Title: Transmission
Inventor: TAKAGI KIYOHARU
IPC: F16H3/66
Filed: 1999-07-29
Abstract: PROBLEM TO BE SOLVED: To provide a transmission having gear speeds of proceeding 6 gears capable of providing an adequate gear ratio, by improving a gear ratio of forward to backward gear speeds to the adequate gear ratio by forming a first row of planetary gears as double pinion planetary gears, and adding a single planetary gear of a second row. SOLUTION: This transmission with 6 forward gear speeds and 1 backward gear speed can be constructed by changing five engaging elements (clutch elements C1, C2 and brake elements B1, B2, B3). Because a ratio of the number of ends of a sun gear S1 of planetary gears of a first row to the number of teeth of a ring gear R1 depends on size when planetary gears of the first row are fixed, planetary gears of the first row are formed as double pinion planetary gears G1. Thus, a gear ratio of forward to backward gear speeds is improved to an adequate gear ratio and single planetary gear G2 of a second row is added, and thereby a gear ratio of forward gear speeds that can not improved by of double pinion planetary gears G1 of the first row is set adequately.

IPC: G05F3/30
Filed: 1993-08-31
Abstract: PURPOSE:To surely rise the constant-voltage output of an output transistor by limiting the output current at a prescribed level when an output electrode is not short-circuited and setting the output current at a level less than the prescribed value when the output electrode is short-circuited respectively. CONSTITUTION:This constant-voltage circuit is provided with the serial resistances 27 and 28 which detect the output current state of an output transistor(TR) 26, and a control means 54 which inhibits the short circuit caused between both resistances 27 and 28 when the output electrode of the TR 26 is short-circuited and falls down to a prescribed voltage level. When the output electrode of the TR 26 is not short-circuited, a resistance 53 constructing a serial resistance is short-circuited and the output current of the TR 26 is limited at a 1st current I0. When the output electrode of the TR 26 is short-circuited and falls down to a prescribed voltage level, the short circuit of the resistance 53 is inhibited and the output current of the TR 26 is limited at a level less than the current I0. Therefore the output voltage of the TR 26 can be surely recovered up to a constant-voltage level when the TR 26 is set free from its short circuit state.

Abstract: PURPOSE:To prevent a tape from being run onto a rotary head drum by shutting a gap between a cover body and the circumference surface of the rotary head drum with a tape shutter, which is turned in the vertical direction when the cover body of a tape cassette is opened. CONSTITUTION:The tip of a tape shutter 27 contacts a circumference surface 4a of a rotary head drum 4 and completely shuts a gap A between a cover body 8 and the circumference surface 4a of the rotary head drum 4 when the cover body 8 is opened. Accordingly, for example, even when looseness is generated in a tape 9 between front opening parts 7a and 7b of a tape cassette 7 to be opened by the opening of the cover body 8 and this tape 9 tends to jump out on the rotary head drum 4 simultaneously with the slight opening of the cover body 8, the tape shutter 27 goes to be a wall and the tape 9 is not run onto the rotary head drum 4. Then, the tape 9 is securely guided between the circumference surface 4a of the rotary head drum 4 and the cassette 7 by the tape shutter 27. Thus, the tape 9 can be prevented from being loaded on the rotary head drum 4.

Title: Solar energy collector
Inventor: AKIYAMA SHIGERU
IPC: F24S10/95
Filed: 1982-12-10
Abstract: PURPOSE:To enlarge a working temperature range of the titled device, by using an alcoholic aqueous solution as the working medium of heat pipe, in a heat pipe type vacuum glass tube-shaped solar energy collector. CONSTITUTION:An aqueous solution B of 85wt% of propylene glycol or an aqueous solution C of 70wt% of ethanol is used as a working medium to be filled into a heat pipe. Because the aqueous solution B has a high boiling point, i.e., about 150 deg.C under an atmospheric pressure, the solution B is filled into the heat pipe after the reduction of its pressure to lower than 0.1kg/cm<2>. The aqueous solution C of ethanol is used only after the reduction of its pressure to lower than 0.1kg/cm<2>. The freezing point of propylene glycol aqueous solution B is about -40 deg.C at the concentration of 85wt%. Similary, the ethanol aqueous solution has the freezing point of about -50 deg.C at a 70wt% concentration. In this manner, the alcoholic aqueous solution can lower a freezing temperature range, prevent the decomposition and metamorphosis at elevated temperature, and thereby allowing an application in an extended temperature range from -40 deg.C to 200 deg.C.

Filed: 1990-08-17
Abstract: PURPOSE:To obtain a liquid crystal(LC) element having no visual angle dependency by constituting the LC element of an LC layer obtained by orienting LC molecules in parallel between substrates and an optical compensating means having an optical axis vertical to the substrate faces. CONSTITUTION:The LC element is constituted of a homogeneous oriented LC cell 101 obtained by orienting LC molecules in parallel with the substrate to execute display operation, and the optical compensating layer 102 not executing display operation. In order to execute display operation, the cell 101 has an electrode structure 103. The layer 102 has its optical axis in the surface normal direction. The double refraction angle of the cell 101 is reduced in accordance with the inclination of incident light from the substrate normal direction. On the other hand, the double refraction angle of the cell 102 is increased. Thereby, the sum of the double refraction angle of both the cells 101, 102 does not sharply depend upon the incident direction of light. In another method, the LC element is constituted of a homeotropic oriented LC cell 401 to be used for display and an optical compensating layer 402. In this case, the optical axis of the layer 402 should be set up to a direction rectangular to an LC molecule orientation direction in the cell 401. Thus, visual angle characteristics can be improved.
