Title: Image forming device and method
Inventor: YOKOGAWA NOBUHITO
IPC: G03G21/00
Filed: 1999-07-23
Abstract: PROBLEM TO BE SOLVED: To obtain appropriate developing ability by using an image carrier whose friction coefficient is made low so that its life can be prolonged by setting applying time when toner is stuck to an image carrier longer than applying time when it is peeled therefrom. SOLUTION: AC voltage on which DC voltage is superposed is used as developing bias voltage. The reproducibility of a solid image is comparatively excellent whatever a developing condition is set when a photoreceptor 11 is coated with lubricant so as to make the friction coefficient low, but it is remarkably deteriorated at a halftone image part and a dot image part. The reproducibility of the dot image and the halftone image is improved by setting the time to generate an electric field in a direction where the toner is supplied and stuck to the photoreceptor 11 from a developing sleeve 13a longer than the time to generate the electric field in the direction where the toner is peeled from the photoreceptor 11 and restored to the sleeve 13a in one cycle of an AC component.

Abstract: PURPOSE:To decrease the deterioration of a gradient gain ratio and the deterioration of relative linearity of a gradient magnetic field by forming a current path so that magnitude of a circular arc direction component of current density is proportional to (cos theta)<n>, when an angle looked at from the center axis of a cylinder is set as theta, based on a symmetry axis of the current path as a reference, and also, 0<n<1. CONSTITUTION:A current path 3 of a printed board 2 for forming a curved shape coil 1 is formed so as to satisfy the following conditions. (1) The current path 3 is a spiral shape being symmetrical to a symmetry axis P. (2) The printed board 2 is curved to a 1/2 shape of a cylinder in which width Lc of the printed board 2 is half peripheral length, and when an angle looking at the curved shape coil 1 from the center axis of a cylinder is set as theta, based on a symmetry axis P of the current path as a reference, and also, 0<n<1, magnitude of a circular are direction component of current density is proportional to (cos theta)<n>. Therefore, comparing with a conventional curved shape coil, the circular arc direction component of current density becomes large as theta approaches + or -pi/2. Also, by an increase in this current density, a deterioration portion of a characteristic is compensated.

Title: Safety device for water heater
Inventor: EGAMI TOYOHIKO
IPC: F24H1/10
Filed: 1986-09-05
Abstract: PURPOSE:To improve the safety in regard to the oxygen defficiency and failure to shut off a hot water tap by forcing a suspension of burning and interrupting the counting action of a timer in case where an abnormal condition is detected by a water flow sensor. CONSTITUTION:Detection signals from a flow rate sensor 3, a thermistor 4 and a rotation sensor 9 are inputted to a controller 10. When a water flow is detected upon opening a hot water tap 5, a timer is set, and, if there is no abnormality from the sensors, a gas valve 7 is opened and a fan 8 is operated to start the burning at a gas burner 6. If the timer counts up, the gas valve is forcibly shut off and the 8 stopped to ensure the safety. If an abnormality is detected by any sensors, the burning is suspended to assume a burning holding mode. If the normal condition is regained under such a condition, the timer is not reset but resumes the counting action from the interrupted point. As a result, the burning time does not exceed the time period set by the timer even if an abnormality should occur.

Abstract: PURPOSE:To prevent a frequency changeover of a digital data line and to improve the stability and reliability of a line transmission condition by providing a means or the like generating plural monitor signals to a transmission destination and providing a means or the like sending a reply signal to a reception section. CONSTITUTION:A reception section 20a sends a reply signal A to a transmission section 10a when a 1st monitor signal W1 generated from the transmission section 10a at a prescribed interval N and a minor error message is received through the production of a slight minor error on a digital line 1. The section 10a sends a 2nd monitor signal W2 in response to the signal A, the section 20a is received normally and the line 1 is not changed over. However, when an important burst error message is received and the signal A is sent to the section 10a, since the burst error is generated for a time continuously, the section 10a cannot receive the signal A. Thus, the section 10a cannot generate a signal W2 and the section 20a cannot receive the signal W2, then the line 1 is changed over, the stability of the line transmission condition is improved and the reliability is enhanced.
