Title: Method and apparatus for inputting white balance calibration light
Inventor: TAKANO MASAYO
IPC: H04N9/04
Filed: 1998-06-16
Abstract: PROBLEM TO BE SOLVED: To input a white balance calibration light uniformly to a photodetector at an image formation face by arranging a spider of an optical fiber in front of an optical system, inputting the white balance calibration light from an end face of the optical fiber and projecting the light from a side face. SOLUTION: In order to input a white balance calibration light to detect a detection sensitivity variation at a light detection face of a photosensor or the like, a spider 1 of a crossed optical fiber is used which is arranged in front of an optical system 2 of the photosensor. The optical fiber is shaped like a circular rod having an input and an opposite end for the white balance calibration light. A reflecting agent is applied to the opposite end to make the opposite end a reflecting face. A part of a half circumference of a side face of the optical fiber is polished and flawed minutely to leak the light. A predetermined calibration light 4 input from the input end of the spider 1 advances repeating reflections, is reflected at the opposite end and returns.  In this process, the calibration light is radiated to a photodetector 3 through the flaws at the half circumference part of the side face and enters as a uniform light to an image formation face of the photodetector 3 via the optical face 2.

Title: Improvement in fire resistance performance of hardened material of hydraulic binder
Inventor: MARUSHIMA NORIO
IPC: C04B11/30
Filed: 1995-07-04
Abstract: PROBLEM TO BE SOLVED: To remarkably improve the hardening performances of a hydraulic binder by kneading and hydrating a hardened material of a cement-based hydraulic binder so as to provide the composition of the hardened material of the cement-based hydraulic binder and the ratio of the water to the binder within specific ranges. SOLUTION: A hardened material of a cement-based hydraulic binder is kneaded and hydrated and the ratio of water to the binder thereof is 15-40wt.% to produce ettringite (3CaO.A12 O3 .2CaOSO4 .32H20) and/or an iron type ettringite (3CaO.Fe2 O3 .3CaSO4 .32H2 O). Thereby, fire resistance performances of the hardened material of the hydraulic binder are improved. Preventing effects on explosion possessed by the ettringite are manifested according to this method and the explosion can completely be prevented while maintaining the strength as a high-strength concrete. Since sharp-cornered grains possessed by a slag or gypsum especially form fine voids in the hardened material, a rise in pressure is suppressed in dehydration to prevent the explosion.

Abstract: PROBLEM TO BE SOLVED: To provide the communication equipment of channel data automatic setting type where the operability is enhanced, the operation is facilitated and revision of channel data having been generated and revised by a channel data input device by automatic data setting is prevented. SOLUTION: A channel data input device 1 receives input of channel data and stores them to a channel data storage section 33 of a storage device 3 that stores the channel data through a channel data control section 4 and sets an input state of the channel data of a channel data input state storage section 31 to be an input finished state. When a channel containing card mount detection section 2 detects mount of a channel container card 5, the detection section 2 informs the channel data control section 4 of it, generates channel data by using standard channel data stored in a standard channel data storage section 32 when the channel data input state indicates a no-input state and stores the data to the channel data storage section 33. When channel data are already received, the channel data are no longer generated.

Title: Switching device depending upon temperature and/or current
Inventor: PEETAA HOOFUZEESU
IPC: H01H81/02
Filed: 1983-09-16
Abstract: For stopping drift or other undesired changes in the response temperatures of a thermal switch using a bimetallic element for driving a moving contact, the design is such that the moving contact and a counter-contact are supported on a common insulating supporting part and the counter-contact is elastically and yieldingly fixed on the supporting part. The lengths of the bimetallic element and of the a strip supporting the counter-contact that may be moved are different to each other so that the two contacts will make contact at different points thereon and with a rubbing effect for clearing oxide and other undesired coatings forming on the said contacts. For producing such a thermal switch with multiple functions, for example the functions of a temperature automatic controller and a thermal protective device, the counter-contact, that is placed so that it may give way elastically, is acted upon by a further bimetallic element.

Title: Ink jet printer head and its manufacturing method
Inventor: FURUICHI MIKI
IPC: B41J2/135
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To ensure fine fabrication more positively and enable cost reduction by performing a plating process to realize the growth of a plated layer by the same length as a parallel part from an insulating base side to the top part of a resist for molding a nozzle hole along the surface of the resist. SOLUTION: A mold 30 is immersed in a nickel electrodeposition liquid and a plated layer 26 is electrochemically deposited by applying electric current to the electrodeposition liquid at 5-20A per 10×10cm for about one hour, and the current application is suspended when the estimated thickness A (about 100μm) of a head base 11 is reached. Thus the growth of the plated layer 26 is inhibited by forming a resist base 22b on a nickel film 21, and a nozzle hole of the estimated diameter 12 is prevented from being blocked, so that the nozzle hole 12 is formed to the accurate diameter. After that, the mold 30 is separated from the plated layer 26 to obtain an ink jet printer head with a plural number of nozzle holes 12 of specified shape formed on the head base 11. Further, the printer head is treated for water repellency as a finished product.

Filed: 1983-09-14
Abstract: PURPOSE:To realize a linearization of a high level by setting an incident angle to a hologram disk, to an optimum incident angle, setting a lattice surface of a hologram lattice and a scanning surface to a conjugate relation with regard to a specified direction, and forming an image on the scanning surface by a scanning beam. CONSTITUTION:A diffracted light LB10 which has been made incident on a hologram disk 1 at an optimum incident angle and generated is made incident on a spherical lens 40 through a plane mirror 3, passes through a cylindrical lens 8 and reaches a scanning surface 5. The spherical lens 40 and the lens 8 link a lattice surface of a hologram lattice 10-i and a scanning surface to a conjugate relation in the direction orthogonal to the scanning direction. According to such a constitution, a position of an image on the scanning surface of an optical beam is determined clearly with respect to a position of the optical beam on the lattice suface, and since an incident position of the optical beam to the lattice surface is constant and invariable, a position of an image on the scanning surface is also constant and invariable with regard to the direction orthogonal to the scanning direction, the scanning line becomes a straight line theoretically, and a shift from the straight line can be reduced to the extent that it is scarcely measured.

Abstract: PURPOSE:To eliminate load on bonding sections of a panel driving IC, by pressing the surface of a film carrier by means of a film carrier pressing plate while elevating a pin further, for positioning the film carrier. CONSTITUTION:A film carrier 3 is inserted in a pin 11 serving as a reference such that only the tapered portion of the pin 11 projects from the surface of a slide base 8. A film carrier pressing plate 22 is automatically lowered to press the surface of the carrier 3 while, simultaneously, the pin 11 is elevated. Thus, the film carrier 3 can be positioned smoothly. In order to withdraw the pin 11 from the carrier 3, the pin 11 is automatically lowered with the plate 22 in the lowered position and the plate 22 is elevated when the pin 11 has been lowered completely. One cycle is completed in this manner. It is thereby possible to eliminate load on bonding sections of a panel driving IC.
