Title: Spray type combustion device
Inventor: OKUBO YOICHIRO
IPC: F23D11/38
Filed: 1986-04-17
Abstract: PURPOSE:To eliminate the blowing-off of flame even in case of the change of swirl air flow and at the same time prevent fuel from passing unburnt through a combustion chamber even when the flow rate of the fuel is large by a structure wherein a twin fluid injection device is provided at one end side of an atomizing chamber, which connects to a swirl chamber and to the other end of which a combustion chamber providing with a throttle is connected. CONSTITUTION:An air inlet pipe 4 is connected tangentially to an annular air swirl passage 3 concentrically formed onto a swirl chamber 2 and, in addition, air inlet holes 6 are penetratingly provided tangentially to the inner peripheral surface of a peripheral wall made between the air swirl passage 3 and the swirl chamber 2. The injection end of a twin fluid injection device is penetratingly attached concentrically to one end of an atomizing chamber 7 on order to form an air supply passage 10 at the peripheral position of a fuel supply passage 9, at the tip of which a fuel jetting needle 12 and a cylindrical swirl chamber 13 are formed concentrically to each other in order to introduce atomizing air flow, which flows in the fuel jetting direction of the fuel jetting needle 12, into the chamber. At the tip of the swirl chamber 13, an orifice 15 is provided concentrically in order to atomize the liquid fuel jetted from the fuel jetting needle 12 by means of the atomizing air flow.

Title: Electrophotographic copying device
Inventor: FUJII YASUO
IPC: G03G21/00
Filed: 1990-04-05
Abstract: PURPOSE:To prevent the deterioration of the quality of a recorded image in the case of recording the image by always setting the photosensitive drum of a photosensitive unit at a specified position to a device main body by an energizing means provided in the device main body. CONSTITUTION:The energizing means 34 for giving force along the direction of the shaft 7 of the photosensitive body 6 to the photosensitive body 6 being a photosensitive cartridge loaded in the device main body 1 is provided in the device main body 1. Since the photosensitive body 6 of the photosensitive unit 5 to which the force in the direction of the shaft 7 is exerted by the means 34 is previously set at the specified position, it is prevented from moving in the direction of the shaft 7 at the time of rotating. Thus, the quality of the recorded image is prevented from being deteriorated by the variation of the position of the photosensitive body 6 in the direction of the shaft 7.

Title: Arc welding method
Inventor: TAKENOUCHI MASARU
IPC: B23K9/00
Filed: 1980-07-02
Abstract: PURPOSE: To eliminate the melt sticking of base metals and a wire electrode and improve welding performance by stopping the feeding of the wire, thence breaking welding voltage and again applying the same and breaking it after a prescribed  time, in stopping welding.  
     CONSTITUTION: The output signal (a) of a main control device 1 is an L level while no welding is accomplished, and when it goes to an H level at the start of welding, a wire feed control device 2 is started; at the same time, a welding power source 10 is started by way of a welding voltage control circuit 7. Hence, a motor 3 is started, by which wire feed rollers 4 are revolved, and a wire 5 is fed to base metals 6; at the same time, welding voltage is applied to generate the arc 16, whereby welding is started. When the signal (a) goes to the L level, the device 2 is stopped immediately, and despite excessive projection of the wire 5 owing to the inertia of the feed mechanism including the motor 3, the electric source 10 is reapplied for a prescribed time after the prescribed time of the breaking of the power source 10 by the circuit 7, and therefore the arc 16 is refired to melt the excessively projecting wire 5, thereby eliminating the melt sticking thereof to the base metals 6.

Abstract: PROBLEM TO BE SOLVED: To obtain a radio base station interface system where high-speed data communication is maintained. SOLUTION: When a mobile station 11 makes a calling operation for high- speed data communication but cannot occupy consecutive time slots, the mobile station 11 transmits an instruction of switching a time slot B4' from a synchronization channel to a speech channel in the case that the time slot B4' is idle. When a synchronizing signal having so far been sent by using the time slot B4' is stopped, a radio base station 2 applies self-running to a counter circuit holding a synchronization timing in the inside of the radio base station 2 so as to maintain a synchronization phase having so far maintained. The radio base station 2 establishes the call by assigning 64 kbps data from the mobile station 11 to consecutive time slots B3', B4' on the basis of an instruction from an interface circuit of the radio base station.  A selector can directly connect the 64 kbps data to a time slot B3 having a transmission rate of 64 kbps on a time division switch.
