Title: Cmos image pickup device provided with a/d converter for every pixel
Inventor: MARTIN DAVID A
IPC: H04N5/378
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To provide an image sensor capable of being manufactured by using a CMOS process. SOLUTION: Lamp signal generators 30 and 32 are provided with a counter 32 and a D/A converting circuit 30 having the analog output of the D/A converter 30 for forming an analog lamp input to a comparator circuit 18. The counter circuit 32 is used for driving the digital side of the D/A converting circuit 30 and constituted so as to perform counting from 2n-1 to 0 and in this case, (n) is the resolution of a photosensor 16. When a lamp signal is equal with the output value of the photosensor 16, the output of the D/A converting circuit 30 flips the comparator circuit 18. When flipping the comparator circuit 18, on the other hand, the comparator circuit 18 drives a load signal to a register 38 for storing a counter value 32 from a pixel 14. Thus, the A/D conversion of image data is performed.

Abstract: PURPOSE:To obtain constant tightened condition at all times by mounting a wall which rises at a position outside of a head section at height where the head section is disengaged with a rotary tool owing to a combination of a screw which has the polygonal head section and a washer provided with a hole through which a shaft section of the screw passes. CONSTITUTION:A rotary tool 21 is engaged with a head section 5 and a shaft section 2 is screwed in toward the fixed object A and mother material B in the condition where a washer is engaged with and inserted in the shaft section 2 of a screw 1. When screwing of the screw 1 advances and the head section 5 approaches a washer 11, the tip of the rotary tool 21 contacts a wall 14 of the washer 11, and the rotary tool 21 cannot advance any more. However, the screw 1 is rotated by the rotary tool 21 and advances further because the head section 5 is engaged with the rotary tool 21. When the bottom face of the head section 5 of the screw 1 contacts a face 15 of the washer 11 and the washer 11 is pressed by the mother material B via the head section 5 and the fixed object A, the head section 5 is housed in the wall 14, the rotary tool 21 is disengaged with the head section 5, and the screw 1 cannot be screwed in any more.

Title: Joint structure of passage tube
Inventor: ITO YASUNOBU
IPC: F25B39/02
Filed: 1989-05-18
Abstract: PURPOSE:To prevent abnormal noises having peculiar frequency from being caused by disposing a protuberant part provided in such a manner that its top end part is expanded outwardly toward its downstream side, and by providing a second passage tube through which a fluid flows into, or out of, a first passage tube. CONSTITUTION:Refrigerant gas that has flowed into an outlet tank part 33 of each of tubes 3 is all allowed to flow into the outlet tank part 33 of the outermost tube 6 being a second passage tube. The refrigerant gas thus flowed thereinto flows into a protuberant part 76 formed on the outermost molded plate and passes a top end part 75 protuberantly provided inside an outlet pipe 5 through a communicating port 51 protuberantly provided inside the outlet pipe 5 being a first passage tube. In this case, the top end part 75 is caulked outwardly toward its downstream side so that its sectional shape has a substantially U-shaped state, and is so formed that its sectional area gradually decreases in the direction in which the refrigerant gas flows. Accordingly, the top end part 75 does not have such a length as to act as a resonance tube. Therefore, when the refrigerant gas passes through the interior of both of a fitting part 74 and the top end part 75, abnormal noises having peculiar frequency can be prevented from being caused.

Abstract: PURPOSE: To enable the discharge to be started easily, and enable the start easily and exactly, by means of connecting a start voltage generating circuit comprising of a resistance heating unit and a thermosensing switch in series with an adjacent conductance.  
     CONSTITUTION: When feed is started, current flows in a resistance heating unit 7 via an adjacent conductance 9. A large electric potential tilting is generated between another electrode 3 by the adjacent conductance 9. A high voltage generates by the inductance etc. at the same time, and is impressed between electrodes 2, 3 of a luminous tube 1 by means of being opened by a thermosensing switch 8 by the heat of the resistance heating unit 7. Because the current which was flowed in the adjacent conductance 9 is broken at the same time, the magnetic field generated in the luminous tube 1, is rushly changed, and enables the start of the discharge in the luminous tube 1, and the starting voltage is lowered. After the luminous tube 1 being started, a bimetal switch 10 is opened, and separates electrically the adjacent conductance 9 from one side electrode 2.
