Title: Stationary type scanner system
Inventor: KOBAYASHI MASAYUKI
IPC: G06K7/10
Filed: 1991-05-27
Abstract: PURPOSE:To easily position a bar code by reading the bar code sticked on the topside of a product by means of reflecting irradiation light from a device main body with a half mirror. CONSTITUTION:The main body 1 is provided with a half mirror 4 turning irradiation light from underside into irradiation light from upside so that an operator can see the bar code sticked on the product 2. The bar code is read by reflecting the irradiation light emitted from the main body 1 with the half mirror 4 with the bar code 3 on the product 2 facing up. Consequently, as the bar code can be read with the bar code face facing up, unnecessary work which changes the direction of the bar code face to under side is omitted. Besides, as the operator can see the bar code stuck on the product through the half mirror. the bar code can easily be positioned.

Title: Horn speaker
Inventor: YOSHIOKA TSUTOMU
IPC: H04R1/30
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To control a sound pressure level (polar pattern) in every loudspeaking direction. SOLUTION: A sound outputted from a speaker driver 2 is fed to a horn 4 formed to be nearly flat through a sound guide pipe 3 and the sound is sounded from an opening 45 of the horn 4. Moreover, the sound guide 3 is coupled with an upper face of the horn 4 and the shape of the coupled part is formed to be a slender rectangle. Thus, it is equivalent to it that a straight line sound source, that is, a linear sound source is formed as a sound supply source to the horn 4. In this state, the loudspeaking distribution of sound emitted from the linear sound source, that is, the directivity is changed by changing the coupling position and the coupling angle or the like of the sound guide 3 with respect to the horn 4.

Title: Braun tube
Inventor: FUKUZAWA KENICHI
IPC: H01J29/87
Filed: 1981-08-03
Abstract: PURPOSE:To obtain a p-Th-type Braun tube or the like the end surface of which can be made to appear dark by covering the front end surface of a metal band, which is attached around the outer surface of a panel, with a tap having a dark color. CONSTITUTION:A tape 2 is wrapped around the outer side wall of a panel 1 of a valve, and a metal band 3 is attached over the tape 2 so as to make the front end surface of the band 3 to be covered with an expanded end 2a of the tape 2. The tape 2 realizes an adhesion between the valve and the band 3, and also alleviates thermal shocks which are given to the valve by the metal band 3 heated to high temperature during shrink fit work. Since the tape 2 is prepared from a heat foaming matter, which contains a black paint having a property of foaming and becoming thick by heating, the front end of the metal band 3 can be covered with the black tape 2 at the same time when the metal band 3 is subjected to the shrink fit.

Title: Light-transmission decoration having uneven cut surface and manufacture thereof
Inventor: ITO MASAKI
IPC: B32B7/02
Filed: 1993-04-23
Abstract: PURPOSE:To obtain a light-transmission decoration with an excellent appearance and manufacture it effectively by disposing a stationary mold and a movable mold to form as a primary molding, and molding integrally contour parts in use of transparent synthetic resin materials in a manner allowing a projected figure to leave. CONSTITUTION:By primary molding, a base B1 is molded with an opaque material. Next, secondary molding is executed to molded decorative plates 1 with a transparent material on contour parts in a state of leaving a projected part (d). Various representations can be achieved by changing the coloring of materials for forming the base B1. A three-layer constitution can also be available by providing an intermediate layer 1' during the secondary molding, i.e., the colors of the base B1 and projected figure (d) are changed by the use of a three color molding machine in order to enable it to be molded effectively. Also, the projected figure (d') can be formed in a manner permitting it to further project from the entire surface. As a consequence of this process, places for heat caulking and adhering means are eliminated, resulting in improvement of the appearances.

Title: Reacting device for gas treatment by electron beam
Inventor: SAKAMOTO ISAMU
IPC: G21K5/08
Filed: 1994-04-21
Abstract: PURPOSE:To avoid the loss of electron, and efficiently utilize the incident electron by arranging magnets on the outer circumference of a reacting vessel in such a manner that the magnetic poles of the adjacent magnets are mutually differed in polarity to form a cusp magnetic field. CONSTITUTION:As a reacting vessel 2, a one having a diameter shorter than the range for extinguishing all the energies of accelerated electrons is selected. A plurality of bar magnets 5 extended in the longitudinal direction of the vessel 2 are arranged on the outer circumference of the reacting vessel 2 along the circumferential direction in such a manner that the magnetic poles directing the wall surface of the vessel 2 of the mutually adjacent magnets 5 are mutually differed in polarity. A magnetic flux 6 is passed between the adjacent magnets to form a cusp magnetic field. Thus, the flying direction of the electrons is reversed to return the electrons into the reactor 2, the collision of the electrons with the inner wall of the vessel 2 is avoided, and the wasteful loss of the electron energy is thus avoided.

Abstract: PROBLEM TO BE SOLVED: To provide a plumb hob-type pressure gage in which the measuring range of a pressure is sufficiently wide and by which a high pressure and a low pressure can be measured quickly. SOLUTION: When a pressure P is applied through a hole 12a in a pressure introduction part 12, a first ram part 2 and a second ram part 3 are raised and lowered at a first raising and lowering stroke.
