Title: Bar code reader
Inventor: KURASHIMA MINORU
IPC: G06K7/10
Filed: 1995-07-07
Abstract: PROBLEM TO BE SOLVED: To provide a bar code reader which can easily read even such bar codes that are printed on the soft materials like the paper and vinyl sheets, etc., by providing an air suction port at a point near an optical scanning opening part of the reader. SOLUTION: An optical scanning opening part 4 is prepared at a head part 3 of a reading part 1 of a bar code reader and scans the light to read a bar code, i.e., a reading object that is put in front of the part 4. An air suction port 5 is formed at one of both ends of the part 4, and a cock is provided on a tube which is connected to the port 5 at one of its both ends and also connected to a compact vacuum pump at the other end. Then the cock is opened when a push-button switch 6 provided at the side part of a knob 2 of the part 1 is pushed. When a bar code printed on a material having the recessing/ projecting parts like paper, etc., is read, the bar code reader is pressed onto the bar code part and the switch 6 is pushed. Thus the reading object is sucked into the port 5 and the other end of the object is pulled by a hand.  As a result, the recessing/projecting parts of the bar code are eliminated and the bar code can be accurately read.

Title: Semiconductor integrated circuit for audio amplification
Inventor: KINOSHITA HITOSHI
IPC: H01L27/02
Filed: 1987-07-10
Abstract: PURPOSE:To improve the distortion rate characteristic and oscillation stability by making the ground wirings on an IC substrate independent in the first-stage amplifier section, the output amplifier section and other circuit sections, respectively, thereby minimizing the inter-circuit effect. CONSTITUTION:The ground wirings of an IC are divided into the input circuit side including the first-stage amplifier section on the IC substrate and the output amplifier section, and the ground wirings at the input circuit side are divided into a first ground wiring 2 connected only to the first-stage amplifier section 1 and a second ground wiring 5 connected to other small signal system circuit section 3 and a subextraction circuit section 4 at the input circuit side. The first ground wiring 2 and the second ground wiring 5 are respectively connected to different ground pads 6, 7, and commonly connected to one lead frame 10 via bonding wires 8, 9. Since the ground wiring 2 connected to the first-stage amplifier section 1 and the ground wiring 5 are isolated, the ground of the first-stage amplifier section 1 does not rise because of the current of the small signal system circuit section 3 and the voltage drop related to the subextraction circuit 4.

Title: Wafer conveyer
Inventor: NISHIHARA HIDEO
IPC: H01L21/68
Filed: 1996-07-02
Abstract: PROBLEM TO BE SOLVED: To provide a wafer conveyer capable of cleaning contact support members and support block separately. SOLUTION: The conveyer mounts wafers 9 on a support means composed of contact support members for contacting and supporting the wafers 9 and support block 22 which removably fixes the wafer support members 9 through leaf springs 23 having holes at mid-sections. The support block 22 has grooves G. The upper portion of the side face G5 of each groove G is inclined to the support member 21. The leaf spring 23 is fitted into the groove G in the form of an upward convex so that the top end of the support member 21 protrudes from the center opening of the spring 23 to thereby removably fix the support member 21. This allows the support members 21 to be separated from the support block 22 whereby they can be washed in suited conditions to the working conditions and material and the maintenance cost of the conveyer can be reduced.

Title: Optical fiber gyro
Inventor: NISHIWAKI YOSHIAKI
IPC: G01C19/72
Filed: 1982-10-01
Abstract: PURPOSE:To obtain a highly reliably small optical fiber gyro hard to age which is capable of measuring the angular velocity of rotation accurately by providing two subglass blocks between the main glass blocks, a lens and an optical fiber. CONSTITUTION:Light returned from an optical fiber loop 14 is partly taken out with second and third beam splitters 8 and 11 in subglass blocks B and C. When the amplitude intensity of the lights are E'l and E'r, they are proportional to the intensities of CCW light and CW light. As the transmittance and reflectance of the second and third beam splitters 8 and 11 are fixed, the intensity of light can be determined from the values E'l and E'r. In addition, the splitters 8 and 11 can be replaced with polarization beam splitters. This makes the clockwise light and the counterclockwise light the same in the direction of the polarization thereby improving S/N. As a result, a small and light optical fiber gyro can be constructed which is capable of measuring the angular velocity of the rotation accurately.

Abstract: PURPOSE:To obtain a transmission type screen in which a difference in luminance is small, and a shift of a white balance due to a place to be located when it is seen from the front is small, by placing obliquely said screen against a projected luminous flux. CONSTITUTION:A light beam which has been made incident on a first face 25 of a prism element 21 from a point light source placed on a reference object point 24 is refracted and transmits through the first face 25, brought to total reflection by a second face 26 and its advance direction is changed in the forward direction, emitted from the first light-transmissible plate 19, and made incident on a Fresnel lens element 22 of a second light-transmissible plate 20. This transmission type screen makes a cabinet very compact by placing it obliquely against a projected luminous flux, and also, converts a projected luminous flux which is made incident from the oblique direction, to an almost parallel luminous flux by the prism element 21 and the Fresnel lens 22, so that the directivity direction of an emitted light beam emitted from an arbitrary position becomes roughly parallel to the center axis, therefore, a difference in luminance due to the place of the whole screen is small, and a shift of a white balance due to a place when the screen has been seen from the front can also be made small.
