Title: Form measuring device
Inventor: KATOU MASAHIKO
IPC: G01B7/00
Filed: 1981-08-14
Abstract: PURPOSE:To keep the pressure of measurement at a small and constant level and to realize the quick measurement, by attaching a quartz oscillator to the tip of a probe and controlling the pressure of measurement for the probe in accordance with the fluctuation of the phase and frequency of the quartz oscillator which is due to the change of the pressure of measurement of the probe. CONSTITUTION:When a probe 31 has a relative shift and contact with the surface to be measured, a diaphragm-shaped spring 50 has a displacement with the contact pressure of the probe 31. Thus the size of a gap 49 changes. Then an electric field is applied to the area between an electrode 43 and a probe 35, and accordingly the electric capacitance varies to an electrode formed by the electrode 43 and the probe 35. Then the phase difference and frequency are changed for a quartz oscillator consisting of a quartz plate 47, the electrode 43 and the probe 35. This change is detcted, and a current is flowed to a coil 33 in accordance with said change in order to keep the gap 49 at a certain size. As a result, the pressure of measurement is kept at a small and constant level to ensure the quick measurement.

Abstract: PURPOSE:To reduce the warm-up time and to lower an overshootly input electric  power, by generating a ready signal before the temperature in the fixing equipment  reaches the controlling temperature, and to set a copying machine to a condition  which is able to copy. CONSTITUTION:A temperature detecting element 5, such as thermister, etc., installed near the surface of a heating roll 1, constructs a bridge circuit with an internal resistance RT and a plural number of resistances R1, R2, R3, and R4, and an  electric potential VA between the temperature detecting element 5 and the resistance  R1 and another electric potential VC between the resistances R2 and R3 are input  into a comparator for detecting ready temprature 6. Also, the above mentioned electric potential VA and an electric potential VB between the resistances R3 and R4 are  input into another comparator for detecting controlling temperature 7. By such a  construction, overshoots caused because no correct temperature is detected since the temperarure detector and its periphery are cold just after the electric power is input, is reduced sharply, thus the warm-up time is reduced and the electric power is economized.

Abstract: PURPOSE:To keep a diode, when wetted, from absorbing moisture and thus prevent the corrosion and deterioration of the device by a method wherein the diode is coated doubly with a resin sheet and a powdery resin and the gap between the diode and the recessed part of a cooling fin is filled with a resin. CONSTITUTION:A diode 12 is fixed to a recessed part 16 of a cooling fin 15; the recessed part 16 is covered with a resin sheet 25. When resins 26 applied to both sides of a netlike base material 28 are heated, the sheet 25 is melted mainly at the base material 28; the base material 28 presses the upper part; and the resins 26 do not flow out and cover the diode 12 which is covered with a silicone rubber 11. At the same time, the gap between the diode 12 and the recessed part 16 is filled and bonded. At this time, even when a net is heated, the base material 28 is not deformed and covers the surface of the diode 12 surely without protruding to the outside. After that, the fin 15 including the resins 26 and the base material 28 is covered surely with a powdery resin 20 whose bonding property is good. Thereby, even when the recessed part 16 is wetted, moisture does not infiltrate into the diode 12 which is covered with the resins 26 and the resin 20 which is melted and bonded; and it is possible to prevent the corrosion and the deterioration by the moisture and to prevent a short circuit from being caused.

Title: Friction drive gear for rotary body
Inventor: IDA KATSU
IPC: F16H13/14
Filed: 1982-07-22
Abstract: PURPOSE:To impart a predetermined initial contact pressure to a friction wheel and transmit a predetermined torque, by providing an energizing means for energizing the friction wheel to rotate in the direction of a contact surface with an eccentric fulcrum as a center. CONSTITUTION:An arm 39 of a front side plate 34 for the motor is energized downward by a tension coil spring 67. Therefore, a motor pulley 8 is energized in the direction of an arrow (g) with a fulcrum 61 as a center, and is pressed against a rubber member 70 of a capstan pulley 9. When the motor pulley 8 is rotated in the direction of an arrow (a) by the initial contact pressure, it tends to rotate the capstan pulley 9 in the direction of an arrow (b) by a frictional force P corresponding to the initial contact pressure, so that a reaction force P corresponding to the frictional force P is exerted on the contact surface of the pulley 8 in a direction of an arrow (i) opposite to the direction of the arrow (b), and the pulley 8 is rotated with a moment Pn in the direction of the arrow (g) with the fulcrum 61 as a center. By the rotating torque, the pulley 8 is pressed against the pulley 9 with a contact pressure larger than the initial contact pressure, so that the frictional force P is further inceased. When the frictional force sequentially increased through these processes reaches a load on the capstan pulley 9, the pulley 9 starts to be rotated, resulting in a normal operating condition.
