Title: Caliper display method
Inventor: MACHIDA ETSURO
IPC: A61B8/00
Filed: 1992-12-15
Abstract: PURPOSE:To display multichannel caliper without reducing responsiveness only by using two sheets of image memory planes. CONSTITUTION:When the starting point and the end point of a caliper is specified, the distance from the starting point to the end point is displayed on a display unit 13.

Title: Clock generator and its production
Inventor: YOSHINAKA KATSUNORI
IPC: H03L7/183
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To reduce the chip size and the cost of a clock generator by preparing a 1st and/or 2nd trimming switch means which sets the division ratio of a 1st and/or 2nd programmable counter by trimming and using a fuse or laser trimming element to the trimming switch means. SOLUTION: The 1st and 2nd programmable counters 1 and 2 divide the reference clock generated by a crystal oscillator XTALOSC 10 and the clock output CK generated by a voltage controlled oscillator VCO 8 to output a reference signal R and a feedback signal F respectively. A phase comparator 6 compares both signals R and F with each other to produce a phase difference signal P which controls the VCO 8 via a drive means 7. The 1st and 2nd trimming switch means 3 and 4 fix the division ratios of both counters 1 and 2 by trimming and by means of the fuse or laser. Thus, the mask production cost is reduced and the frequency is easily set.

Abstract: PURPOSE:To prevent a tombstone phenomenon by a method wherein, in the welding operation of a creamy solder, the wettability of the solder at the vertical edge part of an electrode is lowered and a terminal part to which the solder does not adhere is formed. CONSTITUTION:When an electrode 3 is fixed and bonded to a pad 5 by using a solder 6-1, a vertical edge part 3A at the electrode 3 is formed in such a way that the wettability of the solder is worse. Thereby, the solder 6-1 does not adhere to the edge part 3A. In order to form the edge part 3A in such a way that the wettability of the solder is worse, a solder layer 7 which is formed on the edge part 3A by a preliminary soldering operation is formed in such a way that a metal layer 8 such as stainless steel or the like is laminated or that an insulating layer 9 by a silicon compound is laminated. In addition, the solder layer 7 which has been formed by the preliminary soldering operation is removed at the edge part 3A, and a conductive material 3-1 which forms the electrode 3 is exposed from the edge part 3A. Thereby, it is possible to prevent a tombstone phenomenon in a bonding operation.

Abstract: PROBLEM TO BE SOLVED: To prevent cold water flow paths from being iced during the stopping of operation of an absorption air conditioner. SOLUTION: In an absorption air conditioner, an absorption heat source unit which performs a cooling operation in an absorption cycle comprising a regenerator, a condenser, an evaporator, an absorber, and an absorption liquid pump, and which opens a directional control valve for cooling/heating in a heating operation to feed a heated absorption liquid to the evaporator from the regenerator through a heating absorption liquid flow path, is connected to air-conditioning heat exchangers 44 of indoor units RU through cold water flow paths 47 having a cold water pump. In the case where an external air temperature is low, a cold water inlet thermistor 49 is provided in each indoor unit RU.  When a cold water temperature is lowered down to 20 deg.C or below, a gas burner is ignited according to the external air temperature, and the cooling/heating directional control valve is opened to heat cold water with the heated absorption liquid and to allow cold water thus heated to circulate through the cold water flow paths 47. Thus, before the cold water flow paths are iced due to drop of a cold water temperature, the cold water temperature can be increased, and icing can be prevented.
