Title: Slide
Inventor: ISE TSUTOMU
IPC: A63G21/18
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To provide a slide used at the waterside or on the water and excellent in the amusing property by rockably supporting a fitting section between the slide and an erect stand, fitting a float on the lower side of the tip section of the slide, and floating it on the water. SOLUTION: The fitting portion 3 between the slide 1 and erect stand 2 of a slide facility installed at the water side such as the pool side or a beach is formed into a rockable driven shaft, and a float 5 is fitted on the lower side of the tip section 4 of the slide 1. The float 5 has such buoyancy that its tip section 4 is exposed on the water surface when no person rides on it and the tip section 4 is made flush with the water surface when a person with the body weight of about 50 kg rides on it. When this slide facility is installed at the beach or a wave making pool, the slide 1 not only follows the vertical change of the water level caused by the ebb and flow of tide but also is vertically moved by waves, and a user sliding down from above can enjoy different lively feeling unavailable by a normal slide.

Title: Digital audio disk reproducer
Inventor: ISHIBASHI MICHIYASU
IPC: G11B19/28
Filed: 1983-07-26
Abstract: PURPOSE:To attain the reproduction of a disk just by loading it by performing an automatic switch to a prescribed revolving speed of the disk after detecting a channel number display signal out of a control signal to judge a prescribed channel number. CONSTITUTION:The channels 2 and 4 are judged and displayed when the first bit of a control signal is ''0'' and ''1'', respectively. When a disk of the channel 2 is judged by the control signal, the outputs of terminals 12a and 12c are set at H levels and then set at L levels if a disk of the channel 4 is judged. When the 4- channel disk is loaded, the levels of terminals 12a and 12c are changed to L from H. Therefore switches S1-S3 are changed to the channel 4 from the channel 2. As a result, the disk undergoes the phase control at the linear speed of the channel 4 and the audio signal of the channel 4 is reproduced. Thus the reproduction is possible just by loading a disk without confirmation and switching performed by a user each time.

IPC: H01L23/50
Filed: 1981-08-31
Abstract: PURPOSE:To obtain uniform dust flow resistance to the surface of a substrate by a method wherein dummy parts are fitted to the both sides of an element substrate when resin coating is carried out by the flow dipping method, or projections are provided at the upper ends of both sides of a substrate. CONSTITUTION:An integrated circuit formed on the surface of a substrate 2 are formed by patterning at the central part of the substrate, and externally mounted elements such as semiconductor IC, chip components, etc. that are mounted on the substrate are also, in most cases, provided closely to the central part. Thus, the flow resistance of epoxy dust that flows by compressed air is smaller at the both sides than the central part of the substrate, and this causes a coated film to rise. There are two methods which make flow resistance uniform to prevent the above phenomenon. One is a method wherein dummy parts 7 are fitted to the both sides of the element substrate 2. The other is a method wherein a substrate having projections 8 at the upper ends of both sides of the substrate 2 is used.
