Title: Head for perpendicular magnetic recording and reproduction
Inventor: KOU HIROYOSHI
IPC: G11B5/187
Filed: 1988-04-25
Abstract: PURPOSE:To improve the durability of the title head and, at the same time, to obtain a sufficiently large signal so as to further improve the characteristics of the head by holding a main magnetic pole by means of a head holding member of a hard material through an insulating film and specially designing the shape of the front end of the main magnetic pole. CONSTITUTION:Orthogonally intersecting grooves 2 and 3 and 4 and 5 are formed in the upper end section of a ferrite core 1 and a main magnetic pole 8 is integrated to the upper end surface of a projection 6 of a square pillar at the center surrounded by the grooves 2, 3, 4, and 5. The main magnetic pole 8 is surrounded by a head holding member 9 of a hard material, such as a ceramic material, etc., and held by the member 9 through an insulating film 10. The front end surface of the main magnetic pole 8 is made lower than the front end surface of the holding member 9 by d1 and protruded from the front end surface of the insulating film 10 by d2. Since a recording medium is mainly slid on the surface of the head holding member 9, wear of the main magnetic pole 8 can be prevented and, therefore, a magnetic head for perpendicular magnetic recording and reproduction whose output level hardly drops even when the head is used for a long time and which is excellent in durability can be obtained.

Title: Rolled pressure-sensitive adhesive tape and production thereof
Inventor: TANAKA MIKIO
IPC: C09J7/02
Filed: 1984-05-21
Abstract: PURPOSE:To obtain a rolled pressure-sensitive adhesive tape on which a guide paper is sticked so that its end can be easily taken out, by applying a pressure sensitive adhesive to a tape substrate, traveling the tape and cutting it from the side of the substrate at a specified position behind a folding line. CONSTITUTION:The fixed guide paper is cut into lengths with a cutter 8 and moved in the direction of the arrow of a pushing plate 11, whereby the cut paper is folded at a predetermined angle around a folding line C at a folding part 5.

Title: Dynamic pressure type gas bearing
Inventor: ASADA TAKAFUMI
IPC: F16C32/00
Filed: 1990-04-18
Abstract: PURPOSE:To eliminate seizure of a bearing caused by dust or particulates by constituting the bearing of a sleeve, which is supported at the outside of a shaft body in a freely rotatable manner, and a lid, which is fixed to an end of this sleeve, and providing a small-diametral projected part to one side of the shaft body together with providing a herringbone groove and a connecting hole, which connects the highest pressure part of the groove to a free end surface of the shaft body, to both a periphery of the shaft body and one side of the inner periphery of the sleeve. CONSTITUTION:When a stator 4 is electrified, a rotor 5 rotates, and a sleeve 3, a lid 7, and a polygonal mirror 9 also rotate at a high speed. The pumping action of a herringbone groove 2 increases the pressure of the gas between the groove 2A and the sleeve 3, so that the sleeve 3 rotates without contact. A part of the gas is led from a peripheral groove 2B to a connecting hole 2C and then introduced into a free end of the shaft body. After this, the gas goes through a restriction member 8 having a fine hole and blows up against the lid 7, thereby generating the floating force in the direction of 'A'. Both the weight of the revolving body and the force, with which the stator 4 is sucked by a rotor magnet 5, act in the direction 'B'. At this time, the floating force and these two forces cancel each other, resulting in the floating-up by 'C'. Since the gas is compressed in a gap of the bearing, dust or particulates are prevented from going from the stator 4 into the bearing gap. Thus, the gas bearing will never be seized.

Title: Analysis system for sentence structure
Inventor: KISHIMOTO YOSHINORI
IPC: G06F9/45
Filed: 1986-05-06
Abstract: PURPOSE:To perform analysis of sentence structures with a single parser set for plural sentence structures by using a parser that adds a single sentence structure rule for each subject of analysis of sentence structure against a sentence structure rule that describes the grammar of a program language. CONSTITUTION:A sentence structure rule of S N1 is added to each sentence structure element N1 to undergo the sentence structure analysis. In this case, S means a special sentence structure symbol called a start symbol. Then an initial state is produced based on each added sentence structure rule and a state transition chart is produced based on said initial state for production of a parser. For the analysis procedure where the parser is applied to a structure editor, an initial state is first set for analysis of sentence structure. Then the state transition is carried out while the input source is read. Thus it is discriminated whether the state is shifted normally or not. If so, the input source is fetched and put into a proper place within an existing source. While a message is outputted for a detected error to urge a user to correct the source if the state transition ends in an abnormal state.

IPC: H01S5/00
Filed: 1993-04-28
Abstract: PURPOSE:To reduce a resistance of a p-electrode of a p-type II-VI semiconductor containing sulfur (S) or >=um (Se). CONSTITUTION:This embodiment comprises a chirp super-lattice 4 composed of a metal and a p-type semiconductor between a p-type II-VI semiconductor layer 3 and a p-electrode 5, and the closer to the p-type semiconductor layer 3 a location of a valence election of the chirp super-lattice 4 becomes, the deeper it becomes. Thus, a hetero barrier between the p-electrode and the p-type II-VI semiconductor layer disappears to readily implant positive holes and reduce a resistance in the electrode.

Title: Complementary d flip-flop circuit
Inventor: AIDA TOMIO
IPC: H03K3/356
Filed: 1986-05-06
Abstract: PURPOSE:To attain stable operation without being affected by a control pulse due to the delay of pulses of positive and negative phases generated by a biphase control pulse by seting the current drive capability of an inverter to 1/4 or below of the current drive capability of a feedback circuit inverter. CONSTITUTION:In designing the transistor size of an inverter 8' to be 4a or more with respect to the transistor size (a) of an inverter 5 so that the current drive force of the inverter 5 at the master side is 1/4 or below of the current drive force of the inverter 8' at the slave side, even when, a transfer gate 3 is conductive by the overlap due to the delay of pulses of positive and negative phases generated by a biphase control pulse circuit, the potential at a node 9 does not exceed the threshold potential of an inverter 7. Further, the current drive force is almost selected by the channel width of a MOS transistor. Thus, the titled complementary D flip-flop is obtained, which is operated stably in a way that input data DIN is outputted from output terminal Q with a prescribed time of delay synchronously with biphase control pulses CK, the inverse of CK.

When the gas is blown off, a surface temperature of the water 5 is raised and the surface temperature of the wafer 5 in a film formation region is made uniform. Thereby, it is possible to set a film quality in a depth direction of the film uniform when the film is formed; accordingly, reliability of the film quality can be enhanced.

IPC: H01L23/532
Filed: 1992-03-28
Abstract: PURPOSE:To enhance the electromigration resistance of an interlayer junction within the multilayer wiring structure of the integrated circuit device. CONSTITUTION:An insulating film 16 is formed on an insulating film 12 covering the surface of a semiconductor substrate 10 through the intermediary of a lower wiring layer 14 comprising Al or Al alloy and then an upper wiring layer 18A comprising Al or Al alloy is formed so as to be connected to the lower wiring layer 14 through the intermediary of a connecting hole Qa on the insulating film 16.
