Title: Overvoltage protecting circuit
Inventor: KOUNO MICHIO
IPC: G05F1/56
Filed: 1983-03-09
Abstract: PURPOSE:To decrease the number of control parts and to improve the reliability of an overvoltage protecting circuit by providing a variable resistance to an output circuit of a photocoupler to control the detection level of overvoltage and therefore simplifying the constitution of a detection level control circuit with continuous variation of the detection level. CONSTITUTION:A variable resitance RV is put between the emitter and the base of a photocoupler PI. If the value of the RV is set infinite, the input and output currents If and Ic have approximately rectilinear rises with the zero point defined as a start point. The rise point of the current Ic moves to the right side as the value of the RV is reduced from the infinite value, and the current Ic has a rise approximately in parallel to a characteristic curve that is obtained when the variable resistance value is set infinite. Therefore the conditions to obtain an output current at the coupler PI can be controlled by changing the value of the resistance RV.

IPC: H01L21/60
Filed: 1995-02-28
Abstract: PURPOSE: To cut down the number of plating steps by a method wherein a solder film having lower melting point than that of solder electrode of a chip on a chip connecting side surface electrode of a package so that the melting point of the solder at the connecting part formed by the fusion-junction of both elements is made higher than that of the solder connecting the package to a substrate. CONSTITUTION: A solder film 1 in thickness of 3-10μm and Sn content of 63wt% is formed on a chip connecting side surface electrode 22 formed on a package 21. Next, when a solder electrode 25 about 150μmϕ and Sn content of 5wt% formed on a chip bottom surface is mounted on the electrode 22 so as to be fusion-junctioned at about 340 deg.C, the solder 2 in the junction part becomes Sn 6-8wt% making the melting point higher than that of the solder between the package 21 and the substrate, thereby enabling the possibility of causing defective junction when they are junctioned with each other to be avoided. Through these procedures, the chip and the package can be connected by only one plating step of the solder film, besides, enabling the plating step to be eliminated by immersing in a fusion soldering vessel.

IPC: G11B5/02
Filed: 1988-02-22
Abstract: PURPOSE:To attain the high speed switching of a large magnetic field and to realize over-write function by electrically parallelly connecting an (n)-number of coils to a U-shaped high permeability magnetic substance, which faces to both sides in the end face of a magneto-optical disk. CONSTITUTION:In the middle of a high permeability magnetic substance to face to both surfaces of a magneto-optical disk 5 and to be U-shaped by being returned in an end face part, three-terminal coils 2 and 3 to be electrically parallelly connected are provided. For the coils 2 and 3, one side terminals are connected and by alternatively causing a current to flow to both parallel coils 2 and 3 by an electromagnet driving circuit 4, an impressing magnetic field is given in the vertical direction of a recording medium 5. Since the coils are parallelly connected, the inductance of the coil is widely decreased. Accordingly, since the rising time of the recording current is made small by the small inductance, the switching speed of the magnetic field can be made high. Then, without needing batch erase, the over-write performance, which can directly execute desired recording, can be realized.

Filed: 1980-03-31
Abstract: PURPOSE:To improve the accuracy and quality of polishing a thin work, by spouting gas around a face of adsorption on the work for preventing abrasive fluid from entering onto the face. CONSTITUTION:A supporting jig 2 is composed of a main body 7, decompression unit 13 and gas feeder 42.

Title: Sheet to be thermally transferred
Inventor: SAGANE MASAYOSHI
IPC: B41M5/50
Filed: 1999-02-18
Abstract: PROBLEM TO BE SOLVED: To upgrade light resistance of an image formed by transfer of a dye and to improve blocking properties by incorporating a hindered amine optical stabilizer represented by a specific structural formula in a receiving layer. SOLUTION: A hindered amine optical stabilizer represented by a specific structural formula (wherein R is a hydrogen atom or an organic substituent) is incorporated in a receiving layer formed on one main surface of a sheet-like base material of the sheet to be thermally transferred. An adding amount of the stabilizer contained in the layer of a range of about 1 to 50 pts.wt. is good. If the adding amount is less than 1 pt.wt., its light resistance upgrading effect becomes insufficient. Conversely, if it exceeds about 50 pts.wt. maintaining of coated film physical properties of the layer becomes difficult, stickiness is incorporated, and feeding in a printer due to deterioration of the physical properties of the layer becomes impossible.

Abstract: PURPOSE: To perform stable soldering to the portions to be soldered of electronic parts by a simple method by raising the temperature of at least the portion to be soldered to the melting temperature of solder then depositing and melting the flux- containing solder powder in this portion.  
     CONSTITUTION: At least the portion to be soldered of an electronic part whose surface is required to be formed with a solder layer is heated to be raised of its temperature to the melting temperature of solder, e.g., 300W500°C.

In this way, the formation of the solder layer as well as the  connecting, bonding and securing of the articles to themselves are finished. With  this method, always a fixed amount of the flux contained in the solder powder  blows out from the solder powder and therefore the stable soldering work may be  done without any increase or decrease in the flux amount. In addition, it provides  advantages such as the elimination of the need for cleaning of flux and further the  elimination of the need for any jigs and soldering iron.
