IPC: B60Q1/26
Filed: 1997-02-12
Abstract: PROBLEM TO BE SOLVED: To enlarge the irradiative range of light, prevent the light from leaking to an adjacent lighting device and improve external view. SOLUTION: A diffusion curved face 6 to diffuse and irradiate externally and widely a light L from a light source bulb 50 is set in the inside of a connective part between the light irradiation part 30A of a lens 3A and a sealed leg part 31A. By this diffusion curved face 6, the light L from the light source bulb 50 can be diffused and radiated more widely than the irradiative range by the light irradiation part 30A. Since the part of the lens 3A that enters from the round is a more projected shape at the outside than a linear ridge line 60, the curvature radius of the diffusion curved face 6 can be made large so that the light L can be diffused and irradiated vary widely.  When plural lighting device are adjacent to each other, leakage that occurs by the light projected to the lens 2 of the adjacent lighting device can be prevented because the light L incident on the diffusion curved face 6 is externally diffused and irradiated. Nice looking is obtained because a group of light control element 32A and the diffusion curved face 6 and smoothly connected without difference in level at its interval.

Filed: 1988-02-08
Abstract: PURPOSE:To realize the execution of arithmetic in the depth frequency of a binary tree to an equation including (m) pieces of arithmetic by performing (n) pieces of logical arithmetic to the data on the 2n-bit width of a result holding register based on a control signal and transferring the data on the n-bit width obtained as the result of said logical arithmetic to the lower (n) bits of the result holding register. CONSTITUTION:An arithmetic logic unit 5 transfers the value corresponding to the leave of a binary tree to a result holding register 3 via a 2-input/1-output multiplexer 2 under the control of a microprogram. Then a parallel logic computing element 4 performs (n) pieces of logic arithmetic designated by a microinstruction to the 2n-bit data stored in the register 3. The results of these logic arithmetic are stored in the lower (n) bits of the register 3. This means that the arithmetic operations which are equidistant from the root of the binary tree are carried out at one time within a single microinstruction. As a result, the arithmetic operation is possible to an equation including (m) pieces of arithmetic in the frequency of depth (logm in the best case) of the binary tree.

Inventor: KISHINO MASARU
IPC: G01J3/02
Filed: 1986-02-12
Abstract: PURPOSE:To obtain a light spectrum analyzer which is based on a processing by an electric method, by using an oscillator and an acoustooptical polarizer. CONSTITUTION:A parallel light beam of a light source 1 is made incident into an acoustooptic polarizer 2 while an output of an oscillator 3 is applied thereto for driving. An ultrasonic wave is generated within the polarizer 2 to emit a primary diffraction emission light. The light output is made incident into an optical system 5 through a lens 4. Optical paths of the lens 4, the optical system 5 and a light receiving unit 6 are fixed to match the angle of the primary diffraction light. With such an arrangement, only in the combination which allows the product of a wavelength lambda of the light source 1 and an output frequency f0 of the oscillator 3 to keep a specified refraction angle theta at a fixed value, light of the light source 1 passes through the optical system 5 to be detected with the light receiving unit 6. Thus, the frequency of the oscillator 3 at which the light is detected with the light receiving unit 6 is found by sweeping an output frequency f0 of the oscillator 3 in a range of f0+ or -DELTAf thereby enabling reading of the wavelength of the light source 1.

Abstract: PURPOSE:To prevent generation of an anormalous sound and to enhance strength of the rear wall of a main body by vertically providing a boss between a fan in the swirl chamber of an air cleaner and an exhaust port and changing the air flow in the swirl chamber. CONSTITUTION:An air cleaner consists of both the front part of a main body having a filter and the rear part thereof having a fan 8.
