Title: Screen printer
Inventor: ASAI KOUICHI
IPC: B41F15/40
Filed: 1993-12-24
Abstract: PURPOSE:To provide a screen printer capable of adjusting a contact load of a squeegee upon a screen accurately. CONSTITUTION:A squeegee 112 is lowered during screen printing, and if it is further lowered from a state that it is in contact with a screen 80, the contact load of the squeegee upon the screen 80 increases, and at the same time, the squeegee 112 becomes elastically curved to push the detector 178 of a load cell 170. In this case, the contact load is determined based on a detection signal from the load cell 170, and the squeegee 112 is allowed to come into contact with the screen 80 under an appropriate load by adjusting the lift amount of the squeegee 112. A strain gauge can be attached to the squeegee 112 and the contact load can be detected based on the degree of a distortion shown by the squeegee when coming into contact with the screen 80. Alternatively the residual amount of a printing agent in a printing agent storage container can be determined by detecting a load when the squeegee is not in contact with the screen.

Abstract: PROBLEM TO BE SOLVED: To securely prevent the deflection of a pouch when it is opened, by holding the pouch from both sides by suckers and sucking and opening it by the vacuum pressure and then moving a pair of rows of suckers in a fan-shaped movement around a center made on the extended line of the bottom of the pouch to open the pouch from the upper side one by one. SOLUTION: A pouch taken out of a magazine is delivered to a gripper of a filling and packaging machine and fed to a station to open pouches. A pair of right and left sucker holders are actuated toward the pouch and the suckers 14 (14-1 to 14-2) of both right and left sides vertically arranged in rows by respective sucker holders approach each other at an appropriate distance and stop there by the contact of a positioning stopper 17 for the distance provided at both sides. Then, immediately a vacuum system acts and respective suckers 14 suck both sides of the pouch and subsequently, the sucker holders are unfolded to the outside to form a fan-shape as a whole around the basic axial point 23 and the pouch is opened from the upper part in sequence. In this way, the pouch is shaped to a form decided by the rows of suckers 14.

Title: Device for controlling quantity of light of light source for electronic endoscopic apparatus
Inventor: MATSUMOTO SEIJI
IPC: H04N5/238
Filed: 1989-12-21
Abstract: PURPOSE:To accurately control quantity of light even when the title device is inserted in color temp. environment different from that in a white box after a quantity-of-light control reference level is controlled in the white box by setting the synthetic sensitivity ratio of R, G, B including an illumination system and an imaging system to SR:SG:SB and operating and controlling a quantity-of- light iris mechanism in the almost reciprocal ratio of 1/SR:1/SG:1/SB. CONSTITUTION:The synthetic sensitivity ratio SR:SC:SB of R, G, B is calculated and the mixing ratio of P, G, B in the image signal used in the control of quantity of light is set LR:LG:LB sc as to form a formula LR:LG:LB 1/SR:1/ SG:1/SB. As a result, a reference signal level LC for controlling throttling quantity so as to make the level of the image signal constant by inputting a control signal to a throttling drive mechanism 31 becomes LC LR+LG+LB=K(1/SR +1/SG+1/SB). Since 1/SR+1/SG+1/SB is preset, a throttling controller 32 is operated so that an image is displayed on a monitor screen at a proper brightness level to set the mu-factor K of the output image signal of a CCD 1 inputted to an ALC 30. By this method, the reference signal level LC is obtained and the effect of color can be excluded.

Filed: 1998-11-19
Abstract: PROBLEM TO BE SOLVED: To make the driver aware of the running condition of a vehicle even while automatic steering is in effect by implementing automatic steering control when the switch device of an automatic steering device is on. SOLUTION: Based on operation data received from a main switch 21 and respective steering switches 17a, 17b, an electronic control unit 25 switches over to the automatic steering mode or cancels the automatic steering mode.

Title: Portable manufacturing apparatus for active water
Inventor: SAWA HIDETERU
IPC: B01D29/88
Filed: 1997-12-01
Abstract: PROBLEM TO BE SOLVED: To execute activation of water together with removal of hazardous material by a method wherein pressurized water from a pressurized water supply part is supplied to a mixed gas jet current forming part to form a mixed gas jet current, which is sent to a filter medium storing part. SOLUTION: Pressurized water of a water system is supplied to a spraying nozzle 14 via a water feed hose 3. Thereby, the pressurized water is sprayed as a jet current toward an impact surface 16 from the spraying nozzle 14 to generate a negative pressure around that. The air is sucked from an inlet port 15 with the negative pressure, taken into the jet current to form a mixed gas jet current, which is blown against the impact wall surface 16. An air bubble in the mixed gas jet current is finely crushed thereby, and a contact surface of the jet current with the air bubble increases. Therefore, a dissolved oxygen amount increases, and chlorine or the like is discharged from the jet current by the aeration effect. Thereafter, the product is filtered with filter media 6, and discharged from a discharge opening 8. Activation of water is also executed simultaneously thus.
