Title: Injector having luer lok part
Inventor: SUDOU MORIHIRO
IPC: A61M5/34
Filed: 1997-10-27
Abstract: PROBLEM TO BE SOLVED: To keep a Luer-Lok part from being broken even when a connection part is excessively screwed in, by forming the lower final end part of at least one of spiral threads of the Luer-Lok part at a position higher than the top surface of a bottom part between both cylinder parts. SOLUTION: Lower final end parts of at least one of at least two, normally two threads (a) and (b) parallel with each other or preferably all the threads formed on the inner circumferential surface 2' of an external cylinder part 2 of a Luer-Lok part are formed at a position higher than the top surface 5 of a bottom part between two cylinder parts. Therefore, even when the lower final end part of the thread a' of the connection part 8 is screwed in beyond the lower final end part of the thread (a) formed on the inner circumferential surface 2' of the external cylinder part 2, since there is not thread (a) at this part, the lower final end part of the thread a' is bent upward to weaken a force pushing the external cylinder part 2 outward. This enables avoiding of the concentration of a stress about the root of the external cylinder part 2, thereby preventing breakage near the root.

Title: Current detector for controlling vehicle traveling motor
Inventor: TSURUMI TAKASHI
IPC: B60K6/26
Filed: 1999-10-29
Abstract: PROBLEM TO BE SOLVED: To provide a current detector for controlling a vehicle running motor capable of dispensing with a high-accuracy power supply circuit, using a comparatively low-accuracy inexpensive power supply circuit and obtaining high- accuracy measurement results. SOLUTION: A power supply circuit 33 converts the input voltage of 12 V to voltage of 5 V and outputs the same to a current detector 125u for controlling a vehicle traveling motor. The voltage of 5 V is input to a current sensor 21. On detecting a current value of a current flowing through a conductor L, the current sensor 21 converts the detected current value to a voltage signal and outputs the same to an A/D converter 23. The A/D converter 23 converts the voltage input from the current sensor 21 to a digital value and output the same. In the thus constructed circuit, voltage is supplied to the current sensor 21 and the A/D converter 23 from the same power supply circuit 33, whereby even if the voltage Vs of the power supply circuit varies, the A/D converted value is not influenced by such variation.

Title: Shape of outer lead of tab
Inventor: ITO TAKASHI
IPC: H01L21/60
Filed: 1990-11-16
Abstract: PURPOSE:To reduce a solder bridge and to enhance the yield of a soldering operation by a method wherein connecting parts of outer leads are formed in a plurality of rows so that the leads can be connected easily even when the pitch between the leads is made fine. CONSTITUTION:Connecting parts of outer leads 1, 2 are arranged in two or more rows. Consequently, the distance between bonding parts can be separated. For example, when they are formed in two rows, the connecting parts of the outer leads are arranged alternately, the pitch of their bonding parts can be made doubly coarse, and the distance between the bonding parts can be made twice or higher. That is to say, when the width of the outer leads is designated as (a) and the interval between the leads is designated as (b), the pitch of the bonding parts is doubled as 2a+2b, and the interval between the leads 1, 2 becomes twice or higher as a+2b. Thereby, even when the pitch between the leads is made fine, the leads can be connected easily to the outside, a solder bridge is reduced and the yield of a soldering operation can be enhanced.

Title: Two-sheet detection device
Inventor: SHINOHARA YASUHIRO
IPC: B23Q7/00
Filed: 1992-10-27
Abstract: PURPOSE:To enable the number of sheets to be accurately checked in a state that each work to be transferred is being loaded by measuring only load applied to a loading mechanism by each work through a load plate, and thereby devising any force reversely exerted in the aforesaid loading direction not to be applied to a pressure detecting section. CONSTITUTION:The base shaft 4b of a loading mechanism 4 is tried to be slid upward by means of pressing force, however since the base shaft is so constituted that its components are slidably and mutually penetrated through, force exerted upward is brought in contact with the lower surface of a rest table 3 so as to be applied to the upper surface of a lower side ring 4e via a coil spring 4f provided around the base shaft 4b, therefore, the influence of pressing force from below is blocked by the rest table 3, a load plate 2 is thereby not affected at all. Next, when the transfer mechanism main body of the equipment is raised up, each work is lifted up, downward load by each work is substantially applied to a fixture 4c fixed onto the base shaft 4b of the loading mechanism 4, however load applied to the fixture 4C is transmitted to the load plate 2 through a load ring 4d, so that load is detected by a pressure detecting section 1.
