Title: Thermal head driving device
Inventor: HAMAMURA AKIHIKO
IPC: B41J2/355
Filed: 1985-11-05
Abstract: PURPOSE:To enable the density distribution in a dot to be uniform, by supplying a first energizing pulse to rapidly raise the surface temperature of a resistance heat generating element, and supplying second energizing pulses consisting of a plurality of pulses having a small pulse width. CONSTITUTION:With a printing timing pulse given in synchronism with a recording paper feeding operation, a first pulse generating circuit 2 generates a first energizing pulse P1 with a pulse width tau1, whereby the surface temperature of a resistance heat generating element is rapidly raised, reaching a predetermined temperature corresponding to a printed density after the lapse of time of tau1. When the generation of the first energizing pulse P1 is completed, ON- OFF pulses with a fixed pulse width tau3 are generated with a repetition period T3 determined by the printed density, and the output of a second energizing pulse P2 is repeatedly generated until a preset printing time tau0 elapses. since the heat generating temperature corresponding to the printed density which is obtained by the first energizing pulse P1 is thus maintained, the density distribution in a dot can be maintained to be uniform.

Title: Laser welding method
Inventor: OMI YOSHINORI
IPC: B23K26/32
Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To weld a hardly welding material with a laser beam without a welding crack by regulating the oxygen gas content of an assist gas in a specific value and controlling the bead width and the welding width of a welding part in a specific range. SOLUTION: In a laser beam welding of a material known conventionally as a hardly welding material among iron, carbon steel and stainless steel, an assist gas is contained with oxygen of 5 to 50 volume %, the remainder is made of Ar, He or an inert gas of N2 , etc., and this gas is made to blow on the irradiation face of the laser beam. In the cross-section of the welding part, the heat carrying direction (the convection direction) is made to the direction from the central lower part toward the outside circumference of the bead, the bead width W and the welding width L are made almost same and the value of W/L is approached to 1. The defective welding (crack) is hardly generated.  When a molten pool 3 is cooled and solidified in the state that the W/L is remarkably large, the shrinkage stress is generated based on the difference of W and L, the crack is generated from nearby the cross-point of the welding face of the metals 1, 2 and the outside circumferential face of the welding part.

Title: Bottom plate movable game medium storage tank
Inventor: NAKAJIMA KEN
IPC: A63F7/02
Filed: 1995-09-01
Abstract: PROBLEM TO BE SOLVED: To store pachinko balls even in a lower part of a gradient of a bottom plate, and easily discharge them by the gradient of the bottom plate by providing the bottom plate to vertically move by weight of thrown-in game medium storage and a vertically moving mechanism to support the bottom plate so as to be vertically movable. SOLUTION: When pachinko balls are flowed in from a throwing-in port 2 of a ball tank 1, one end 15 of a bottom plate 4 is pushed downward by weight of the pachinko balls, and the pachinko balls can be additionally stored by a volume increased quantity by a movement of the bottom plate 4. In the case where they are discharged from a ball outlet 3, when the pachinko balls are almost fully stored, they are pushed out from the ball outlet 3 by pressure by weight of pachinko balls. The pachinko balls are discharged from the ball outlet 3, and when residual pachinko balls reduce, gross weight of the pachinko balls applied to the bottom plate 4 becomes light, and a spring 5 arranged under the bottom plate 4 extends, and since the bottom plate 4 is raised and inclines, the residual balls are smoothly discharged from the ball outlet 3.

Abstract: PURPOSE:To effectively use the internal space of a vacuum container and enable good displaying, by providing a light receiving element on a glass base plate provided with a drive circuit, to receive a signal through the medium of light and reduce the influence of the capacity between wirings. CONSTITUTION:An electric signal such as scanning data from a control section is converted into a light signal by the light emitting diode 31 of a light emitting element block 7.

Title: Transformer
Inventor: TOKUDA KATSUMI
IPC: H02M7/48
Filed: 1990-09-18
Abstract: PURPOSE:To obtain a transformer which has formed a primary-side resonance capacity for the transformer without attaching a capacitor at the outside and which is small-sized and whose heat value is small by a method wherein a metal foil is wound to form a primary winding and the primary-side resonance capacity is formed of an electrostatic capacity between individual windings. CONSTITUTION:At this transformer, a part 4 is a primary winding formed by piling up a metal sheet and an insulating sheet and by winding them to be a cylindrical shape, and a core 3 is inserted in the primary winding. The core 3 is connected to a ground potential. A primary-winding capacity and a capacity between the winding and the core are decided to prescribed values by the area of the metal foil and the permittivity of the insulating sheet or the thickness size of the insulating sheet. At a self-oscillation type converter using the transformer, C1 represents the primary-winding capacity and acts as a primary-side resonance capacity. Cs is a secondary-winding capacity and acts as a secondary-side resonance capacity together with a capacitor Cs' connected at the outside as required. When a composite capacity of Cs and Cs' is designated as C2 and the resistance ratio of a secondary winding to the primary winding for the transformer is designated as (m), it is possible to reduce the copper loss of the transformer to a minimum when C1 is decided so as to obtain the relationship of C1:C2=m:1. As a result, it is possible to constitute the transformer which is small-sized and whose heat value is small.

Title: Amino acid analyzer
Inventor: ISHIDA YASUO
IPC: G01N30/46
Filed: 1983-12-29
Abstract: PURPOSE:To reduce analysis time while eliminating column aging with a high resolution separation of neutral and basic amino acid containing acid amino acid by using two kinds of cation exchange resin columns, Na type and Li type. CONSTITUTION:A sample 3 is injected into a flow of an acid amino acid separating solution 11 to be fed to an Na type cation exchange resin column 4 and after the acid amino acid alone is separated, the mixture is fed to an Li type cation exchange resin column 6. Then, neutral amino acid and basic amino acid separating solutions 12 and 13 are fed to the column 4 subsequently to separate the neutral amino acid and basic amino acid, which are colored and detected with a color formating section 9. Here, the separation of acidic amino acid takes much time but after the separation of the neutral and basic amino acids with the column 4, the acidic amino acid is separated with the column 6 and finally, reaches the color forming section 9 to be detected. This enables an efficient analysis of acidic amino acid such as glutamine and aspartic acid and a number of neutral and basic amino acids thereby reducing the analysis time.
