Title: Loading device for information recording disk reproducing device
Inventor: WAKAMIYA KIYOMI
IPC: G11B17/04
Filed: 1985-12-30
Abstract: PURPOSE:To insert a disk case smoothly even when it is inserted in an oblique direction to an insertion opening by constituting a spread mechanism with a spread plate, an oblique shaft, a wedge lever, and a spring. CONSTITUTION:Since an oblique shaft 8b is inclined to an outside (an insertion opening 3 side) having a prescribed angle for the plane of a spread plate 20, a wedge lever is also inclined in the same direction, and as a result, an upper and a lower claw parts 9b are separated from each other according to the turning of the claw part 9b in a counter-clockwise direction, and by that motion, the opening part 41 of a case 2 is spread. by the clash of the end plane of a notch 29b formed at the wedge lever 9b with the other end of a torsion spring 30b, the wedge lever 9b is prevented from turning moreover, and at this time, the spread plate (therefore, the spread mechanism) is pushed and advances to the inner part of a reproducing device.

Title: Ship propulsive device
Inventor: OYAMA KAZUO
IPC: B63H3/04
Filed: 1988-11-28
Abstract: PURPOSE:To prevent an engine or the like from its bad influence due to an overload by providing a torque limiting means between a propeller shaft and a transmission shaft, in case of the captioned propeller pitch variable device. CONSTITUTION:A transmission shaft 2 secures to its rear end side by a nut an inner collar 9 mounting to its periphery a friction member 10 of rubber or the like. The friction member 10 arranges in its periphery an outer collar 11 secured to an intermediate shaft 22 by a nut. And a torque limiter 8 is constituted of the inner collar 9, friction member 10 and the outer collar 11. This torque limiter 8 generates predetermined pressing force limiting transmission torque by elastically deforming the friction member 10. By this constitution, an overload, even when it is generated, can be prevented from giving a bad influence to an engine or the like.

Title: Automatic water squeezing device for hydrous film
Inventor: TOMITA MASAO
IPC: B05D1/28
Filed: 1985-12-29
Abstract: PURPOSE:To obtain a device which can make continuous and smooth squeezing by disposing a differential-diameter press roll which has a large diameter on both end sides to press a feed side belt downward and a small diameter on the central side. CONSTITUTION:Hydrous film pieces F sides on guide roll 9 and are carried underneath the central part of the differential-diameter press roll 10 to the top end of the feed side belt 3a. The film pieces are strongly pressed and dehydrated during the passage between a squeezing roll 4 and a front end side roll 1. The squeezed film pieces are dropped and housed into a container 12 for waste filters. The roll 10 presses both end sides of the belt 3a and deforms the belt 3a to an upward projecting shape. The deformed state is held by the guide roll 9. The water squeezed from the film pieces, therefore, flows smoothly downward and laterally by gravity from the belt 3 face without flowing down by gravity toward rear end side roll 2 along the belt 3a face.

Filed: 1990-11-02
Abstract: PURPOSE:To execute automatically the disposition of peripheral cells similar to that of the peripheral cells in a logic diagram by reading in the disposition of logical symbols of the peripheral cells in the diagram. CONSTITUTION:Simultaneously when information on connections is extracted from a logic diagram, the disposition positions of peripheral cells are determined based on presence or absence of connections of logical symbols of the cells to input-output pins 7, and then it is decided whether the cells are to be disposed on the right or left side, or the upper or lower sides, by determining the direction of rotation of the logical symbols. The disposition is to be made in such a manner that the peripheral cells are disposed as shown by (5a) when the angle of rotation of the logical symbols thereof is 0 deg. or 180 deg. and X<0, as shown by (5b) when the angle of rotation thereof is 0 deg. or 180 deg. from below to above the left side in the sequence of the Y coordinates, beginning with the smallest ones, and X>0, as shown by (5c) when the angle is 90 deg. or 270 deg. from below to above the right side in the sequence of the Y coordinates, beginning with the smallest ones, and Y<0, and as shown by (5d) when the angle is 90 deg. or 270 deg. from the left to the right of the lower side in the sequence of the X coordinates, beginning with the smallest ones, and Y>0. The information on the disposition from the left to the right of the upper side in the sequence of the X coordinates, beginning with the smallest ones, being obtained in this way, automatic disposition is executed based on the above information on connections and the determination of the disposition positions of the peripheral cells, and thereby a desired disposition is attained. By this method, labor for determination of the disposition positions is saved and the time for design of LSI can be shortened.

Title: Optical fiber temperature sensor
Inventor: KUDO AKIRA
IPC: G01K1/02
Filed: 1991-11-15
Abstract: PURPOSE:To obtain an optical fiber temperature sensor as a linear temperature sensor which is suited for measuring a temperature distribution in depth direction of sea-water temperature efficiently. CONSTITUTION:A covering 2 is provided around a tension member 1. The covering 2 separates an optical fiber 3 and a spot sensor 4 from the tension member 1 for ease of sliding, thus preventing expansion of the tension member from propagation to the optical fiber directly. One of two cores of an optical fiber lead wire 3 is connected so that it forms an outward trip with the spot sensor 4. One core is not connected to the spot sensor 4. The two cores are interwound in longer direction and absorption of the tension member 1 can be absorbed by this interwinding effect. Finally, by forming a section shape of the linear body in wedge shape, a directivity of a cable becomes stable owing to a wind effect according to a water flow when being suspended under sea, thus preventing an excessive amount of interwiding from being applied to an optical fiber temperature sensor.

Title: Opening/closing push button device
Inventor: OGURA MICHINORI
IPC: G11B17/056
Filed: 1989-11-17
Abstract: PURPOSE:To obtain an opening/closing push button device whose cost is considerably reduced and operability is improved by arranging the operation parts of an opening/ closing push button at the front surface part and the upper surface part of a cover body to operate a common switch. CONSTITUTION:For the opening operation of the cover body 22, an opening/closing switch 24 is turned on when the front operation surface 23a of the opening/closing push button 23 is depressed, but a disk tray 28 does not advance. When a finger is removed, the push button 23 and the switch 24 are restored and are turned off, the tray 28 starts advancing by electric power. Then, the tray 28 push-opens the cover body 22 against the energizing force of a twisting spring 26 while the tray 28 sticks out and a system comes to a state where the detachment of a disk is attained. For a closing operation, the upper operation surface 22b of the push button 23 faces the front direction of a unit. When it is depressed, the switch 24 is turned on. When the switch 24 is similraly turned off, the tray 28 starts receding, and the cover body 22 closes by the force of the spring 26. Thus, the opening/closing operation of the cover body and the forward/backward operation of the tray can be operated by one push button and one switch, and the cover body is prevented from being abutted on the finger.
