IPC: G06F3/0488
Filed: 1994-07-27
Abstract: PURPOSE:To provide a position detector capable of preventing the generation of a deviation in a coordinate value due to induced voltage remaining in a circuit. CONSTITUTION:One loop coil out of plural loop coils arranged in parallel in a position detecting direction is scanned/selected to transmit/receive a radio wave (S1), the approximate position of a position indicator is found out based upon induced voltage generated in respective loop coils (S3), and in the case of successively scanning/selecting each loop coil by the prescribed number of loop coils around a loop coil generating maximum induced voltage and transmitting/receiving radio waves, its selecting direction is alternately switched and selected (S5, S6) and the coordinate value of an indicated position based upon the induced voltage generated at the time of switching the selecting direction is averaged (S8). Consequently a deviation of a coordinate value due to the influence of induced voltage remaining in a resonance circuit in the position detector can be canceled.

Title: Vertical thin film magnetic head
Inventor: OODOI YUUZOU
IPC: G11B5/31
Filed: 1985-08-09
Abstract: PURPOSE:To reduce the concentration of the magnetic flux at the tip part of an auxiliary magnetic pole near a main magnetic pole and to eliminate the regular noises, by applying a groove cutting process to a magnetic substrate serving as an auxiliary magnetic pole and filling a nonmagnetic substance into the groove to separate the rubbing surface of a medium from the tip part of the auxiliary magnetic pole. CONSTITUTION:A groove is cut to a magnetic substrate 1 of ferrite, etc. with depth D and width W and a nonmagnetic substance 9 of glass, etc. is filled into the groove. The width W is larger than the spacing value H that is needed between a medium rubbing surface 8 and the tip of the auxiliary magnetic pole. While the depth D is decided so that the most of the magnetic flux can flow well up to the depth D at the tip part of the auxiliary magnetic pole. Thus the concentration of the magnetic flux is avoided at a part B of the groove bottom as long as the depth D is sufficient. This prevents the concentration of magnetic flux at the tip part A of the auxiliary magnetic pole near a main magnetic pole.

IPC: G06F17/22
Filed: 1994-07-28
Abstract: PURPOSE:To easily prepare a document wherein characters of different kind from KANA(Japanese syllabary) characters are mixed without a need to switch input character kinds. CONSTITUTION:The document preparation device equipped with a keyboard 11 which has English characters assigned to keys for inputting KANA characters and inputs character data by switching an input character kind to KANA characters or English characters through shift operation registers a currently inputted word in a user dictionary 15 in the form of the reading of the KANA characters by a different character kind automatic registration processing part 13 at the timing when the input character kind of the keyboard 11 is switched to English characters. When this word is inputted thereafter in the form of the reading of the KANA characters, a KANA-KANJI(Chinese character) conversion processing part 16 reads the word out of the user dictionary 13 on its reading and outputs the word. Consequently, when the same word is inputted for a 2nd time or later, the need to switch the input character kind is eliminated.

Title: Ac-ac converter
Inventor: TSUGITA KAZUHIKO
IPC: H02M7/48
Filed: 1994-07-28
Abstract: PURPOSE:To realize a high power factor, suppress the harmonics of a power supply and reduce the loss of a switching device by a method wherein a 7th capacitor is connected between the connection point of a 1st diode and a smoothing capacitor and the connection point of a discharge lamp and a ballast choke. CONSTITUTION:A 7th capacitor is connected between the connection point of a 1st diode D1 and a smoothing capacitor C2 and the connection point of a discharge lamp FL and a ballast choke TB in a converter. When a commercial AC power supply AC is closed, a radio frequency current is made to flow and a resonance voltage is induced across a starting capacitor C4 by the series resonance of the ballast choke TB and the starting capacitor C4 to ignite the discharge lamp FL. Although the radio frequency current flows even if the discharge lamp FL is on, as the impedance of the discharge lamp FL in low in the parallel circuit of the discharge lamp FL and the starting capacitor C4, the current flows mainly through the discharge lamp FL. As a result, an AC-AC converter whose circuit construction is simple, whose switching device has only a small loss and which has a high power factor over a low and high frequency range can be obtained.

Title: Control valve for variable displacement compressor
Inventor: KAWAMURA CHUICHI
IPC: B01D35/02
Filed: 1993-07-16
Abstract: PURPOSE:To prevent foreign matter such as abrasion powder, produced at the sliding part of a compressor, from biting into a valve seat so as to make displacement control positive by disposing a filter means at each port of a control valve communicated with each chamber of the compressor. CONSTITUTION:In a control valve 30, a low pressure chamber 51 communicated with the intake chamber of a compressor by a communi-cating path 22a is expanded when intake pressure Ps exceeds the specified pressure, so that a diaphragm 33 ascends. As a result, a ball 45 is seated on a high pressure valve seat 30a and separated from a low pressure valve seat 30b. Refrigerant gas in a crank chamber in the compressor is thereby led into the intake chamber through an intake passage 20, a filter 61, a control port 55a, a control passage 55, the low pressure valve seat 30b, a low pressure passage 54, a low pressure port 54a, a filter 62 and a communicating path 22b. Foreign matter such as abrasion powder produced the sliding part of the compressor at this time is caught by the filter 61 so as to be prevented from moving to the low pressure valve seat 30b. The seating and separation of the ball 45 is thereby performed smoothly, and displacement control is performed positively.

IPC: B23K20/02
Filed: 1998-06-24
Abstract: PROBLEM TO BE SOLVED: To improve thermal conductivity by forming a copper sheet composite material by providing a base wherein a copper-plated layer is formed on one side, and joining a copper sheet to one side of the base with the copper-plated layer therebetween. SOLUTION: A copper sheet composite material is formed by laminating a nickel-plated layer 2 and a copper-plated layer 3 on one side of an aluminum base 1. The nickel-plated layer 2 is formed to improve bond strength between the aluminum base 1 and the copper-plated layer 3. A copper sheet 6 is joined to one side of the base 1 with the copper-plated layer 3 therebetween. The joining is performed by metal diffusion between the copper sheet 6 and the copper-plated layer 3. Thereby, a thermal conductivity of the copper sheet 6 is twice as high as that of aluminum, and the thermal conductivity is improved. A metal-plated layer is not required on a surface of the copper sheet 6, and the bond strength is improved by approximately 50%.

Title: Forming method of via-hole
Inventor: ARAI YOSHIMITSU
IPC: H05K3/00
Filed: 1988-07-18
Abstract: PURPOSE:To omit the process of photolithography and form a via-hole through a smaller number of processes by forming a large hole and a small hole in an organic resin insulating film and an organic resin film respectively through transpiration reaction, and removing unnecessary conductor films. CONSTITUTION:An organic resin film 7 is formed on the surface of another organic resin insulating film 3. Light 8 with a wavelength which both insulating film 3 and resin film 7 absorb and by which they are photolyzed is radiated onto a specified position of the resin film 7 surface, and the resin film 7 and insulating film 3 are removed through a transpiration process in which molecular bond is optically cleaved directly and the photolyzed materials are evaporated. A conductor film 61 is formed on the surface of the resin film 7, and a conductor film 6 is formed in one body on the surfaces of a large hole H2 and a small hole H1, through sputtering. By removing the resin film 7, a lift-off process which removes the conductor film 61 on the resin film 7 too simultaneously is performed to finish a via-hole. This makes it possible to omit the process of photolithography and to form the via-hole with a smaller number of processes.
