Title: Electronic parts mounting method and electronic parts mounting board
Inventor: SUZUKI HIDEAKI
IPC: H05K3/34
Filed: 1991-03-27
Abstract: PURPOSE:To correspond with a thinned board for electronic parts mounting, and facilitate the exchange of small-sized integrated parts, by forming a hole having the same shape as the electronic parts to be mounted, in the printed wiring board, and engaging the parts with the hole. CONSTITUTION:At a small-sized integrated parts mounting portion of a printed wiring board 11, a hole 12 having the same shape as a small-sized integrated part 4 is bored. Around the hole 12, a pattern 13 for terminal connection of the small-sized integrated part 4 is formed. Cream solder is printed on the printed wiring board 11 by using a screen. Surface mount type electronic parts 5, 6 are machine-mounted. The small-sized integrated parts 4 is fitted in the hole 12 by a mounting equipment. The small-sized integrated parts 4 is exchanged in the following way; the solder connection part of the small-sized integrated parts 4 of an electronic parts mounting board 14 is locally heated, and solder is turned into a melted state, thereby extracting the small-sized integrated parts 4. After extraction, cream solder is spread on the connection pattern 13 of the printed wiring board 11, and another small-sized integrated parts 4 is inserted into the hole 12.

Title: Carbon rod for dry cell
Inventor: IWAMARU FUTAYASU
IPC: H01M4/75
Filed: 1981-06-08
Abstract: PURPOSE:To provide a carbon rod of high density for a dry cell, by adding a prescribed quantity of thermoplastic resin to carbon and a binder to prepare a material to mold the carbon rod and by baking the molded rod. CONSTITUTION:Carbon such as graphite and a binder such as pitch are mixed with 1-10wt% of thermoplastic resin such as polystyrene and polyethylene to prepare a material to mold a carbon rod. The material is polyethylene to prepare a material to mold a carbon rod. The material is molded under pressure and then shaped as a rod. The rod-shaped material is baked under inert gas, thereby manufacturing the carbon rod for a dry cell. Since ther thermoplastic resin has a higher filling property than the binder and the change in the viscosity of the thermoplastic resin at the molding temperature is little, the molding property is greatly improved. Since the thermoplastic resin is partly carbonized in the baking, the density of the carbon rod is made very high.

Title: Preparation of gallium nitride single crystal
Inventor: YOSHIDA KIYOTERU
IPC: C30B29/38
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To prepare a high-quality single crystal having a large caliber by successively growing a GaN buffer layer and a GaN single crystal layer on a semiconductor substrate having a lower melting point than that of GaN, heating the substrate and then removing the substrate by chemical etching. SOLUTION: A GaAs substrate 1 of a group III to V compound having a lower melting point than that of GaN is conveyed to a growth chamber. The surface of the subtrate 1 is then irradiated with a Ga flux in the growth chamber to form a group III element film of Ga on the surface of the substrate 1 in the growth chamber and then exposed to dimethylhydrazine which is a raw material gas for a nitrogen source to form a GaN buffer layer 2 having about 300 Å film thickness. The nitrogen source is then changed for ammonia to form a GaN single crystal 3 of a thick film. The substrate temperature is subsequently raised to about 1,000 deg.C in an ammonia atmosphere and kept in this state for about 5 min to dissociate As from the GaAs substrate 1 and thermally degrade the GaAs substrate 1. After cooling, chemical etching of the substrate 1 is carried out.  Since the joining area 1a is roughened, the GaAs substrate 1 is peeled from the GaN buffer layer 2 and removed to prepare the GaN single crystal 3.

Title: Antirolling ship
Inventor: KITANAKA KATSUMI
IPC: B63B29/02
Filed: 1988-04-12
Abstract: PURPOSE:To aim at the facilitation of manufacture and antirolling at the time of low speed navigation by flowing a cabin in a liquid tank installed in the hull. CONSTITUTION:A hull 2 and a cabin 3 are separated from each other and formed separately, and a pool-form void space 4 capable of fitting the cabin 3 loosely in this hull 2 is being installed. A liquid 5 is stored in this void space 4, and the cabin 3 is floatable. The hull 2 and the cabin 3 are connected to each other shiftably to some extent. Consequently, even if pitching and rolling occur in the hull 2, the liquid 5 in the void space 4 tries to keep a horizontal surface, so that the pitching and rolling of the cabin 3 are absorbed more than that of the hull 2. In this connection, this ship is relatively inexpensive and, what is more, manufacture is also easy enough.

Title: Water level measuring system
Inventor: YAGIHASHI YOSHIO
IPC: G01F23/00
Filed: 1994-04-26
Abstract: PURPOSE:To achieve prevention of failure in measurement because of a trouble or the like by monitoring a water level constantly based on a water level doubled to select the water level decided to be correct by a certain fixed algorithm. CONSTITUTION:Water level meters 11 and 12 are set at a specified location where a water level is to be measured to detect a water level constantly. Detection data are converted to BCD codes to be inputted into an automatic water level selector 20, which 20 determines any one of the water levels to be correct by a judgment according to a fixed algorithm based on the two water level data taken. For example, a checking is made to spot an instantaneous input data error, such as parity error, errors other than that of BCD, abnormality in a counter part converter and the like. When any error is found and if the data from the water level meter 11 is normal while the data from the water level meter 12 is abnormal, the automatic water level selector 20 selects the instantaneous input data from the water level meter 11.

Abstract: PROBLEM TO BE SOLVED: To execute a hydraulic bulging causing little reduction of the thickness at the outside part of a curving part by arranging a bulging range at a part corresponding to the inside of a bending part of a blank in a cavity, supplying a pressure medium into the inner part of the blank and plastic-deforming the blank into the inside of the binding part. SOLUTION: A bending tube 1 is set to the cavity 20 and fixed by closing an upper die 2 and a lower die 3. The pressure medium is supplied into the inner part of the bending tube 1 set in the cavity 20 through a pressure hose 9 and a pressure medium supplying hole 11 and the inner pressure is given to the bending tube 1 to apply the bulging to the bending tube 1. The bulging range 4 is formed to the part corresponding to the inside of the bending part of the blank in the cavity 20, and since only the inside part having thick thickness is positively bulged, it can be avoided that the outside part having thin thickness is further thinned by the bulging.

IPC: G06K7/10
Filed: 1992-04-09
Abstract: PURPOSE:To provide a code reader improved so that collimation to a code can be accurately executed even by an operator with low skillness. CONSTITUTION:The code reader is provided with a laser diode 4 for generating a red beam, mirrors 7, 8, 17, 18 and cylinder lenses 9, 10, 19, 20 for converting the red beam into four face beams parallel with a code reading optical axis A and having four square face beams and mirrors 21, 22 for converting the red beam into two linear beams intersecting at a position separated by a prescribed distance.
