Patent JP-H0682009-A (JP)
Title: Burner
Inventor: SHIMAZU MASAHIKO
IPC: F23D14/08
Filed: 1992-08-31
Abstract: PURPOSE:To stabilize both ends of flame, eliminate the generation of unburnt gas and prevent the overheat of a burner case 1 in a thick and thin fuel combusting combustion device where a plurality of combustion pipes are juxtapased in the burner case. CONSTITUTION:A plurality of combustion pipes are internally installed to a burner case 11 where a thick fuel gas burner port 6 is formed in the central part of the combustion pipe while a thin fuel gas burner port 9 is formed both ends of the pipe. A block plate 13 is mounted to a secondary air nozzle of the combustion pipe on both ends. This prevents the secondary air from flowing into the secondary air nozzle on both ends so that no thin fuel gas flame may be formed on the side of a burner case. It is, therefore, possible to prevent the generation of lifted flames and hence eliminate unburnt gas. It is also possible to protect the burner case from being overheated by the air flowing along the burner case.

Title: Reproduction unit
Inventor: KUSHIMA TATSUYA
IPC: G11B15/087
Filed: 1995-09-11
Abstract: PROBLEM TO BE SOLVED: To obtain a reproduction unit in which the high speed transfer of.tape can be ended at an appropriate position without requiring any motor brake by turning a reel reversely with respect to the inertial rotational component thereof when a reel motor is stopped during AMS operation. SOLUTION: When a section between musics is detected during AMS operation, drive control of a reel motor 10 is interrupted. The reel motor 10 is driven to turn the reels 22, 23 reversely by an amount corresponding to the rotational amount of reels 22, 23 at the time of interrupting the drive control including the inertial rotational component thereof. More specifically, the reel motor 10 is stopped naturally by simply interrupting the drive control without using any motor brake and the reels 22, 23 are turned reversely for the inertial rotational component thereof thus ending the tape feed operation at an appropriate section between musics.

Filed: 1995-10-04
Abstract: PROBLEM TO BE SOLVED: To improve operability enabling quick speed-change operation by providing a mechanism for giving resistance to the separation movement between a movable sheave and a fixed sheave. SOLUTION: A condition of the lowest speed position is made wherein the movable sheave 27B of a driving spindle 24 is parted to the utmost to the left part of a paper surface from a fixed sheave 27A, and the movable sheave 34 of a driven spindle 32 is neared to the utmost to a fixed sheave 33. From this condition, when a cam body 30 is rotated in a direction orthogonal to the paper surface, a ring member 28 and the sheave 27B of the driving spindle 24 are pushed to near to the fixed sheave 27A side via a tilted cam surface 30a to increase the winding radius of a transmission belt 23 in a drive pulley PK. Following this, the mavable sheave 34 of the driven spindle 32 is parted to the right part of the paper surface from the fixed sheave 33, thereby speed- changeably operating a continuously variable transmission 1 to a high-speed side.  Also, a coil spring 47 is provided between a spring receiver 46 and a bearing 29 for supporting the ring member 28, thereby giving movement resistance when the movable sheave 27B is parted to the fixed sheave 27A.

Abstract: PROBLEM TO BE SOLVED: To enable measurement even if an inhibiting component difficult to separate is present by arranging three-way changeover valves to the outlet of a separation column and the inlet of a detector and making it possible to change over the post- column reaction condition of the moving phase issued from the column on the way of analysis. SOLUTION: A high performance liquid chromatograph analyzer is constituted so that first and second three-way changeover valves 27, 30 are provided in the outlet of a separation column 26 and the inlet of a detector 35 and first and second reaction pipes 28, 29 are arranged so as to be connected across both valves. First and second reaction reagent quantitative pumps 32, 34 sending first and second reaction reagents 31, 33 are connected to the inlets of reaction pipes 28, 29. A sample to be analyzed is separated into respective components by the separation column 26 and these components are guided to the reaction pipes 28, 29 by changing over the three-way changeover valves 27, 30 corresponding to the kinds of the components and reacted with predetermined reaction reagents to be detected by color development.  Since the selection of the reaction reagent reacting with only an objective component becomes possible, this method can also be applied to a component impossible to analyze under the same post-column reaction condition.

Abstract: PROBLEM TO BE SOLVED: To make it possible to extend and retract an output rod at a high speed or a low speed depending on the external force applied to a work in addition to an ordinary power-operated cylinder operation, by inserting an electromagnetic clutch between a ball screw and a conduction member coupled to a motor. SOLUTION: Electromagnetic clutch 7 is inserted between a ball screw 8 and a coupling shaft 9 coupled to a conduction member 10 for transmitting a torque of a motor 3. Here, when using the motor-operated cylinder for an ordinary use, a current is applied to the electromagnetic clutch 7, thereby coupling the ball screw 8 to the coupling shaft 9. The torque of a motor 3 is transmitted to a conduction member 10 and to the ball screw 8 through the coupling shaft 9 and the electromagnetic clutch 7; and a ball nut 6, a piston 5 and a output rod 4 are slid inside the piston 1. On the other hand, if it is required to operate the cylinder depending on the external force applied to a work attached to the tip of an output rod 4, a current to the electromagnetic clutch 7 should be stopped and the ball screw 8 and the coupling shaft 9 should be separated.

IPC: H01L29/78
Filed: 1988-10-14
Abstract: PURPOSE:To make disconnection failure due to the fusion of a resistance part find it difficult to take place and improve electrostatic breakdown strength of a semiconductor integrated circuit device by making up the resistance part of an input protection device in such a manner that a plurality of polycrystalline silicon wiring parts are connected in parallel. CONSTITUTION:The aluminum part 11 of a bonding pad part is located on a bonding pad opening 12 and three pieces of polycrystal silicon parts 13 are connected to an aluminum wiring part 15 as well as the wiring part of the aluminum part 11 through respective pairs of contact parts 14. Once an abnormal high voltage is applied from the outside, a BVDS transistor of a MOS-FET part 16 of an input protection device is in a state of ON. As an electric charge escapses from this breakdown current to VDD or GND wiring parts, no inner circuit stress is applied. The destruction of the polycrystalline silicon wiring 3 caused by abnormal high voltage from the outside does not have an effect on all three pieces of polycrystalline silicon wiring parts 3 very much and then, electrostatic breakdown strength of a semiconductor integrated circuit device is thus exceedingly improved.
