Patent JP-2001030130-A (JP)
Title: Machine tool
Inventor: NIITANI HARUHIKO
IPC: B23Q1/70
Filed: 1999-07-19
Abstract: PROBLEM TO BE SOLVED: To prevent positional displacement and chatter of a main shaft head and to prevent heat expansion of the main shaft head by rotation of a main shaft from extremely increasing load on a guide, by providing a saddle with a pressing member for pressing the main shaft head onto a guide with an elastic force. SOLUTION: A pressing member 5 presses a main shaft head 4 through a guide 10c downward by its previous load F0. The pressing member 5 applies the previous load F0 to the main shaft head 4 so that the load onto the guide 10a is always in a stable region. Thus, even when the main shaft head 4 moves forward and the load applied to the guide 10a due to self weight or cutting resistance of the main shaft head 4 becomes near 0, a half of the previous load F0 operates. As a result, vertical displacement of the main shaft head 4 is small, and positional displacement and chatter of the main shaft head 4 hardly occur.

Title: Cut material supporting device for water jet cutting device
Inventor: SUZUKI YASUHIRO
IPC: B26F3/00
Filed: 1991-07-19
Abstract: PURPOSE:To perform reliable support of a weak raw material by filling the inner part of an upper surface opening-shaped container with granular members to form a cutting surface plate, in a cutting material support device for a water jet cutting device for a metallic material. CONSTITUTION:A cutting surface plate 9 to cut a work W through injection of high pressure water through a nozzle 8 is formed such that a partition case 13 is arranged in a container 12 the upper part of which is opened. The partition case 13 is formed of a water permeable material, such as a sintered metal, and the interior thereof is filled with granular substances 14, such as sand. The container 12 the upper surface of which is opened is placed on an exciting device 15 for excitation and the bottom thereof is connected to a water pressure generating device 11 and water injected through the nozzle 8 is circulated. In this constitution, the work W is brought into entirely uniform contact with the granular substance 14 and supported thereby. Influence is prevented from being exercised on a jet water flow through the high pressure water injection nozzle 8 and high-precise cutting can be carried out. Further, the horizontal plane property of a granular substance surface is held by excitation.

Title: Control method for electrification of glow plug
Inventor: YAMAMIYA OSAMU
IPC: F02P19/02
Filed: 1982-11-22
Abstract: PURPOSE:To control an effective voltage, applied on a glow plug, so that it is made uniform indepenently of variation in a power supply voltage, by a method wherein a signal proportinal to the square of a voltage is averaged in DC form, and electrification is effected through comparision of the mean value with a specified comparison voltage. CONSTITUTION:When square wave intermittent electrical connection is made on a glow plug, a power PON during electrical connection is proportional to the square of a voltage VON during electrical connection, and thereby the mean power equivalent to an intermittent period is made uniform even if the VON is varied. Thereby, a voltage proprtional to the square of the VON is produced that the average of a time equivalent to an intermittent period is found and the mean value Vm is made uniform independently on the VON. For this purpose, by means of a circuit consisting of a Zener diode 30 and a resistor 31, a source voltage is controlled so that it is set to approximate square within a practical range, and based on the value, switching is effected. This produces an approximately constant effective voltage, and causes the temperature of a glow plug to be made approximately constant independently of a source voltage.

Abstract: PROBLEM TO BE SOLVED: To improve the ultimate vacuum and prolong the life of a filament via the cyclotron motion by the magnetic field by adding an ion booster pump to a universal high-vacuum pump. SOLUTION: A turbo-molecular pump having the exhaust capability 10<-7> Torr is operated, and a current 50-200A is fed to a filament 1 to cause it to emit thermoelectrons when the degree of vacuum in a vacuum chamber becomes 10<-5> Torr. The electrons are accelerated toward a grid electrode 2 while being applied with the cyclotron motion by the magnetic field generated by a magnet 4. The electrons pass through the lattice-shaped grid electrode 2, are repulsed by a negative-potential ion collector electrode 3, and are captured by the grid electrode 2 after several reciprocating motions. A positive potential in the range of +60V to +120V is applied to the grid electrode 2. Gas molecules are ionized during the reciprocating motions of the electrons.  When a negative potential in the range of -15V to -30V is applied to the ion collector electrode 3, the ionized gas molecules are collected near the ion collector electrode 3 and discharged.

Title: Soldering process
Inventor: MIYAMOTO KEIJI
IPC: H01L21/60
Filed: 1982-11-26
Abstract: PURPOSE:To prevent a Pd decreasing phenomenon in Ag-PD conductor from occuring by a method wherein a reaction layer of silver and tin is formed on a conductor before soldering operation is started. CONSTITUTION:Sn alloy foil and particles with much Sn content is placed on an Ag-Pd conductor 2 inside dams 3 on the surface of the Ag-Pd conductor 2 on a package 1 and then they are heated and melted to separate Ag in the Ag-Pd conductor on Sn layer forming an Ag-Sn reaction layer 7. Next a semiconductor pellet 4 is placed with the bottom up to locate solder bumps 5 on the Ag-Sn reaction layer 7 and then a solder part 6 is formed using Pb rich soldering material to solder the solder bumps 5 by solder part 6 bonding the pellet 4 to the package 1. When the Pb rich soldering material is heated and melted, Pd content in the Ag-Pd conductor is going to enter into semiconductor material but intercepted by the Ag-Sn reaction layer 7 having no influence upon the Ag-Pd content at all. Through these procedures, any corrosion of the conductor 2 may be prevented from occuring.

Abstract: PURPOSE: To close an opening of a fueling hose without inhibiting the movement of the hose from dust, snow and insect by covering the opening for traverse movement of a bottom portion of a fueling hose provided in a case with a bellows assembly which is retractable so that it deforms and moves with a movement of the hose to keep the closed state. CONSTITUTION: Bellows units 31, 31' are provided along a guide rail 22 such that one end thereof is secured to the end of the guide rail 22, and the other end is secured to front and rear ends of a carriage 23 to cover an opening formed between channel members 22a, 22b. When a fuel is supplied, a nozzle pipe 15 is inserted into a fuel inlet of an automobile. Because the carriage 23 laterally moves along the guide rail 22, a coupling 20 also moves, whereby a fueling area becomes elliptic so that the fueling area can be enlarged. When a hose 18 and the coupling 20 move, one bellows 31 shrinks, whereas the other bellows 31' expands with the movement of carriage 23 so that the opening is always closed without inhibiting the movement of the carriage 23.  Accordingly, it is possible to prevent dusts or insects gathering around a night lighting unit 30 from entrance into a case 4 by means of a portion of the bellows 31.

Abstract: PURPOSE:To enable high-efficiency processing even if an analyzing element for end point measurement and analyzing element for rate measurement are randomly disposed by providing a holding means, etc., capable of arranging said analyzing elements in arbitrary sequence. CONSTITUTION:The analyzing element 2 for BUN measurement to be subjected to photometric processing in accordance with an end point method BUN upon lapse of the specified time after dropping of a sample and the analyzing element 2 for GPT measurement to be subjected to photometric processing in accordance with a rate method (GPT) are arranged in arbitrary sequence to a disk 33. A memory means stores either of the methods to which either of the elements 2 conforms. A time management means manages the time necessary for the respective elements 2 to make photometric processing in a photometric part 6 after the sample is dropped in a sample dropping part 12.
