Title: Rotor driving device
Inventor: FUJII YOZO
IPC: H04N1/31
Filed: 1992-09-11
Abstract: PURPOSE:To enhance the quality of image by decreasing speed variation of the rotor of an electrophotographic image output apparatus. CONSTITUTION:A sensitive drum 2 is coupled with the drive shaft 13 on the farther side of a driving gear 11, and an inertial member 8 is installed inside of the drum 2, and a rotary member 18, in which an oil having a high viscosity resistance is encapsulated, is contacted with the drum 2 in its position not related to image formation. Thereby the inertia moment of the driving system is increased and the natural frequency is sunk to prevent resonance of the sensitive drum 2 which is a rotor, and also the damping coefficient ratio zetaof the drum 2 is raised to allow quick damping of momentary speed variation, and the rotating speed is kept constant and speed variation is decreased which should lead to producing of an enhanced image quality.

Title: Grinding tool
Inventor: TOGE NAOKI
IPC: B24D7/14
Filed: 1994-11-02
Abstract: PURPOSE: To realize the uniform wear of a grinding material layer without reducing the biting-in force of the grinding material layer by forming the outer periphery surface portion out of the grinding material layer of a comparatively hard grinding material layer, forming the inner periphery surface portion out of a comparatively soft grinding material layer. CONSTITUTION: A hard layer 2 is formed at the outer periphery portion of a grinding material layer 1, and a soft layer 3 is formed at the inner periphery portion of the grinding material layer 1. Grooves 4 for distributing cooling water that is to be discharged through the center opening 5 of the grinding material layer 1 onto the whole surface of the grinding material layer 1 are formed. The outer periphery surface portion consisting of the hard layer 2 is made so as to occupy the approximate 20-40% of the radius of the grinding material layer 1, and the portion of the inner periphery surface is made so as to occupy the rest of the whole surface area of the grinding material layer 1.  In the case of being smaller than 20%, the effect of forming the hard layer 2 at the outer periphery is small, and in the case of being larger than 40%, the ratio of the hard layer 2 is too high, and sharpness is reduced. As a result, at the rotary speed of 2000-4000rpm, the wear degree of the outer periphery surface portion of the hard layer 2 can be made approximately the same as the wear degree of the inner periphery surface portion.

Title: Heating cooker with weighing scale
Inventor: MIHARA MAKOTO
IPC: F24C7/02
Filed: 1984-12-20
Abstract: PURPOSE:To provide a device which measures weight of food with a high accuracy and also has good cooking performance without a large space in the vertical line to the bottom of a cooker by installing a primary elastic body for weighing light weight food only and secondary one exclusive for heavy weight food. CONSTITUTION:The relation between food weight W and distance (d) between two plates 12a, 12b of a condenser is shown in a figure. In case of weighing light weight food stuff, the primary elastic body 19 is only operated with characteristic as shown by dotted line and in case of weighing beyond heavy weight W1, the primary elastic body is supported by the secondary one and as a result, two elastic bodies 19, 16 are operated simultaneously and weight resolving power becomes poor. The heavier the food stuff weight becomes, the larger the allowable error becomes linearly and therefore, it is sufficient to measure the rough weight in the range beyond weight W1. For poor accuracy, there is no problem on cooking performance and therefore, the same performance is expected with former accuracy.

Title: Antenna reflecting mirror
Inventor: HAYASHI TOSHIHIKO
IPC: H01Q1/28
Filed: 1992-10-08
Abstract: PURPOSE:To prevent the deformation of a reflecting mirror due to the difference of an inside thermal expansion coefficient according to a temperature change on a locus, in an antenna reflecting mirror for space. CONSTITUTION:A compensator 4 which compensates a bending deformation due to the thermal expansion difference or the temperature difference between a shell 1 and a rib 2 constituting a reflecting mirror is provided at the edge side of the rib 2. Then, a bending moment generated between the shell 1 and the rib 2 which causes the warp deformation of the entire antenna reflecting mirror can be canceled. Thus, even when the thermal expansion difference is generated between the shell and the rib, the bending deformation of the antenna reflecting mirror can be prevented.

Filed: 1995-09-25
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of migration resistance and heat resistance, improve workability, and exclude increase of cost, by using thermosetting resin wherein glass balls having substantially the same quality as base material glass are compounded, as thermosetting resin with which glass base material is applied and impregnated. SOLUTION: Spherical glass balls are mixed and compounded in epoxy resin to obtain a solid volume ratio of 40%, and resin composition is formed. The resin composition is subjected to application-impregnation semicure, and continuous prepreg is so manufactured that resin component is 26wt.% and resin flow is 25% in the resin flow test by a JIS method. A printed board is manufactured from the prepreg. When the tests of moldability, solder heat resistance, thermal expansion coefficient, and migration resistance are performed, molding workability, solder heat resistance, and migration resistance are excellent, and thermal expansion coefficient is small, although resin component is low. Thereby response to COB technique is enabled without increasing cost.

Title: Shock display method and shock sensor
Inventor: KAWASHIMA TAKAO
IPC: G01P15/00
Filed: 1996-10-14
Abstract: PROBLEM TO BE SOLVED: To obtain a shock display method in which the level of a shock can be displayed without a need of a power supply by a method wherein a pointer is turned according to the swing of a weight and the pointer is kept at position where it is placed. SOLUTION: An elastic suspension body 17 such as a slender spring, a slender rod or the like, a weight 3 which is connected to its lower end and a rotating plate are installed at a fulcrum 1 which is situated on a scale plate 10. A pointer 16 is formed at the rotating plate, and a protrusion 16a is formed at its lower end. Then, when a shock is applied from the outside, the suspension body 17 comes into contact with the protrusion 16a due to the rotation of the weight 3. As a result, the pointer 16 is turned to the left direction, and the suspension body 17 is returned immediately to its original vertical state. However, the rotating plate which comprises the pointer 16 is not returned to its original position due to friction with the fulcrum 1. Consequently, only the pointer 16 is set to a pointer-set state in a position in which the input level of the shock is displayed.  Thereby, the level of the shock can be displayed without a need of a power supply.

Title: Loading controller for garbage collecting vehicle
Inventor: SHIMAZU YOSHITAKA
IPC: B65F3/28
Filed: 1988-10-27
Abstract: PURPOSE:To improve efficiency by continuing a pressed state for a fixed time and controlling an exhaust cylinder without steps for a given time by pressure acting on a garbage loader driving hydraulic actuator. CONSTITUTION:A second expansion cylinder 15 is compressed by the reaction of garbage action on a pressing plate 12 in the pressing stroke of the garbage and its charging pressure is increased. When this pressure reaches a constant pressure, that is, the reaction of the garbage exceeds the constant pressure, a pressure switch PS operates to operate a timer. According to this timer operation, an electromagnetic selector valve V is operated by a solenoid SOLg until a timer time passes. Thus, the hydraulic pressure of the back pressure side of an exhaust piston is exhausted to an oil reservoir T, thereby advancing an exhaust plate 17 and increasing garbage accommodating space, and therefore, the garbage is pressed with high density until the next operation of the pressure switch.
