Title: Method for detecting positional shift in electronic part mounting process
Inventor: MITANI SUKEYUKI
IPC: G01R31/02
Filed: 1989-11-27
Abstract: PURPOSE:To enhance inspection efficiency by bringing a screen mask having electronic part fitting holes prepared by mounting a telescopable member to a frame body into contact with the surface of a printed circuit board after the mounting of electronic parts. CONSTITUTION:A screen mask 1 is arranged on the mounted part inspection table 6 in an electronic part mounting process in a vertically movable manner and constituted so that the mask main body 4 corresponds to the printed circuit board 7 carried onto the table 6 and positioned in place. When the board 7 having electronic parts 9 mounted thereon is fed to the table 6 to be positioned thereon, the mask 1 falls to be placed on the table 6. At this time, the main body 4 comes into contact with the surface of the board 7 as shown by a dot and dash line 14 and the respective parts 9 coincide with electronic part fitting holes 3 to be fitted therein. When the mask 1 is applied on the board 7 in such a case that the position of one of the parts 9 is shifted, a telescopable member 5 extends or contracts to incline the main body 4 and the height H of the mask 1 increases. Then, a position detector 8 is operated and a reflected light is not incident to the light detection part of the detector 8 and a positional shift signal is emitted.

Abstract: PURPOSE:To enable both upper curl and lower curl on a transfer material to be corrected well by providing an upper curl providing roller pair and a lower curl providing roller pair on the downstream side of a fixing device, and distinguishing between the use of these curl providing roller pairs according the image ratio of a document. CONSTITUTION:A lower curl providing roller pair 55 and an upper curl providing roller pair 56 are arranged downstream from a fixing roller 49 and a pressurizing roller 50 of a fixing device 47. These roller pairs 55, 56 can be individually pressurized and released in pressure by solenoids 59, 60. In image forming, since curl is generated on a transfer material P just after being fixed when the image ratio of a document (transfer material P) is high, the lower curl providing roller pair 55 is pressurized by output from an image ratio detecting means, and the upper curl providing roller pair 56 is released in pressure, so as to provide the lower curl. While, when the image ratio is low, the lower curl providing roller pair 55 is released in pressure, and the upper curl providing roller pair 56 is pressurized, so as to control respective solenoids 59, 60 so as to provide the upper curl.

IPC: B65B55/10
Filed: 1990-11-14
Abstract: PURPOSE:To eliminate cleaning and drying of a packing container and the inside of an equipment after sterilization by sterilizing with air containing sterilizing gas which is obtained by exposing air in a water solution of sterilizer. CONSTITUTION:In a water solution 4 about 35wt.% in total of a relatively large amount of peracetic acid and hydrogen peroxide, a relatively small amount of air is exposed by means of an air diffuser 8 made of glass beads by which bubbles are relatively fine, so that such air is obtained as includes sterilizing gas of peracetic acid and hydrogen peroxide of 1000 to 5000PPM in total. This air is introduced for 10 to 30 minutes sealingly to all of hollow packing containers which are supplied into a sterile room in operation of a sterile filling equipment, the sterile room before operation and a sterilizing device and a filling device, whereby a dry sterilization is done. As the sterilizing gas of peracetic acid and hydrogen peroxide little attach to or remain on the packing containers and the inside of the equipment, a conventional dipping cleaning or injection cleaning with sterile cleaning liquid is unnecessary. Instead, the remaining gas can be replaced and removed only by supplying sterile air after the dry sterilization.

Abstract: PROBLEM TO BE SOLVED: To reduce variations in sensitivity and improve the reliability of a detector by providing a lower electrode film, a piezoelectric film and an upper electrode film on a deposition substrate having an opening and a weight section on the lower electrode film in the opening. SOLUTION: A piezoelectric detector is constituted in such a way that a lower electrode film 102, a piezoelectric film 103 and an upper electrode film 104 are successively formed on a single-crystal Si substrate used as a film forming substrate 101. After the films are separately patterned, a mask material 105 is formed on the backside of the substrate 1 and an etching hole is formed by patterning the material 105. In addition, an opening 106 is formed through the substrate 101 by performing an etching process through the etching hole. Finally, a weight section 107 is formed on the lower electrode film 102 through the opening 106. Since the weight section 107 is directly formed on the lower electrode film 102, it is not required to stick the piezoelectric film 103 and the weight section 107. Therefore, the sensitivity variation of the piezoelectric detector can be reduced and the reliability of the detector can be improved.

IPC: G11B19/02
Filed: 1998-10-29
Abstract: PROBLEM TO BE SOLVED: To smoothly eject a disk cartridge by an auto eject mechanism. SOLUTION: The auto eject mechanism 24 of the recording medium loading device 11 consists of a rising part 52 formed on the left end part 14f of the slider 14, a rotor 56 having an eccentric pin 54 that is driven in contact with the rising part 52, and a motor 58 for rotating the rotor 56. In addition, the rising part 52 is situated on the extension obliquely against the insert/eject direction (A, B directions) of the disk cartridge. Consequently, when the eccentric pin 54 pressurizes the rising part 52 of the slider 14 in the eject direction (B direction) through the rotation of the rotor 56, the rising part 52 is imparted by force Fa in the B direction and force Fb in the C direction.
