Inventor: ARAI YUU
IPC: B26B9/00
Filed: 1983-04-28
Abstract: PURPOSE:To produce easily a blade which is coated with a carbide at the tip and has excellent cutting quality and durability by covering the part, except the tip, of the blade consisting of an iron alloy having carbon at a relatively high rate and dipping the blade into a molten salt bath contg. a carbide forming element then hardening the tip. CONSTITUTION:A blade 1 consisting of an iron alloy contg. >=0.2wt% carbon is coated thereon, except the part near 0.01-1mm. from the tip 11 thereof, with a masking agent 2 which is stable to dipping in a molten salt bath. Such blade 1 is thereafter dipped in the molten salt bath contg. a carbide forming element such as IVa group and Va group elements, Mn, or the like to form a carbide layer only on the surface of the tip 11, then the blade is removed from the bath and is subjected to hardening by oil quenching. The treating agent and masking agent sticking on the surface are removed by washing with hot water.

Title: Liquid pressure piston device
Inventor: HASEGAWA HISAO
IPC: F04B1/113
Filed: 1989-03-29
Abstract: PURPOSE:To construct a liquid pressure piston device in a simple and small size and enhance the durability by providing a plurality of pistons which are arranged in a rotor radially and in which a piston head contacts the periphery of an eccentric shaft at all times, and furnishing a baffle means arranged in contact with the inlet/outlet for the working fluid. CONSTITUTION:A stator ST and a cam C as eccentric shaft are fixed, and when a rotor R rotates clockwise, a piston P1 is moved toward the center along the cam c by a spring in the initial period of rotation so as to suck in the working fluid from a port A. In the same manner a piston P3 performs sucking motion from the port A, while a piston P2 moves outward to exhaust the working liquid to another port B. The pistons P repeat suction and exhaust of the working liquid in the condition that the phases are shifted 120deg., wherein grooves A1, B1 function as a rectifier, and synthetization of influx and flowout of the working liquid about the pistons presents such that the port A sucks in the working liquid while the port B discharges continuously. This achieves a liquid pressure piston device in a simple structure and equipped with durability.

Title: Writing circuit of magnetic head
Inventor: MATSUURA MICHIO
IPC: G11B19/04
Filed: 1981-05-18
Abstract: PURPOSE:To easily detect disconnection without increasing the numbr of leader lines of a magnetic head, by simplifying the leader line and circuit from a multichannel magnetic head. CONSTITUTION:One magnetic head HD is constituted of 4 current sources E, which consist of 2 flow-out type current sources E0 and 2 suction type current sources E1. By turning on and off a pair of E0 and E1 among them, a current is made to flow in two directions to a magnetic head. In this case, even if the magnetic head is connected in series, no influence is exerted on an adjacent magnetic head. If one magnetic head in the magnetic heads HD connected in series has been disconnected, the current source of its magnetic head loses its corresponding current source (a corresponding current source of E0 and E1), therefore, a current flows to a resistance Rc. Therefore, since the potential of the Rc is varied largely, disconnection can be grasped by detecting its variation.

Title: Data compressing device and data restoring device
Inventor: NAKANO YASUHIKO
IPC: H03M7/42
Filed: 1993-04-02
Abstract: PURPOSE:To enable high data compression by generating codes by using longer data between the longest matching character string and a dictionary number when input data can be compressed or only the dictionary number when not. CONSTITUTION:The data compressing device 1 should add a discrimination flag when the data are encoded with the shorter data between the longest matching character string and dictionary number. For the purpose, the codes are generated according to a mixed mode wherein the shorter data between the longest character string and dictionary number is used when the input data stored in a buffer 11a can be compressed in spite of an increase in code length resulting from the discrimination flag. When the data can not be compressed, the codes are generated according to an original single mode wherein only the dictionary number is used. Consequently, the high data compression becomes possible. Further, the data restoring device 2 performs conversion processing reversely to the data compressing device 1 to restore the code words generated by the data compressing device 1.
