Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To improve the product value and convenience by installing a scale having graduation to be pulled out and pushed in at a proper position. SOLUTION: A scale housing/drawing out mechanism is installed inside of a battery pack main body 12 to be attached to an electronic appliance such as a cellular phone. Receiving members 17, 18 are arranged right and left on the opposite to each other at a proper gap inside of the mechanism and a communicating rod 19 in which the inside end of a spiral spring 20 is fixed is journalled with both members. The outer end of the spiral spring 20 is fixed in an under cover 15. A scale 21 such as a thread is wound on the communicating rod 19 and a window 22 to lead out the scale 21 to the outside is formed in the under cover 15. Since a stopping ball 23 larger than the open part of the window 22 is installed at the tip of the scale 21, the scale is kept in the window 22 part and prevented from being pulled into the battery pack 12.

Title: Standard mechanism in watch
Inventor: TERAMOTO KAZUO
IPC: G04B23/02
Filed: 1980-04-21
Abstract: PURPOSE:To enable the knob to be returned without catching even though hands, standard displays, and the like are turned in either direction, by constituting the standard mechanism by adding a sensing piece to a sensing wheel and a setting wheel. CONSTITUTION:In the case the sensing knob 14 of the sensing wheel 4 is dropped in a hole 10 of the setting wheel 5 and the setting wheel 5 is rotated in the direction of an arrow, the wall of the hole 10 pushes a vertical surface 14'' of the sensing knob 14. However, since the sensing piece having the knob 14 is provided so that it can be rotated by a specified amount with respect to the sensing wheel, the sensing piece is pushed and rotated by the setting wheel 5. A bevel surface 12' of a returning knob 12 of the sensing wheel 4 rises up along the edge of the hole 10 of the setting wheel 5, and the sensing wheel 4 is separated from the setting wheel 5. Therefore, even though the sensing wheel 4 or setting wheel 5 is rotated in either direction, the knob which has dropped in the hole 10 is returned along the bevel surface and is not caught.

Title: Semiconductor storage device
Inventor: WATABE HIROSHI
IPC: G06F12/06
Filed: 1986-03-10
Abstract: PURPOSE:To quickly read back a device from an optional address to address '0' by reset, by constituting a storage plane with static storage cells of a partial area including address '0' and 3-transistor (TR) dynamic storage cells. CONSTITUTION:A data write plane 100 consists of a storage plane 10 of a static storage cell array for a partial area from address '0' to an address (a) and storage planes 20 and 30, where dynamic storage cells each of which consists of three TRs and has a small occupied area are arranged with addresses (a+1)-(b) and addresses (b+1)-(c) as first rows respectively. If the device is reset at an address (i) of the plane 20, the address is returned to address '0' to read data. In this case, data is read out up to the address (a) immediately because the plane 10 consists of static storage cells, and write to planes 20 and 30 having the address (a+1) and following addresses is completed during this read period. Thus, reset from an optional address to address '0' is performed quickly.

Title: Control system for binarization of picture signal
Inventor: YAMAMOTO YUKIHIRO
IPC: G06T1/00
Filed: 1986-03-11
Abstract: PURPOSE:To economize a device by the reduction, etc., of a threshold value register, by fixing a selection means when a dither method and a single threshold value method are used switching them, and outputting a specific threshold value. CONSTITUTION:In a dither mode, different threshold values are outputted sequentially in a prescribed order from a threshold register 20 by controlling counters 12 and 13 by a control part 14. In a single threshold value mode, the output signal of a counter fixing part 21 is set always at '0' during the mode because a mode signal line 8 is set at '0', and the counter 12 and 13 continue states where they are reset in initial states. Therefore, by storing the threshold value set as appropriate in the single threshold value method on the threshold value of the register 20 selected by an address in the state, the threshold value of the single threshold value mode can be supplied to a binarization comparator 6. In this way, only one threshold value register is enough, and also, a selector is made unnecessary, thereby the device can be economized.

Title: Connecting device for reactor control rod driving device
Inventor: KATOU JIYUNGO
IPC: G21C9/02
Filed: 1996-03-11
Abstract: PROBLEM TO BE SOLVED: To provide, a highly reliable connecting device by providing the device with a push-up pin formed of a material having specified dimension and thermal expansion coefficient, and a thermosensitive member formed of a magnetic material having a specified curie temperature. SOLUTION: When the operation of a reactor is normal, and the temperature of liquid sodium is within a normal range less than 640 deg.C, a sufficient electromagnetic attractive force is generated on the attractive surface 23a of an electromagnet 11 to surely hold a control rod 5 through a control rod connecting shaft 41. When the temperature becomes 640 deg.C or more, the upper end of a thermal expanding pin 47 is flush with attractive surfaces 27a, 29a, and when the temperature is 680 deg.C, the pin 47 is further expanded to protrude its upper end from the upper surface of a self-fusion preventing hardware 45, pushing up the magnet 11 to extend the clearance between the surface 23a and the surfaces 27a, 29a, whereby magnetic flux leakage is increased to significantly reduce the holding force.  Thus, the holding force cannot be supported by the dead weight of the control rod 5 and the connecting shaft 41, and is separated and naturally fallen into the reactor core, whereby the control rod 5 is fully inserted into the core to suppress the nuclear reaction.

Filed: 1985-03-18
Abstract: PURPOSE:To enlarge and reduce an image of a body by emitting at least either of two pumping light beams as nonparallel luminous flux and making a composite vector substantially different at each point on a nonlinear medium. CONSTITUTION:A mask 2 is lighted by luminous flux 9 from a laser light source and light transmitted through the mask 2 is object light 10, which is transmitted through a half-mirror 3 and incident on the top surface of the nonlinear medium 1. Laser light 5 having the same wavelength with luminous flux 9 is converged temporarily through the lens 7 of a pumping light generator and then diverged to obtain divergent light 11,which is incident on the top surface of the medium 1. Laser light 6 having the same wavelength of the luminous flux 9, on the other hand, is passed through lenses 8a and 8b constituting a beam expander to become parallel luminous flux, which is incident on the reverse surface of the medium 1. In this case, the main light beam l1 of the divergent light 11 and the main light beam l2 of the parallel luminous flux 12 are aligned to each other. Then, generated light 13 projected from the medium 1 slants slightly to the object light 10 and forms an enlarged image of the mask 2. Further, the image is reduced similarly.
