Title: Surface treatment method
Inventor: KANZAWA YASUHIRO
IPC: C09D5/00
Filed: 1997-02-19
Abstract: PROBLEM TO BE SOLVED: To improve the adhesion in a bonding or coating operation without increasing the surface treatment cost by coating the surface of an object to be treated made of an iron material, a stainless steel material, or an aluminum material with a surface-treating agent contg. phosphoric acid and ethyl alcohol and leaving the coated surface standing for a specified time. SOLUTION: The surface treating agent is prepd. by compounding 20-35wt.% phosphoric acid, 50-70wt.% ethyl alcohol, and a necessary amt. of a viscosity modifier. The surface of an object to be treated made of at least one material selected from among an iron material, a stainless steel material, and an aluminum material is slightly polished, washed with a volatile org. solvent, then coated with the surface treating agent, and left standing for 1min to 48hr. Thus treated object is adhered to another object this treated with an adhesive, or thus coated surface is further coated with a corrosion-resistant resin material.

Abstract: PURPOSE:To enable the use of an iris diaphragm in the regulation of the quantity of light by setting a half mirror in front of a concave mirror in an oblique state to the optical axis. CONSTITUTION:Incident luminous fluxes are passed through a half mirror 2, reflected by a concave mirror 1, further reflected by the mirror 2, passed through a hole 4 for taking out luminous fluxes, and subjected to the regulation of the quantity of light with an iris diaphragm 3 to form an image on an image forming surface 5. To reduce the telephoto ratio the mirror 2 is made convex. Since the luminous fluxes used to form the image are circular in cross- section, the iris diaphragm can be used in the regulation of the quantity of light.

Title: Printer
Inventor: SHINANO TOSHIHARU
IPC: B41J19/68
Filed: 1984-03-19
Abstract: PURPOSE:To enable staggering in printing position to be corrected, by a method wherein when a printing head does not reach a reference position over a plurality of lines, the head is scanningly moved to the reference position for each preset number of lines, and a reference position is reset. CONSTITUTION:Printing data supplied from a data-inputting part 9 are stored into a buffer memory 10, and a controlling part 8 scanningly move the printing head 1 in the line direction by a driver 7 and a motor 3 while referring to and renewing a head position parameter stored in a memory part 8d. Where the printing data have such a construction that the head 1 reaches the reference position for printing, the printing position is confirmed or reset each time the head reaches the reference position. Although printing is continued without reaching of the head to the reference position in a certain construction so as to enhance printing efficiency, there is possibility of entanglement of the printing paper or the like. Therefore, when it is detected by a detector 5 that the head has reached the reference position, a line number N is set in the memory part 8d, and when the number of lines printed reaches N, the head 1 is moved to the reference position, and the reference position is confirmed and reset.

Abstract: PURPOSE:To guarantee the output source voltage of a common DC power source part to be within a safe operation range at all times when a main shaft motor driving control part and a feed shaft driving control part stop or enter deceleration operation at the same time. CONSTITUTION:The DC power source part 10 rectifies and smoothes AC input electric power. The DC electric power supplied from the DC power source part 10 is converted as required to supply driving electric power to a main shaft motor 2a.

Title: Manufacture of semiconductor pressure sensor
IPC: G01L9/00
Filed: 1992-03-12
Abstract: PURPOSE:To prevent segregation of sodium on the surface of a metalized layer formed on the other side of a glass spacer by bonding a pressure-sensitive silicon chip and a glass spacer at a specific temperature with electrostatic bonding method, and after that, impressing, between the chip and the glass spacer, a DC voltage reverse to the impressed voltage at the time of electrostatic bonding, while keeping the temperature, and finally cooling the chip and the glass. CONSTITUTION:A pressure-sensitive silicon chip 1 forming distortion gauge for converting pressure into an electric signal on a diaphragm portion is bonded to one side of a glass spacer 2 by electrostatic bonding. After that, while keeping the bonding temperature, DC voltage reverse to the voltage at the time of bonding is impressed between the chip 1 and the glass spacer 2, which are afterwards cooled in a furnace. Therefore, sodium, which moved within the glass at the time of electrostatic bonding, is not segregated on the metalized layer surface of the other side of the glass spacer. As a result, the glass spacer 2 can be soldered to the metallic member even if it is not cleaned. In addition, simplification, reliability, and cost performance are improved. In this case, it is effective to impress the voltage of opposite direction immediately after electrostatic bonding.

Title: Vacuum circuit breaker
Inventor: YORITA MITSUMASA
IPC: H01H33/66
Filed: 1990-03-05
Abstract: PURPOSE:To increase mechanical strength of an electrode by arranging a reinforcing plate of mechanical strength greater than that of a contact material at the back portion of a contact, and arranging a joint portion in the vertical direction to the mutual contact face of the contacts near the outside diameter of the contact so as to be joined to the contact. CONSTITUTION:A moving contact 2 and a fixed contact 3 are arranged in a vacuum vessel so as to be connectable to and dis-connectable from each other. Reinforcing plates 21A and 31A each comprising a material of mechanical strength greater than that of the contact material of the moving contact 2 and the fixed contact 3 used therein are arranged respectively at the back portion of the moving contact 2 and at the back portion of the fixed contact 3. Then a joint portion in the vertical direction to the mutual contact face of the moving contact 2 and the fixed contact 3 is formed near the outer diameter of each of the contacts 2 and 3. Since the direction of the outer-diameter end of the joint portion may discord with impact force given when each of the contacts is opened and closed by arranging each of the reinforcing plates in such a shape as to be embedded in each corresponding one of the contacts in this manner, the soldered material at the joint portion may be difficult to be cracked while the development of a crack may be difficult even if the crack occurs in the outer-diameter end part of the joint portion. An electrode can thus be manufactured with great mechanical strength.
