Title: Flat package for electronic part
Inventor: HARA SHOJI
IPC: H01L23/28
Filed: 1986-01-28
Abstract: PURPOSE:To prevent a lead from getting into touch with the frame wall of a tray and to improve the reliability of work by loosely fitting a non-circular recessed section formed in the lower surface of a resin sealing section of an electronic part to a projection shaped on the tray. CONSTITUTION:A rectangular recessed section 4 is formed to the lower surface of a resin sealing section 1. A rectangular projection 5, to which the recessed section 4 is fitted loosely, is formed at approximately the center of the recessed section surrounded by a frame 3a in a tray 3. The recessed section 4 of the sealing section 1 is inserted to the projection 5 of the tray 3, thus preventing movement and revolution. Consequently, leads 2 are not made to get into touch with the wall of the frame 3a, thus eliminating deformation during transportation. Accordingly, the reliability of work is improved largely.

Title: Data transmitter/receiver
Inventor: IWATSUJI ICHIRO
IPC: H04L25/49
Filed: 1987-01-27
Abstract: PURPOSE:To prevent transmission data from being disturbed in a transmission system amd to avoid a transmission impossibility by providing a scramble circuit for transforming the transmission data to a pulse train of a duty ratio of 50 % and inputting to a driver. CONSTITUTION:In the case of an input signal VIN shown by dotted lines, the pulse is not faded away but normally transmitted to an output VOUT. The input signal VIN shown by the dotted lines has the apparent duty ratio of 50 % of the pulse and it is required not to tear away a voltage between transmission lines in the drawing to -5V or +5V. Namely, since a transition duration t(TR) in the transmission system is finite, the duty of the data may be set to 50 % in order to feed the data having the same maximum frequency farther. Accordingly, the scramble circuit 9 transforms the transmission data to the pulse train of the duty ratio of 50 % and inputs to the driver D. Thereby, an average voltage between the transmission lines can be set to the state near to OV and even at the time of a long transmission system, the transmission data can be effectively transmitted.

Title: Excellently familiar housing structure between artificial turf laying surface and boundary wall
Inventor: FURUKAWA TORU
IPC: E01C13/08
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To reduce a burden to both a building and artificial turf, and to easily/efficiently adjust extension/contraction by tearing off the tip edge part of an under pad part of the artificial turf by a proper range, and windingly drawing the surface layer part according to a boundary wall surface. SOLUTION: Artificial turf 4 is laid so as to be housed in a thickness range of a fence cushion 8 of a boundary wall 1 by windingly drawing the remaining surface layer part 4a by tearing off about 10 to 15 cm of the tip edge part butted against the boundary wall 1 of the under pad part 4b. Since there is no need to arrange a lateral slit or to form a digging ditch by digging the floor surface 3 of the boundary wall 1, execution work can be easily performed without imposing a burden at all on a building. Since extension/contraction can be sufficiently absorbed besides an artificial turf 4 side burden is little, labor of extension/contraction adjusting maintenance can be sharply reduced without causing a problem at all in play.

Filed: 1989-01-25
Abstract: PURPOSE:To reduce the vibration of a motor itself by forming a part constituting a motor yoke from a damping steel plate. CONSTITUTION:The rotor 2 of a motor 1 is composed of a rotating shaft 3 and a core 4 and coil 5, and said coil 5 is wound around said core 4.

Title: Method and reagent for determining leucine aminopeptidase activity
Inventor: YOKOJIMA TETSUYOSHI
IPC: C12Q1/37
Filed: 1980-02-14
Abstract: PURPOSE: To determine the activity of leucine aminopeptidase (LAP) in a biospecimen, rapidly, easily and accurately, by using a L-leucyl-4-N,N-dialkylaminoanilide derivative which is a novel substrate, or its salt.  
     CONSTITUTION: A novel substrate of formula (R 1  and R 2  are lower alkyl), e.g. L-leucyl-3-carboxy-4-N,N-dimethylaminoanilide, is converted by the enzymatic action of LAP to 2-dialkylamino-5-aminobenzoic acid, which is converted to a colored compound by the oxidative condensation with a proper coupler and subjected to colorimetry to determine the LAP activity. High solubility of the substrate in water enables easy preparation of the substrate solution. The reproducibility of the determination is good because of small variation of the color with temperature and time.

Filed: 1984-01-31
Abstract: PURPOSE:To surely shut off the supply of fuel when an earthquake or the like occures, by providing such an arrangement that a weight is moved in association with oscillation to release a fixing hardware. CONSTITUTION:A weight 2 which is liable to move lifts up a fixing hardware 3 away from a notch in a fixing cam 4. The cam 4 released from its fixed condition rotates a cock 6 under the force of a spring 5 to shut off a fuel passage. In order to reuse the cock a reset lever is rotated in the direction opposite to the operating direction to check the fixing hardware into the notch in the cam 4 which is therefore locked.

Title: Method and equipment for preparing aqueous slaked lime solution
Inventor: KOJIMA SADAO
IPC: C01F11/02
Filed: 1979-02-16
Abstract: PURPOSE: To effect continuous, long-period supply of a saturated aqueous solution of slaked lime useful for pH adjustment of tap water by a method wherein the lower section of a tank is divided into upper and lower sections by partition plate provided with annular metal net, and agitation blade installed in slaked lime stack layer is slowly rotated.  
     CONSTITUTION: The slaked lime reservoir and dissolving tank 1 is charged with water. From an inlet 7 of the tank 1, slaked lime is charged to form stack layer of slaked lime on top of a partition plate 2. At 1W2hr. after slaked lime has been charged and settled, water is charged through a water inlet 5, an agitation blade 3 is slowly rotated so that a solution saturated with slaked lime is obtained. At this time, water flow rate and agitation are adjusted so that the level of fluidizing layer 8 of slaked lime (area enclosed by chain line) goes not too high. In order to avoid solid particles of slaked lime from being present in saturated slaked lime solution, a high height of the fluidizing layer 8 requires a high height of the tank 1. This is not desirable. In this manner, the saturated slaked lime solution is continuously provided through the outlet 6 until all slaked lime in the tank is consumed without reducing concentration of slaked lime.
