wait' position to start the discharge of the condenser 13.

Title: Heat fixing device
Inventor: SASAKI YOSHITAKA
IPC: H05B3/00
Filed: 1983-02-24
Abstract: PURPOSE:To make uniform a heating temperature extending over the overall length of a heating roll and to prevent thermal radiation by constituting the roll body of the heating roll of a hollow core having a large thermal conductivity and a shaft part of a member having a small thermal conductivity. CONSTITUTION:The heating roll 1 and a pressure roll 2 which are press-contacted to each other are rotated by a driving mechanism, and when a voltage is impressed to a feed brush from a commercial AC power source, a current flows to a resistance heating element layer 9 through annular electrodes 10, 10a, to heat. In this case, a hollow core 5 has a large thermal conductivity, therefore, a heating temperature is made uniform quickly extending over the overall length. Shaft parts 6, 6a consist of a member having a small thermal conductivity to prevent thermal radiation from both end parts of the heating roll 1. Accordingly, when a supporting body holding a toner is made to pass through between the heating roll 1 and the pressure roll 2, the fixed picture of a good quality having no fixing failure is obtained.
