Title: Production of magnetic head
Inventor: KITATANI AKIO
IPC: G11B5/31
Filed: 1990-06-04
Abstract: PURPOSE:To decrease the number of the times to exchange deformed blates by using the finishing by dicing in which a V-shaped blade is used and preworking by dicing in which a square blade is used to form grooves. CONSTITUTION:The plural grooves 11, each having an approximately V-shaped section, are formed adjacent and parallel to and with each other on the surface of a substrate 1 having a approximately rectangular parallelepiped shape at the pitch size A taking the final thickness of a magnetic head and the margin for cutting at the time of parting into consideration. The dicing to execute grinding and polishing by rotating the disk blade provided with a polishing material on the outer peripheral edge part is used as the grooving on the substrate 1 which is resistant to wear and is, therefore, high in hardness and is hardly workable. The square blade having a square sectional shape in the outer peripheral edge part is first used as preworking of the grooving using this working method. The square grooves 11b are continuously formed in the direction perpendicular to the surface prior to the working of the substrate 1 at the depth slightly shallower than the finish size and at the pitch size A.

Title: Paper feed roller
Inventor: TORII HIDEYASU
IPC: B65H5/06
Filed: 1990-06-05
Abstract: PURPOSE:To maintain desirable paper feeding performance for a long period of time by mixing a fibrous or needle like inorganic filler in a range of at least 10mum from the surface of a roller. CONSTITUTION:A paper feed roller formed of synthetic resin molded into a roller shape is provided with a fibrous or needle like inorganic filler mixed in a range of at least 10mum from its surface. The weight percent ratio of resin/ filler is to be in a range of 95/5-60/40. The inorganic filler is therefore exposed on the roller surface, so that a friction coefficient to paper becomes extremely high. Accordingly, even if high-hardness elastomer excellent in durability such as abrasion resistance is used as roller molding material, a sufficient friction coefficient can be obtained, and therefore an excellent friction coefficient can be maintained with little adhesion of paper powder.

Title: Vertical articulated robot
Inventor: NIHEI AKIRA
IPC: B25J9/06
Filed: 1996-05-17
Abstract: PROBLEM TO BE SOLVED: To easily form an arm direct-acting type robot as a fixed link type robot. SOLUTION: Links 10, 11, 12 and so forth are added to an arm direct-acting type robot without changing a robot mounting base 1, thereby forming a fixed link type robot. Also, an extension arm 15 is added to the second arm 15 having a robot wrist at a forward end, thereby increasing arm length for preventing the reduction of a working operation range. Also, the base 3 of the second wrist is turned around an axis offset from a slewing center, thereby minimizing an increase in interference radius. Furthermore, the change of the arm direct- acting type robot to the fixed ring type robot enables a robot wrist part to cope with a portable weight increase.

Title: Ink jet recorder
Inventor: MAKINO MASAYUKI
IPC: B41J2/12
Filed: 1979-11-14
Abstract: PURPOSE:To provide the titled recorder capable of obtaining a constantly fixed deflection amount and suitable for printing those pictures which require a strict printing precision and for color printing, while said recorder being provided with means for detecting the flow velocity of ink and compensating for the difference between the detected flow velocity and a reference flow velocity. CONSTITUTION:The flow velocity of the ink jetted from a nozzle 10 is detected by the detecting means 11, the detected signal being amplified by a buffer amplifier 12 and inputted into a comparator 14. The detected value of the flow velocity is compared with the reference value fed from a reference-voltage generator 13. When there is a difference between the two values being compared, the pressure of an ink pump 15 is changed to change the flow velocity of the ink so as to compensate for the difference, thereby maintaining a constantly fixed flow velocity. A pressure- sensitive element 17 can be used as the detecting means 11 for detecting the flow velocity of the ink. The deflection amount can be maintained at a fixed value also by changing the voltage for charging ink droplets in accordance with the flow velocity of the ink.

Filed: 1981-09-18
Abstract: PURPOSE:To easily decrease surface resistance by electrolytic plating of a low resistance metal layer on the substrate under the predetermined plating condition in place of covering the operating layer and metal electrode part with the plating preventing insulator. CONSTITUTION:Since the substrate 4 has a lower specific resistance than that of the operating layer 1, a low resistance metal layer 6 is formed preceding the operating layer 1 on the substrate 4 when the electrolytic plating is executed. The metal layer 6 can be formed only on the substrate by setting voltage, current values of electrolytic plating to the particular conditions. Therefore, the insulator for preventing plating is coated on the surface of operating layer 1 and metal electrode portion. Thereby, it is no longer necessary to remove it after the plating and deterioration of characteristic by contamination and difficulty in wiring are not generated. In addition, even when such insulator is coated after a device is mounted into the case consisting of the ceramic 7 and metal material 8 and wirings are performed, a low resistance metal layer 6 can be formed on the substrate 4 and metal part 8 and thereby apparatus characteristic can be outstandingly enhanced.

Abstract: PURPOSE:To improve a coupling efficiency between a distributed feedback laser and an optical element and provide sufficient electrical isolation by a method wherein the coupling part and the channel part of the distributed feedback laser are filled with high resistance semiconductor which is transparent at the oscillation frequency of the laser. CONSTITUTION:The channel part 140 and the coupling part 120 of a distributed feedback laser (DFB laser) 110 are filled with high resistance semiconductor 107 and a light guide layer 102 is formed over a whole device.

Moreover, as the channel part 140 of the DFB laser 110 is also filled with the high resistance semiconductor 107, a lateral mode can be stabilized and a current can be suppressed to a low level so that the laser with a low threshold and a high efficiency can be obtained. It is to be noted that the DFB laser 110 has a so- called strip buried hetero structure (SBH structure).

Abstract: PURPOSE:To synthesize uniform silicon carbide powder containing a desired amount of free carbon, by controlling acetylene which is a reaction by-product on synthesizing the silicon carbide powder in the vapor phase at a high temperature. CONSTITUTION:Argon gas is introduced from a gas inlet pipe 3 for plasma to carry out electric discharge between cathode 1 and anode 2 and generated plasma.
