Title: Method and apparatus for measuring impregnating depth of impregnating material
Inventor: MACHI YOSHIO
IPC: G01N27/02
Filed: 1987-08-28
Abstract: PURPOSE:To make it possible to measure the impregnating depth of an impregnating material without destruction of a structure, by bringing a pair of electrodes into contact with the surfaces of an impregnated element, and applying a high frequency current. CONSTITUTION:A pair of electrodes 10 and 10' are brought into contact with the surfaces of an impregnated element 9. An inductor 6 is connected to one electrode 10. A high frequency current is applied across the pair of the electrodes 10 and 10' through the inductor 6. An RLC series circuit is formed with the inductance L of the inductor 6, the electrostatic capacitance C formed between the electrodes 10 and 10' and the resistance R of the impregnated element, which is impregnated with the impregnating material between the electrodes 10 and 10'. When the RLC series circuit is resonated, the impedance of the circuit is made equal to the resistance R of the impregnated element 9. The output signal from the RLC series circuit at this time is detected 11, and the value of the DC component is measured with an ammeter 13. Thus, the change in resistance R of the impregnated element 9 is obtained, and the impregnating depth of the impregnating material is measured.

Abstract: PURPOSE:To prevent a vehicle speed from being increased in traveling of a vehicle on a down slope by driving a waste brake of a diesel engine with use of a vehicle speed deviation or a driving duty ratio specified on the basis of said deviation and an amount of fuel injection when an actual vehicle speed is more increased than a target vehicle speed. CONSTITUTION:Judged, on the basis of an output from a group of switches 12 for instructing constant-speed traveling, a fact that constant speed traveling control is executed in a control unit 13, an amount of fuel injection is determined in response to a deviation between an actual vehicle speed detected by a vehicle speed sensor 10 and a target vehicle speed. Then, when the actual vehicle speed is greater than the target vehicle speed, a secondary map is retrieved on the basis of said amount of fuel injection and the deviation between the vehicle speeds described before for determining a duty ratio of a solenoid valve 7. A pulse signal of this duty ratio is supplied to the solenoid valve 7 via a drive circuit 23 whereby a vacuum tank 8 is guided into a vacuum cylinder 5 in an on-state of the same valve 7 to drive a waste throttle valve 4 in a direction of closing it for assuring claming by a waste valve.

Title: Ultra high density ink ribbon
Inventor: KITAMURA ATSUSHI
IPC: B41J31/02
Filed: 1989-08-22
Abstract: PURPOSE:To improve the definition of printing and at the same time solve the problem of density at a lead mark and edge end parts by specifying the density and thickness of warps and wefts which constitute the texture of an ink ribbon. CONSTITUTION:Warps and wefts which constitute the texture of an ink ribbon are made of multifilament yarn, and when it is taken that the density of warp is to be A (number/inch), and the density of weft is to be B (number/inch), the thickness of warp is to be x(d), and the thickness of weft is to be y(d), all the following equations are satisfied. For the material, nylon (nylon 66 or nylon 6) is suitable, and polyester can be used also. Thus, since the woven texture has an ultra high density, the definition of printing becomes better even under a high speed or ultra high speed printing, or high dot printing. Also, the difference in density between lead marks and edge end parts and the base part is drastically reduced or eliminated.

Abstract: PURPOSE:To exactly control the movement of a pick-up by arranging the pick-up to a prescribed position with a moving means in a condition that the pick-up is supported with a spring member. CONSTITUTION:When setting is executed so that an arrow (c) can be defined as the direction of gravity, since a pick-up 15 is moved in the arrow (c) direction by dead weight, a leaf spring 20 is bent and elastic force is generated to return to a natural condition. The movement of the pick-up 15 in the arrow (c) direction is stopped in a condition that the dead weight of the pick-up 15 and the elastic force of the plate spring 20 are balanced. In such a condition, when an auxiliary motor 25 is rotated and a slide member 21 is moved in arrow (c) and (d) directions, the pick-up 15 is also moved in the same direction. Namely, while the balanced condition is kept for the dead weight of the pick-up 15 and the elastic force of the plate spring 20, the moving force of the slide member 21 is transmitted through the leaf spring 20 to the pick-up 15. Thus, the movement of the pick-up can be exactly controlled.

Filed: 1982-12-13
Abstract: PURPOSE:To permit easy insertion of the other involute serration internal gear having a normal tooth thickness by making the part of flat dies for rolling which rolls the open side end of a blank material thickener than the normal tooth thickness part. CONSTITUTION:A cylindrical blank material 7 is grasped by the teeth 5, 6 of flat dies 3, 4 and the dies 3, 4 are moved relatively reverse (in arrow direction) in parallel with each other, whereby an involute serration shaft is cold rolled. The part 9 (the part between tooth lengths a-b-c) of the teeth 5, 6 for rolling the open side end 8 of the shaft 7 to be worked is made thicker in tooth thickness than such a normal thooth thickness part (between tooth lengths c-d) where the tooth profile of the shaft 7 has the normal tooth thickness. If the shaft is rolled with such flat dies, the tooth thickness of the tooth profile in the end part 8 rolled by the part 9, that is, between A-B-C is thinner than the part 11 between C-D where the tooth thickness is normal, and said part is continuous with the part 11. It is therefore possible to insert easily the other involute serration internal gear having the normal thickness to the end part of the shaft 7.
