Filed: 1990-06-01
Abstract: PURPOSE:To easily prevent the clogging of nozzles by freely vertically movably providing a diluting liquid tank at the stroke at which the diluting liquid housed therein can be raised from the spraying ports of the nozzles to an upper side from a lower side. CONSTITUTION:Since a work 15 is small in the width size, a width adjusting frame 33 is shifted to a stationary frame 34 side and the shielding plate 29 integral with this width adjusting frame 33 is also moved up to the left nozzle 14a. The upper half of the spraying port 26 of the left nozzle 14a is covered by this shielding plate 29. The flux mists 51a sprayed from this spraying port 29 are shielded by the shielding plate 29 and are recovered without being diffused. On the other hand, the flux mists 51 which are sprayed without being shielded by this shielding plate 29 are limited in the spraying range by an ambient gate 29 are limited in the spraying range by an ambient gate plate 41 and the flux mists leaking from the spacing between the work 15 and the gate plate 41 are sucked into a mist suction slit 44 of a flux mist suction pipe 42 and are thereby recovered.

Title: Underground parking lot and constructing method thereof
Inventor: KANEKO KENICHI
IPC: E21D13/00
Filed: 1992-05-11
Abstract: PURPOSE:To enable construction even in a narrow space. CONSTITUTION:A U-shape tunnel 1 is formed into a ground, a merry-go- round-like parking space system 2 connecting the inside of the U-shaped tunnel 1 and a ground section is arranged annularly, and doorways 3 are installed to the opening sections 4 of the tunnel. Consequently, since one car is moved in the U-shaped tunnel, the sectional area of the tunnel can be reduced, and the thickness of a wall surface can be thinned, thus allowing construction even when the ground area of a parking space is small. Since the tunnel is excavated by a shielding machine, execution is enabled even when there is an obstruction on the ground section.

Title: Method for forming bar-like resin hardened body
Inventor: HARA KOICHIRO
IPC: B29L23/00
Filed: 1988-06-10
Abstract: PURPOSE:To obtain a formed body, the forming accuracy of which is favorable, with high production efficiency without using metal mold by a method wherein a tube having a certain fixed inner diameter in continuous form is formed out of heat resistant, non-plastic, non-metallic and flexible sheet-like material and, after one end being closed by a plug, poured and filled with liquid resin stock. CONSTITUTION:A tubular body formed out of sheet-like material, which is heat resistant to the softening and curing treatment temperatures and non- plastic, is used. For example, a general purpose paper tube 1 made of waste paper, to one end of which a plug 2 is fitted, is prepared, heated, dried and preheated. Resin mixture 3 consisting of thermosetting polyurethane, prepolymer and hardener is poured and filled in the vertically supported paper tube and, after that, postcured by heating in order to form a bar-like resin body. Since breakable substance is used as the forming mold, demolding is done only by breaking the mold for removing the body. The bar-like body can be formed without using releasant at all, resulting in allowing to bring the development of defective item due to releasant to nil.

Title: Optical scale
Inventor: IGAKI MASAHIKO
IPC: G06K7/01
Filed: 1985-07-01
Abstract: PURPOSE:To prepare an optical scale of high resolution in a simple manner and at low cost by a method wherein a light-transmitting portion and a non-light-transmitting portion formed by a slanting surface having an incident angle set to be larger than a critical angle are formed alternately on the surface of a light-transmitting material. CONSTITUTION:A light-transmitting portion 9 and a non-light-transmitting portion 10 are formed alternately at the same pitch in a mark part of the circumference side of the lower surface of a disk-type optical scale 3. On the occasion, the transmitting portion 0 is formed to be a flat surface, while the non-transmitting portion 10 is formed to be a slanting surface whereon incident light L2 forms an incident angle of 45 degree which is larger than a critical angle. A fixed optical lattice 4 disposed below the scale 3 is formed of the same material and in the same shape as the scale 3, and light passes therethrough when the phases of indentations of the two accord with each other, while it returns onto the incidence side through two total reflections and does not reach a light-receiving element 5 when said phases are slided from each other by a half cycle. Polymethyl methacrylate is used for the two, and therefore the scale having a resolution of high precision can be prepared simply by a molding die.

Title: Screen for liquid crystal projector
Inventor: TAKAYAMA SHIGEHIKO
IPC: G03H1/26
Filed: 1994-06-27
Abstract: PURPOSE:To provide a screen for a liquid crystal projector constituted so that a picture projected by the light of a liquid crystal projector can be recognized in the light. CONSTITUTION:This is the screen used for the color liquid crystal projector projecting the picture on liquid crystal by transmitting or reflecting light from a light source through/on the liquid crystal. Then, Lippmann holograms (BS, GS and RS) having high reflectivity only with respect to the wavelength band of the light emitted from the liquid crystal projector are formed on the screen. Therefore, since almost only the light emitted from the liquid crystal projector is reflected on the screen and the light of the other wavelength band is absorbed, the reflection of external light is suppressed to the utmost and the picture by the liquid crystal projector which can be recognized in the light is obtained.

Abstract: PURPOSE:To properly judge the change in physical condition, by discriminating whether the left end of a displayed graph corresponds to a menstruation start day, on the basis of the display of a month marker when an menstrual cycle exceeds a graph display range. CONSTITUTION:An electronic type recording clinical thermometer apparatus is limited to about 34 days in the display of one menstrual cycle in order to omit a display part or the like as possible and to achieve wt. reduction and miniaturization. In a menstrual cycle exceeding about 34 days, data can not displayed at once. In such a case that basal body temp. is displayed by a graph, when the left end of display is menstruation start day, a month marker puts on and off to show that the left end of a graph is not the menstruation day to call attention. A month marker flash memory circuit 22 has memory such that the month marker flashes or does not flash at every month and a month marker flash control circuit 24 allows the month marker to put on and off or flash according thereto. By the mentioned constitution, even when the menstruation cycle exceeds a display possible range, the menstruation start day can be made clear.
