Title: A/d converter
IPC: H03M1/50
Filed: 1992-03-16
Abstract: PURPOSE:To use an A/D converter even at a high temperature without using an analog amplifier circuit by securing such a function of the A/D converter that can turn the minute change of the voltage signal into the numerical value. CONSTITUTION:The pulse signals PA and PB which are outputted from a control circuit 4 at a fixed interval are inputted to a pulse phase difference coding circuit 2 which converts the phase difference of the pulse signal into the digital data DO1. Thus the circuit 2 can code the time difference between both signals PA and PB. Meanwhile the voltage signal Vin to undergo the A/D conversion is inputted as the power voltage of the inverting circuits (NAND and INV) included in pulse rounding circuit 10 forming the circuit 2. As a result, the inverting time of each inverting circuit is changed by the signal Vin and the data DO1 outputted from the circuit 2 has the value corresponding to the signal Vin.

Title: Ribbon bonding device
Inventor: MATSUMOTO KAYO
IPC: B23K26/21
Filed: 1988-03-14
Abstract: PURPOSE:To allow ribbon bonding and ribbon-like thin metal bonding onto fine portions to be performed easily and accurately by irradiating a laser beam onto a portion of ribbon like metal to be bonded through a columnar lens which is brought into contact with the portion of ribbon-like metal to be bonded. CONSTITUTION:A board 1 is fixed on an X-Y table 10 and a bonder head 12 is lowered to a position where a columnar lens 14 is focused on a ribbon-like metal 3 of the board 1. When a laser beam is injected from a laser oscillating unit under this condition, the laser beam is irradiated onto the ribbon-like metal 3 from the columnar lens 14 through a laser optical path within a sleeve 13 by an optical fiber 15. Accordingly, the ribbon-like metal 3 is bonded onto a conductor pattern 2 by heating. At the time of such a bonding by heating, the columnar lens 14 presses the ribbon-like metal 3 by a small force derived from the lowering of the bonder head 12, and this allows the ribbon-like metal 3 to be subjected to thermocompression bonding with respect to the conductor pattern 2, whereby the ribbon-like metal 3 can be bonded accurately.

IPC: C02F1/44
Filed: 1991-02-28
Abstract: PURPOSE:To improve the pressure withstanding strength and passability of an overall filtration-type hollow-fiber membrane module by decreasing the diameter of the micropore on the outer surface of a hydrophobic porous body. CONSTITUTION:A gas such as air staying in the outer cylinder of the hollow- fiber membrane module is passed through the micropore 6 of a hydrophobic porous body 3 and discharged from the outer cylinder. Since the diameter (d) of the micropore 6 opened on the outer surface of the porous body 3 is reduced, the bacteria, etc., are removed by the open part, and the gas is passed through the large-diameter micropore 61 and smoothly discharged. Besides, as the porous body 3 is basically solid, the pressure withstanding strength is kept high. The durability is further improved by using a hydrophilic porous body as the filter medium.

Title: Medical insertion aid
Inventor: MINAMI KYOKO
IPC: A61M25/00
Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To eliminate the possibility of damaging organic tissues without making a patient feel discomfort and aches by bringing the internal wall of the far end of a sheath into close contact with the external wall of a dilator to reduce resistance during the insertion into an organic tissue when the dilator is inserted into a lumen of the sheath and bent. SOLUTION: A dilator hub 14 is fitted into a sheath hub 4 and, when a dilator 12 is inserted into a lumen 1 of a sheath through a dilator insertion port 6 and a hemostatic valve 8, the far end 15 of the dilator 12 sticks out of the far end 5 of the sheath and the internal wall of the far end of the sheath gets tight on the external wall of a reduced diameter part 18 of the dilator 12. In this manner, as internal and external walls get closely together while the diameter of an expanded diameter part of the dilator 12 becomes larger, the far end 15 becomes hard to bend so that the degrees of bending become equal between the dilator and the sheath. Thus, even if the medical insertion aid is inserted being bent, the far end 5 of the sheath will not separate from the dilator thereby reducing the insertion resistance.
