Title: Nozzle for ink jet recording head and preparation thereof
Inventor: SUGA MICHIHISA
IPC: B41J2/055
Filed: 1982-12-10
Abstract: PURPOSE:To maintain the directional stability of ink jet even in longtime use, by a method wherein the leading end part of a jet orifice is formed in a straight tubular shape and the cross-sectional area with respect to the plane vertical to the ink jet direction of the wall part around the jet orifice does not exceed the area of the jet orifice while the thickness of the wall part around the jet orifice is made thin. CONSTITUTION:A nozzle consists of a conical part 202 of which the outer shape is squeezed toward the leading end 201 of the nozzle and the cylindrical part 203 of the nozzle leading end. The wall thickness of the conical part 202 becomes small toward the nozzle leading end 201 and the wall thickness becomes almost constant in the leading end cylindrical part 203. This nozzle is enabled in ink jet having good directional stability even after allowed to stand in a room for six months or more. If the cross-sectional area due to the plane vertical to the ink jet direction of the wall part around the jet orifice of the nozzle is within a range not exceeding the area of the jet orifice, ink jetting pratically sufficient in directional stability can be realized.

Patent JP-S6275369-A (JP)
Title: Radiation detector
Inventor: KITA YOSHIO
IPC: G01T1/26
Filed: 1985-09-30
Abstract: PURPOSE:To facilitate the derivation of radiation energy, by reducing heat radiating rate in a radiation detector. CONSTITUTION:A radiation energy is absorbed by an energy absorbing body 3 as heat energy. The heat energy is transmitted to a metal pattern resistance 107 through an insulator sheet 105 to change the temperature of the resistance 107 causing a change in the resistance value of the resistance 107. The radiation energy corresponding to the change in the resistance value is computed by a specified formula on the balance of energy. When the size of the absorbing body 3 is reduced to that almost the same as that of the resistance 107, the heat energy leaking to a frame 113decreases. A lead section 5 is made up of a gold wire with the desired thickness and length to reduce the heat energy (thermal conductivity coefficient) which may leak to an external lead 111 of a metal resistance borometer 1 from the lead section 5 to a negligible level. This facilitates the derivation of radiation energy through the neglect of the thermal conductivity coefficient in the specified formula on the energy balance.

Filed: 1999-07-30
Abstract: PROBLEM TO BE SOLVED: To simplify the structure of a cabinet having both the function of preventing drawers from being doubly drawn out and the function of automatically drawing the drawers in. SOLUTION: A guide element 8 is secured to the inner side face of a cabinet body in such a manner as to correspond to each drawer, and an actuation member 9 is attached to the guide element 8 in such a way as to freely move back and forth. The actuation member 9 advances by a certain dimension as the drawer is drawn out, and assumes a forwardly inclined attitude once fully advanced. When the drawer is pushed in, the actuation member 9 is returned to a horizontal attitude by the pressing action of an engaging pin 22 provided on the drawer, and at the same time the engaging pin 22 is engaged into an engaging groove 21. Because the actuation member 9 is moved backward by a spring 25, the drawer is drawn into the body. When the actuation member 9 advances, an interlocking rod 15 for preventing double drawing-out rises.  Then a body side stopper 30 is situated just in front of the drawer-side stopper 31 of another drawer, which cannot then be drawn out.

IPC: G03C3/00
Filed: 1988-08-31
Abstract: PURPOSE:To extend an effective photographing area and to improve picture quality by feeding a film without using a sprocket and perforations for feeding a film. CONSTITUTION:A black box opening on the film contact side is almost 30mm long in the width direction of the film so that an oblong effective photographing area, with almost 30mm long at least in the width direction of the film, is formed on the 30-mm-wide film. That is, the film 1 is 35mm wide, which is equal to the width of the present film, and has no perforations. A frame 3, an effective photographing area, is 30mm long in the width direction of the film. Perforations are eliminated from the 35-mm-wide film, and the frame is extended, in the width direction of the film, to the position where perforations are made. Thus, a practical effective photographing area is extended by about 40 percent, and picture quality is improved.

Title: Method and device for base station multiplexing
Inventor: FUJIMOTO ATSUSHI
IPC: H04W92/20
Filed: 1995-08-03
Abstract: PROBLEM TO BE SOLVED: To enable operation for many base stations with a small number of digital lines even in an area wherein radio zones of low traffic are successively present. SOLUTION: A radio link connects a master base station BM which accommodate digital lines and a plurality slave base stations BS which operate under the control of the master base station BM in a loop by radio lines, and the respective base stations interface with mobile equipments PS in the areas that they are in charge of. When the radio link is in normal operation, transmission and reception are performed through the unidirectional route of an adjacent slave base station BS and if a fault occurs to the link, signals are returned at the fault place and sent and received in a bidirectional route. Consequently, the operation cost is low with a small number of digital lines, and the restrictions of installation places of the base stations are small; and base stations can be increased and decreased in number and speedy measures against fault occurrence can be taken.
