Title: Electrifying member and electrifying device
Inventor: ISHIHARA TOMOJI
IPC: G03G15/02
Filed: 1996-12-05
Abstract: PROBLEM TO BE SOLVED: To uniformly electrify the surface of a body to be electrified and to supply an excellent image over a long period at a low cost by setting the difference between the maximum and minimum heights in a surface where a tube member is in contact with a supporting body to a specific value or below. SOLUTION: It is constituted so that at least the supporting body and the tube member covering it are provided. Then, the difference between the maximum and minimum heights in the surface where the tube member is in contact with the supporting body is made <=50μm, to obtain smoothness. Since a contact area is made actually larger and close contact can be improved, fitting force can be reduced. When this fitting force can be reduced, stress, distortion, etc., applied on the tube member can be reduced, so that an electrifying member and device whose characteristics are stable over the long period can be obtained. When the roughness of the inside surface of the tube member is greater than 50μm, the close contactness is insufficient, so that there is a possibility that electrification evenness can not be obtained.

The output of the dividing section 1 indicates the W1/W2 value and the output of the dividing section 2 indicates the W3/W2 value. If the above-mentioned output values are analog quantities, the values are quantized and converted to digital quantities in the ensuing A/D sections 1, 2 and are made respectively into quantized data. The above-mentioned W1/W2 value and W2/W3 value are the values corresponding to the chromaticity chart coordinates of the input image signals. Then, the outputs, W1/W2, W3/W2 values of the dividing sections 1, 2 indicate the values corresponding to the chromaticity coordinates.

Title: Heater for cooking
Inventor: YAMAMOTO FUMIO
IPC: F24C3/12
Filed: 1989-12-26
Abstract: PURPOSE:To simplify the handling method and secure a highly reliable overheating- preventive function by a method wherein, when overheating-preventive control has been manually suspended and temporary high-temperature heating has been effected, an overheating-preventive means is automatically reset to be ready for effecting its overheating-preventive control. CONSTITUTION:When, after the start of cooking, the temperature (tx) of the bottom of a pan, detected by a thermistor 13, has risen to a high point exceeding a set point (ts), a buzzer 15 operates to give a signal, and unless a command to suspend the setting is manually given, the combustion at a burner 1 is automatically extinguished after an elapse of a set standby time T2. If, in acting against the operation of the buzzer 15, the user considers heating at high temperatures above the set point (ts) necessary and manually gives an command to suspend the setting before the set standby time T2 terminates, the buzzer 15 stops signaling and the combustion keeping up the high temperature heating is maintained. When the combustion is thus continued and if, after continuation of the combustion within a set time T1 to reset, the detected temperature (tx) is above the set point (ts) and hence the condition requires an automatic extinguishing means 5A to execute the automatic extinguishment, the buzzer 15 is actuated again and, unless a command to suspend the execution is manually given, the extinguishment of the combustion is executed.
