Title: Plunger mechanism for timing chain
Inventor: SUMINO KOSHIRO
IPC: F16H7/08
Filed: 1995-08-29
Abstract: PROBLEM TO BE SOLVED: To prevent a timing chain from being slack or tensed excessively and the occurrence of friction noises or impact noises by setting the rotation center of a cam at the position shifted to a non-return tooth from right up the sub-tooth. SOLUTION: A cam member 53 is set at the shifted position to the front non-return tooth 53a of a sub-tooth 53b in the straight direction which connects a rotation center CP with the non-return tooth 53a or the sub-tooth 53b, or in a to-and-fro direction: the rotation center CP is set at the position which is offset by a specified distance in front of the sub-tooth 53b in a horizontal direction. The offset amount Of from the sub-tooth 53b is adjusted according to the amount of backlash. A rotation radius (r) is adjusted and the distance to the position after the backlash can be set at the value required by an engine. Since the timing chain is always pressed with a suitable backlash, friction noises made when the chain is under excessive tension and impact noises made when it is slack can be prevented.

IPC: G01N35/10
Filed: 1987-09-04
Abstract: PURPOSE:To enable various inspections by commonly using a piece of probe while cleaning the same at the time of dispensing samples and reagents. CONSTITUTION:The common probe 23 is positioned over the sample 4' on a sample cassette 3 by swiveling a dispensing arm 22 and the sample is sucked by vertically moving the probe 23. The arm 22 is then swiveled to set the probe 23 over the reaction cell in the dispensing position C of a reaction desk 1 and the required volume of the sucked sample is dispensed into the reaction cell. The probe 23 is thereafter positioned over a common cleaning pool 24 where the probe 23 is lowered and the inside and outside walls thereof are cleaned. The probe 23 after the cleaning is swiveled to the position 6' above a reagent cassette 5 where a 1st reagent 6a is sucked. After the reagent 6a is dispensed into the reaction cell into which the sample is dispensed in the position D of the desk, the probe 23 is similarly cleaned. The probe is further swiveled to the position 6' on the cassette 5 and the 2nd reagent 6b previously moved to the position 6' is sucked. The reagent 6b is dispensed into the reaction cell into which the reagent 6a is dispensed in the position D. The various tests are thus enabled.

Title: Unmanned carrier
Inventor: KUREBAYASHI SUSUMU
IPC: G05D1/12
Filed: 1989-08-29
Abstract: PURPOSE:To reduce the travel space width of an unmanned carrier at a curve part of a traveling course by securing the interlock between the drive wheels and te follower wheels of the carrier and a steering means which is controlled based on the sense signal of a guide means. CONSTITUTION:A servo motor 267 functions to steer two drive wheels 205 and two follower wheels 207. The motor 267 is connected to a travel control part and controlled by the signals received from the sensors (pick-up coils) 303 and 304 which detects a magnetic field produced by the current flowing to a buried guide line 301. Both sensors 303 and 304 detect the position errors (X, Y) of an unmanned carrier 201 against the line 301 based on the difference of voltage induced at the sensors 303 and 304. The detection signals received from both sensors 303 and 304 are inputted to the travel control part. Thus the travel part controls the motor 267 in the direction where the position error of the carrier 20 is corrected based on those detection signals. As a result, the travel space width is reduced at a curve part of a driving course. Furthermore plural carriers 20 can travel with satisfactory approximation secured with each other among them.

IPC: B21B1/08
Filed: 1986-09-22
Abstract: PURPOSE:To produce shapes changing continuously or intermittently a web width only by rolling by controlling the cross angle, gap and web rolling reduction of rolls according to the desired web width with a pair of upper and lower cross helical rolls. CONSTITUTION:Peripheral faces 13 of the cross helical rolls 11 roll down the web 4 of an inlet side rolling stock 1 having an H section from above and below and exert the thrust force Fa in the direction of an angle alpha with the X-axis to the web 4 in rolling flanged shapes. As a result, the component of force FL of the thrust force Fa retracts the rolling stock 1 in the progressing direction and the component of force Fc of the thrust force Fa elongates the web 4 in the transverse direction. The outside peripheral faces 15 of the cross helical rolls 11 contact the inside side faces of flanges 5 and act as the force to force expand the inside side faces of the flanges in the transverse direction of the web. The shapes having the continuously or intermittently changing web width are thus produced only by rolling.
