Title: Discriminating method of lambda-sonde,left and right of which are connected reversely
Inventor: AROISU BAUAA
IPC: F02D41/22
Filed: 1995-07-03
Abstract: PROBLEM TO BE SOLVED: To simplify lambda probes, and to reduce the cost by discriminating the improper interchanged installation of the right and left lambda probes when the lambda signal of the lambda probes attached to cylinder banks whose injection valves are shut off when the lambda probe signal exceeds or falls below the threshold value set at the shut-off time of the injection valve. SOLUTION: An injection valve 7 of a left cylinder bank 2 is shut off, and an injection valve 8 of a right cylinder bank 4 injects a fuel. Right and left lambda probes 1, 5 are improperly interchanging-installed. That is, both lambda probes 1, 5 are across each other and improperly connected to both cylinder banks 2, 4. The lambda sonde signal U1 of the lambda probe 1 connected to the right cylinder bank 4 in which the fuel is improperly injected though the lambda probe is attached to the shut-off cylinder bank 2, exceeds the threshold S at the end of the shut-off time of the fuel injection valve 7, and the improper connection of the right and left lambda probes 1 and 5 can be identified thereby.

Title: Picture reader
Inventor: SUGAWA HIROYA
IPC: G06T1/00
Filed: 1988-07-05
Abstract: PURPOSE:To attain proper density setting over the entire picture area by designating the automatic density mode or manual density mode and the density level in the manual density mode corresponding to the designated small area respectively. CONSTITUTION:When the automatic density mode is set, a preliminary scanning is executed prior to the main scanning, the optimum value of a binarization threshold level is calculated based on a detected digital picture data and a small area designated in response to the area designation signal is distinguished from other area. Then while an optional small area is designated, when any density mode is designated, the designated density mode is stored corresponding to the small area and a threshold level data for binarization designated in the density mode is stored corresponding to the small area. Moreover, the preliminary scanning and the main scanning are executed based on the stored data group. Thus, even when an original background partially differs or an extreme density difference exists in an original, the optimum threshold level is set to each respective part.

Title: Eliminator for attachment on belt surface
Inventor: SATO JUNICHI
IPC: B65G21/20
Filed: 1985-07-31
Abstract: PURPOSE:To prevent accumulation and drop of powder attached on a belt behind drop preventing plates by directing the apex of the drop preventing plates formed substantially in a V shape on the rear surface of the lower portion of a chute oppositely to the advancing direction of the belt and defining a clearance between the extreme ends of the respective drop preventing plates at the central portion of the belt. CONSTITUTION:A chute 1 for transfer to a belt conveyer is provided at the back thereof with drop preventing plates 3, 3' formed substantially in a V shape and fixed to side drop preventing plates 2, 2'. The extreme ends (that is extreme ends 3-a, 3'-a of the opening portion of the V shape) of the drop preventing plates 3, 3' define a clearance therebetween, so that, after powder attached on the belt 9 is scraped by resilient plates 8 mounted to the lower portions of the drop preventing plates 3, 3', the powder can smoothly flow in the advancing direction of the belt 9. The existence of this clearance avoids accumulation and drop of the scraped powder behind the drop preventing plates 3, preventing meandering of the belt 9 and damage to the edge of the belt 9.

IPC: H01R33/76
Filed: 1999-06-15
Abstract: PROBLEM TO BE SOLVED: To provide a small-size ZIF(zero insertion force) type socket having such durability as to withstand a large number of shifts of a slider. SOLUTION: This ZIF type IC socket comprises a base housing assembly 10 housing a large number of contacts, and a cover housing assembly 40 slidable on the base housing assembly 10. Tool insertion holes 65, 85 are respectively formed in a metal support plate 60 of the base housing assembly 10 and a metal support plate 80 of the cover housing assembly 40. By inserting a plate- like tool 99 through the tool insertion holes 65, 85 and rotating the tool 99, the cover housing assembly 40 is relatively moved. Because application points of the tool insertion holes 65, 85 abutted on the tool 99 are arcuate projecting parts 75, 76, 95, 96, force from the tool 99 can be transmitted to the base housing assembly 10 and the cover housing assembly 40 without causing a recess, a break or the like in the tool insertion holes 65, 85. Accordingly, the ZIF type IC socket has high durability.
