Title: Manufacture of tough and hard bar steel
Inventor: OOWADA NORIYOSHI
IPC: B21B1/16
Filed: 1989-03-31
Abstract: PURPOSE:To directly manufacture the tough and hard non heat-treated bar steel in an off-line state by subjecting a steel contg. specified wt.% of C, Si, Mn and V to heating and rolling at a specified temp., thereafter rapidly cooling the surface to the Ms point or below and recuperating the surface temp. to the specified one by internal holding heat. CONSTITUTION:By weight, 0.20 to 0.50% C, 0.10 to 1.00% Si, 0.80 to 1.80% Mn and 0.05 to 0.30% V are incorporated into a steel. The billet is heated to 900 to 1100 deg.C, is rolled and is subjected to finish rolling at 750 to 1050 deg.C. After that, the surface of the steel is rapidly cooled to the Ms point or below. Next, the surface temp is recuperated to 450 to 680 deg.C by internal holding heat in the steel material. Thus, the surface layer is transformed into a tempered martensite structure and the inner part to a mixed structure of fine ferrite + pearlite or ferrite + pearlite + bainite. In this way, thermal refining in an off-line state can be obviated.

Title: Inspection of signal processor
Inventor: SHIMADA KAZUYUKI
IPC: G01R31/316
Filed: 1989-03-29
Abstract: PURPOSE:To achieve a simplification of a construction and a reduction in inspection time by inputting a processing signal to be outputted with a cycle corresponding to a deviation of first and second frequencies into an inspector to perform an inspection. CONSTITUTION:When a sampling holding circuit 11 is mounted on an inspector 12, a first input signal Si (with a frequency fi) is generated from a first input signal generation circuit 13. A sample pulse Ss is generated from a sample pulse generation circuit 14. Moreover, as the circuit 11 performs a processing of sampling and holding the signal Si at a cycle of the pulse Ss with a frequency fs, a signal waveform is obtained as processing signal Ds. In other words, the signal Ds holds a level of the signal Si in a corresponding phase at each cycle of the pulse Ss and is turned to a signal with a frequency fi-fs as a whole. The signal Ds is cleared of a high frequency component with an LPF 15 and shaped to an inspection signal Sc to be inputted inspector section 16. This achieves a simplification of a construction and a reduction in inspection time.

IPC: B28B1/04
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To make the charging density of ceramic particles more uniform without impairing the production efficiency or the like of a device by a method wherein a molding pressure can be finely adjusted without changing rollers and the weight of a hammer part. SOLUTION: The diameters of a pair of rollers 7a and 7b, the edge faces of each of which have a large diameter and a small diameter, are set to become gradually smaller from the one ends positioning at one and the same direction of a pair of the rollers 7a and 7b towards their other ends or the thickness of latched bodies are set to become gradually thinner from the one ends positioning at one and the same direction of a pair of the rollers 7a and 7b. The rising distance of a molding rod 6 is determined by the peripheral lengths of the large diametral parts of the rollers 7a and 7b. Accordingly, by moving the molding rod 6 along the axis lines of the rollers 7a and 7b, the fine adjustment of a tapping height becomes possible without changing rollers and the weight of a hammer part.  Consequently, the fine adjustment of a molding pressure becomes possible without impairing the production efficiency or the like of a device and the charging density of ceramic particles can be made more uniform.

Inventor: OSHIMA TOSHIAKI
IPC: B41J29/00
Filed: 1989-03-30
Abstract: PURPOSE:To simplify a paper ejecting mechanism and to easily and properly use face-up and face-down by arranging each processing means in such a way that a paper carrying path from paper supply to paper eject runs slantly and downwardly and using one paper ejecting guide and one paper ejecting roller for the face-up and the face-down. CONSTITUTION:The paper passing through a fixing roller 16 is guided by the paper ejecting guide 24 and ejected by the ejecting roller 21. When a signal for an electromagnet 32 is off, a switching lever 30 is fixed, the ejected paper because its path is bent is sent to a face-up tray 26. When the signal for the electromagnet 32 is on, the switching lever 30 is moved in a direction A and the paper is ejected on a face-down tray 27. By this mechanism, the face-up and the face-down are carried out by using the same paper ejecting guide and paper ejecting roller. Thus, a printer which has a simplified paper ejecting mechanism and can easily and properly use the face-up and the face-down is obtained.

Title: Direction change-over valve
Inventor: UENO KATSUMI
IPC: F16K11/07
Filed: 1982-05-11
Abstract: PURPOSE:To stabilize the operation of an actuator by arranging in a spool two check valves for affording communication between two ports connected to the actuator and opening two check valves when pressure in one port exceeds that in the other port. CONSTITUTION:Since working oil flow flowing from a port A to A tank port T is limitted by a throttle portion 25d, oil pressure in the port A is increased to open a check valve 40 in the extension of a hydraulic cylinder. When the check valve 40 is opened, pressurized oil in the port A opens also a check valve 50 to afford communication between the ports A and B so that a portion of pressurized oil in the port A is circulated to the port B to prevent pressure reduction in the port B. As a result, the extension speed of the hydraulic cylinder is regulated so that the operation of the hydraulic cylinder is stabilized.

Title: Tape cassette
Inventor: KONNO SHUNICHI
IPC: G11B23/087
Filed: 1992-02-28
Abstract: PURPOSE:To recover the deformation of spring parts and to surely lock a reel at the unused time of cassette by using a shape memory resin for the material of reel locking members. CONSTITUTION:The reel locking members 13, 14 and the spring parts 31, 32 are integrally formed by the shape memory resin. For the shape memory resin e.g. a polyurethane, the shape restoring temperature is capable of freely being set to a temperature between -30 to +70 deg.C, therefore, the shape restoring temperature in the case of using this material is set to e.g. 20-30 deg.C. Even though the deformations in such locking members 13, 14 and spring members 31, 32 are generated by the addition of a creep load at high temperature in a VTR device, the spring parts 31, 32 are recovered to those in the original shapes, since the environmental temperature becomes the shape restoring temperature when these members are taken out to the outside of the device. Consequently, both reels 5, 6 are surely locked at the unused time of the cassette.
