Abstract: PURPOSE:To make the connection of a lead wire and a socket secure and easy by pressure-welding a core wire to a connecting terminal with a pressing piece after confirming visually that the lead wire and the core wire are loaded at a specific position in a connector. CONSTITUTION:A lead wire 40 is loaded in the housing groove 57 of a lower lid 51 under the condition that an upper lid 53 of a housing 50 at the wire connecting part side is opened, and, a core wire 41 is geared to the notch 63a of a standing piece 63 and the tip of the core wire is extended to a pin connection 61. Then by closing the upper lid 53, a pressing projection 59 presses the core wire 41 to bend in L-shape to pressure-weld the core wire 41 to a connecting terminal 60, and at the same time, the upper lid 53 and the lower lid 51 are geared each other. Then, by inserting the base of a fluorescent lamp in a housing 30, the fluorescent lamp pin is geared to the terminal 60 and the electric connection is made. As a result, the lead wire and the core wire can be confirmed visually to be housed at a specific position in a connector, and the lead wire and a socket can be connected securely and rigidly, electrically and mechanically.

Title: Controlling method of film thickness of resin-covered steel pipe
Inventor: INOUE YOSHIHIKO
IPC: B29C63/04
Filed: 1982-07-22
Abstract: PURPOSE:To save the amount of a resin used, by suitably controlling the operation of a guide roll that gives tension to a sheet between a resin delivering port and a steel pipe so that the thickness of the sheet is efficiently increased only around the part of the steel pipe where it is welded. CONSTITUTION:The guide roll 11 is positioned at its pushing position A to give the sheet 5 a prescribed tension while the sheet 5 is wound around the steel pipe 7, and when the sheet is wound around the welded section of the steel pipe 7, the tension is relieved so that the sheet thickness is locally increased at that section. When the tension is relieved, the guide roll 10 is queickly moved to thicken quickly the sheet 5 as indicated at X, and at the moment when the guide roll 10 reaches its retracted positions B where the tension of the sheet is relieved to the utmost, the guide roll 10 is moved reversely, that is in its pushing direction Y, quickly to a halfway position P. Before the steel pipe is rotated until the welded section appears again, the guide roll is gradually brought from the halfway P to the pressing position as indicated at Z.

Title: Method of carrying component
Inventor: SHIMANUKI YOSHIHIKO
IPC: H05K13/02
Filed: 1988-05-27
Abstract: PURPOSE:To carry an electronic component with the leads less deformed, by covering the leads of the electronic component with a solder material so that the thickness may be larger than that of a package and the height may be larger than that of the principal surface, solidifying them, containing an electronic part into a container, and carrying it. CONSTITUTION:Each packed semiconductor device 1 having leads 4 covered by solder 5 is contained in a pocket 7 in a tray 6 and carried in one tray 6 or a plurality of the trays 6. Any shock given during carrying is absorbed by the solder 5 covering the leads 4 and a group of leads 4 in said solder 5 because each packed semiconductor device 1 moves within the pocket 7 in the tray 6 to contact the solder 5 with the sides or the bottom of the pocket 7. This decreases a shock given to the specific lead in comparison with that given to a lead 4 not covered to carry the semiconductor device with the leads less bent. Packaging can be performed by heating the packed semiconductor device and melting the solder 5.

Title: Key input processing device
Inventor: HIGASHIDA TAKASHI
IPC: H03M11/08
Filed: 1987-05-26
Abstract: PURPOSE:To facilitate correction of input by transferring a code determined with operated key switches to a higher-order device and settling the code transferred to the higher-order device just before at the time of simultaneously releasing all operated key switches. CONSTITUTION:If another key is operated when at least one or more keys are operated and a higher-order device 6 displays a character string corresponding to combination of these keys on a display device 7, the code corresponding to combination of keys including another key is transferred, and the code transferred to the device 6 just before is invalidated to erase the display on the display device 7, and a new character string is displayed on the display device 7. If input keys are correct, the settling code is transferred to the device 6 by simultaneously releasing all keys to settle the code transferred to the device 6 just before, and the character string is prevented from being erased by the next key input. Thus, input is momently corrected without inputting a cancel key even if combination of simultaneous input keys is erroneous.

Title: Continuously variable transmission working as clutch
Inventor: ISHIKAWA GOJI
IPC: F16H3/72
Filed: 1990-05-19
Abstract: PURPOSE:To shift rotation of an input shaft into stepless in keeping it connected intact, without separating or replacing some parts, thereby transmitting the rotation to an output shaft by varying the flow or pressure of a hydraulic compressor with a flow controller. CONSTITUTION:In order to transmit rotation transmitted to an input shaft 6 to an output shaft after being shifted, it is necessary to increase or decrease the rotation of one part 2, for example, if the rotation of one part 2 is stopped, the rotation is transmitted to the input shaft 6 and the output shaft 7 at equi- velocity, but if the rotation is done without any restriction, rotation of the output shaft 7 canes to a stop if there is same load in it. Accordingly, when rotation of a hydraulic compressor 3 is shifted by increasing or decreasing the flow or pressure of the hydraulic compressor 3 connected to the part 2, the rotation of the input shaft 6 can be transmitted to the output shaft 7 after being variably shifted (even if the output shaft 7 and the input shaft 6 are in reverse, there is no change in the effect).
