Title: Cassette tape recorder
Inventor: NAKAYAMA YUSUKE
IPC: G11B15/30
Filed: 1985-12-17
Abstract: PURPOSE:To essentially enlarge a space volume in an electronic equipment pack by providing a reel device which can remove essentially the electronic equipment pack when it is put into a tape cassette storing part. CONSTITUTION:When a tuner pack to which the space to store a reel is not hollowed, is mounted into a tape cassette storing part, a reel cap 11 is pushed downward and a reel claw 14, a transferring gear 17 and a reel shaft 18 accompanied to the cap 11 are simultaneously pushed downward by it. Thus, the reel as a whole pushed downward is held by a spring 15, and the cap 11 is descended until a washer 13 is abutted with the upper part of a reel bearing, the gear 17 is abutted with a chassis 20 or the reel shaft 18 is abutted with a cabinet 21. Consequently, by the constitution, the cap 11 can be descended up to the vicinity of a bottom surface position 22 of a tuner pack, and the actually loaded volume of the parts, which can be stored into the tuner pack, can be increased.

Title: Thin film solar cell
Inventor: YOKOYAMA TAKASHI
IPC: C30B29/06
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To eliminate the need of a process for giving a texture structure to a thin film solar cell from the manufacturing process of the cell by forming the thin film of the cell so that the crystal depositing surface of the thin film formed by liquid phase epitaxy can have the texture structure by growing (111)-slopes on the surface by utilizing the crystal orientation of the thin film and the base of each pyramidal projection constituting the structure can have a specific size. SOLUTION: Since a substrate 27 is dipped in a solvent 50 while the solvent 50 is stirred by inversionally moving a holder section 22 after a solute is diffused in the solvent 50, an Si crystal thin film having a uniform thickness can be obtained, because the solute is not biased. The surface of the formed Si crystal thin film constitutes a texture structure as it is, because (111)-slopes preferentially grow and pyramidal projections 51 continuously stand in lines on the surface. When this Si thin film is used as a solar cell, therefore, the process for forming the texture structure by etching becomes unnecessary. The base of each projection 51 has a size of 1-500μm which is effective to reduce the light reflectivity of the surface.

Title: Polarized wave coupler

IPC: G02B27/28
Filed: 1988-11-11
Abstract: PURPOSE:To make loss due to absorption small and to eliminate the dependency of the output level of monitor light, etc., upon the plane of polarization of incident light by arranging a branch prism so that a plane of incident light by arranging a branch prism so that a plane of incidence upon a dielectric multilayered film is at 45 deg. to two planes of polarization of incident light. CONSTITUTION:The branch prism 16 arranged on the optical axis of projection light of a polarized light coupling prism 11 is in the same shape as the shape of the polarized wave coupling prism 11. Then the branch prism 16 is moved in parallel along the optical axis of projection light from the position of the polarized wave coupling prism 11 to have the position relation of 45 deg. rotation around the center of the optical axis, and consequently the incidence surface of the branch prism to the dielectric multilayered film 19 is at 45 deg. to the plane of polarization of light from an input port 2. Consequently, a P-wave component and an S-wave component to the dielectric multilayered film 19 become uniform as to the reflection or transmission of the dielectric multilayered film 19 to eliminate the polarized wave dependency of the branch ratio of the branch prism 16 and also reduce the loss due to absorption.

Filed: 1990-10-22
Abstract: PURPOSE:To reduce the loss due to decrease in Q by forming a 1/4 wavelength resonator with two resonator type lines and a varactor diode connected in series between the resonator type lines and coupling the resonators with n-sets of coupling capacitors. CONSTITUTION:A 1st stage microwave filter is formed with resonator type lines 1,2 and a varactor diode X1 connected between the lines, and a 2nd stage microwave filter is formed with resonator type lines 3,4 and a varactor diode X2 connected between the lines. Moreover, the electric length of the series connection of the lines 1,2 and that of the lines 3,4 almost corresponds respectively to lambda/4. Then the capacitance of the varactor diode is changed by a bias voltage from a control terminal 13 thereby varying a center frequency of each microwave filter minutely. Through the constitution above, the deterioration in the Q of the microwave filter is avoided. Furthermore, a frequency change with respect to the capacitance change is small and fine adjustment is attained.

Title: Compressed voice decoding device
Inventor: HOSODA KENICHIRO
IPC: G10L19/038
Filed: 1992-10-22
Abstract: PURPOSE:To improve the quality of a reproduced voice signal even when a present frame is a bad frame with information omitted. CONSTITUTION:When the present frame is the bad frame and some interpolation processing is not performed, a voice is instantaneously absent and the quality of the reproduced voice signal is degraded. The information of frames in the past can be utilized for the interpolation but even in this case, the interpolation is not satisfactorily performed and the quality of the reproduced voice signal is degraded sometimes. Therefore, when the present frame is the bad frame, an interpolation processing part 23a interpolates the information of the present frame by using the information of frames in the past and future rather than the present frame, and the quality of the reproduced voice signal is improved by performing decoding processing while using the interpolation information.

Abstract: PURPOSE: To enhance safety of traveling of a car, in a paving body laid in a superhighway or an ordinary road, by improving the durability of the paving body to largely reduce the frequency of repair or maintenance work and reducing defects which occurs on the surface of a road. CONSTITUTION: Wear resistant aggregates 7 (7a, 7b) are mixed into a rubber material 6 to mold it into an elastic board 2. The board 2 is laid on a bedrock 3 and fixed by means of a fixing means 20 to form a paving body.

Since the rubber material 6 has a high weather resistance, plastic deformation thereof is small and furrows are not practically produced by wheels of car. Further by providing grooves 26 in the surface of a road in the direction of traveling of cars, wheels can be guided and by applying light reflecting paint into the grooves 26, a traffic lane can be clearly shown to a driver during the night.
