IPC: G09F13/18
Filed: 1997-02-03
Abstract: PROBLEM TO BE SOLVED: To obtain a kit for construction, handicraft, etc., which emits light from only a pattern part by using a light guide body which easily causes total reflection inside, making light enter into the light guide body, and diffusing it to the outside as irregularly reflected light from a finely uneven part formed in the light guide body so that the uneven part appears to be illuminating. SOLUTION: For the light guide body 1, a resin-made or glass-made transparent plate with a shiny surface is used and on the surface of the light guide body 1, the pattern part 2 is formed of a flaw having fine unevenness. A light source protection material is inserted into a frame 3 and a small light bulbs, etc., which are wired in series so as to suit to the voltage of a power source in use are arranged as a light source 5 in the light source protection material.  When the light of the light source 5 is made incident on the light guide body 1 from its end edge part, the incident light travels in the light guide body 1 through total reflection and never exits from the light guide body except the pattern part 2 and is refracted and reflected only by the fine unevenness of the pattern part 2 of the surface of the light guide body 1 to exit from the light guide body 1 in both the front and rear directions through irregular reflection, so that only the pattern part 2 appears to be shiny.

Abstract: PURPOSE:To obtain a satisfactory output sound pressure response characteristic over a wide band by matching the center of gravity in a symmetrical star weight, which is composed of two parts of a central part and a protruding part, with the center of a piezoelectric vibrating element, interposing a braking piece composed of an elastic layer in an interval between the weight and vibrating element and elastically coupling the both weight and vibrating element. CONSTITUTION:For a weight 4, a back surface is wholly made flat and the center of gravity 9, which is the center of the weight, is matched with a center 1a of a vibrator 1 through a braking piece 7. Then, the weight and vibrator 1 are elastically coupled. For the braking piece 7, a pressure sensitive elastic adhesive agent or an elastic silicone adhesive agent is applied to the both surfaces of the piece, which normally has thickness in the measure of 1mm. Then, one surface is attached to the weight 4 and the, other surface is attached to the vibrator 1 with attention as much as possible so that bend distortion can not be applied. Then, the weight and vibrator are elastically coupled.

Title: Recording head
Inventor: OKI YASUSHI
IPC: B41J2/045
Filed: 1998-02-17
Abstract: PROBLEM TO BE SOLVED: To record an image with high resolution by jetting micro ink drops. SOLUTION: The recording head 10 has a cantilever structure where a resilient member 12 is supported by a vibration generating means 16 at the base end part 14. When the means 16 is vibrated at a specified frequency, the resilient member 12 resonates to jet an ink drop from the vibratory plane in the vicinity of the forward end part 18 thus recording a dot on a recording sheet. Consequently, a high resolution image can be recorded with micro ink drops. The repeating period of driving signal being applied from a signal generating means 20 to the vibration generating means 16 is set equal to an integer times of the period of residual vibration of the means 16 (synchronized) thus suppressing the effect of residual vibration at the vibration generating means 16. According to the structure, period of driving signal can be shortened resulting in high speed image recording.

Abstract: PURPOSE:To limit the increase in tape tension within an allowable range and protect the edge of a magnetic tape from a damage by a method wherein the thickness on the type of the tape is detected and, in accordance with the detected result, the transfer speed of tape loading is controlled. CONSTITUTION:When a tape is thin, a tape thickness detecting hole Tc is provided in the bottom plane of a cassette tape enclosure Tb and, when the tape is thick, it is not provided.

IPC: G02B15/22
Filed: 1981-03-11
Abstract: PURPOSE: To perform focusing with the turning of a control ring as well as the magnification varying operation and the macrooperation with the displacement of an optical axis, by engaging a control ring and a variable magnification optical system via a cam groove including a circular groove formed centering on the optical axis and a spiral groove.  
     CONSTITUTION: With the turning of a control ring 6, a focusing lens L 1  focuses via the engagement of a linear groove 6c and a pin 2a. In this case, a variable magnification lens L 2  has no displacement. The variable magnification is controlled by displacing the ring 6 toward the optical axis. With this displacement, the lens L 2  and a compensating lens L 3  have a displacement, respectively. The focusing state is held while the variable magnification control is carried out. When the ring 6 is turned over the closest position, the lens L 1  has a slight displacement. At the same time, the spiral groove β of the ring 6 pushes a pin 3b of the 2nd holding barrel 3 toward the optical axis. As a result, the lens L 3  has a displacement along a linear groove 1a of a fixed barrel 1. Thus a macrocontrol is performed to a close-distance subject.
