Title: Clutch used as constitutional element of driving line for automobile
Inventor: JOSLIN MARK T
IPC: F16D25/0638
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To provide multi-friction plate clutches and a working device, which are provided with an internal reaction circuit, and are arranged in parallel over a long member functioning as a return circuit of reaction. SOLUTION: A clutch assembly 120B disposed in the inside of the driving line 20 of an automobile, is provided with an internal reaction circuit. The clutch assembly 120B is disposed to a place adjacent to a working device assembly, and is provided with a multi-disc friction clutch which selectively applies force to a friction clutch so as to allow torque to be selectively transferred. A clutch constituting element is interposed between stoppers fixed onto a long member functioning as a reaction member which restrains a reaction from a clutch working device by itself. The clutch can be applied to the constituting element of the driving line of an automobile such as an axle 38 of a rear wheel side (a second), and in this case, the clutch is disposed in a paired shape so as to allow control force supplied to each axle to be independently controlled.

Title: Pressure sensitive type input device
Inventor: ABE HIROSHI
IPC: G06F3/047
Filed: 1991-04-23
Abstract: PURPOSE:To enable an operator to surely operate a switch panel without recognizing it with naked eyes at the time of operation by recognizing simultaneous depression of plural positions on the switch panel to execute a corresponding instruction input processing. CONSTITUTION:When a switch panel 1 where many pressure-sensitive switches are distributed like a face is depressed, the depression position is detected by a depression position detecting part 4. If plural positions are simultaneously depressed, a depression state recognizing part 12 recognizes the number of depression positions, and an operation control part 11 performs the corresponding instruction input processing. For example, when the switch panel is so depressed that the depression position is moved in a certain direction, the instruction input processing corresponding to this movement direction is performed. Thus, operator's will is accurately transmitted to execute a certain instruction even if the depression position is not accurate.

IPC: F04D29/12
Filed: 1984-06-11
Abstract: PURPOSE:To reduce the squeak due to the sliding between a floating seat and a seal ring, abrasion of the both, and the roughening of the surfaces, by forming a seal box by fitting a cylindrical ring having water passing windows at the same position to a mechanical slidable surface, onto a shock absorbing rubber. CONSTITUTION:When a pump is driven, a portion of circulating water passes through the rear surface of a vane wheel 23 and two water passing windows 18 of a cylindrical ring 19 which are arranged in the opposite directions at the same position to a mechanical slidable surface 17 and beats the mechanical slidable surface 17, and enters into the cylindrical ring 19 and further enters into a seal box 16 constituted by fitting a floating seat 15 onto a buffer rubber 14 installed water-tightly, and is introduced into a suction passage, passing through the water passing hole 25 of the vane wheel 23. In this case, since the circulating water supplied from the above-discribed circulating-water passage beats the mechanical slidable surface 17 from the vicinity, air foams are collapsed and discharged into the suction passage of the vane wheel 23, and the heat due to the sliding of the mechanical seal is perfectly radiated by the circulating water. Therefore, the abrasion between the floating seat 15 and a seal ring 20 can be reduced.

Title: Small-sized zoom lens
Inventor: NAKAYAMA HIROKI
IPC: G02B15/16
Filed: 1984-06-11
Abstract: PURPOSE:To simplify the zoom lens mechanically, to shorten the overall length of the lens, and easily to obtain a specific power variation ratio by increasing the image forming operation of both 2nd and the 3rd lens groups when moving the 1st and the 3rd lens to the object side for power variation to a zoom position while the 2nd lens group is fixed. CONSTITUTION:The 1st, the 2nd, and the 3rd lens groups are denoted as I, II, and III and movement states during power variation are shown by arrows. Two of the three lens groups i.e. the 1st and the 3rd lens groups are moved for power variation while the 2nd lens group which includes a stop frequently is fixed, simplifying the mechanism. When power variation from the wide-angle end to the zoom position of the telephoto end is performed, the lateral power beta2 of the 2nd lens group and the lateral power beta3 of the 3rd group are increased continuously, improving the efficiency of the power variation. Further, the lens is so constituted that the composite refractive index of the 2nd and the 3rd lens groups is negative and the negative refracting power increases gradually according to the power variation. Consequently, a specific power variation rate is obtained efficiently with the small movement quantities of the lens groups.

Title: Image projection method and exposure method of contact hole using this method
Inventor: KAWASHIMA MIYOKO
IPC: G03F1/00
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To make it possible to optimize an effective light source and to improve both of a contrast and depth by irradiating fine grid-like patterns having a specific pitch with light forming the effective light source of a rectangular annular shape constituting a region intersecting with the pupil. SOLUTION: When a contact hole array is irradiated with the rectangular annular effective light source, a pair of zero order light and first order light is made incident on a position symmetrical with respect to the Kx and Ky axes on the pupil. In such a case, there is no degradation in the contrast by defocusing. The pitch turns to s1=1/(4k1) with respect to the two-dimensional periodic contact hole array of 2k1(λ/NA) and s2 is determined according to contrast defocusing characteristics. Namely, s2 is determined by the required contrast at the required depth. The contrast defocusing characteristics which are nearly the same as quadrupole illumination consisting of a circular shape of the same radius as s2 are obtained and the ratio of the area occupying the pupil of the effective light source increases exceedingly.  If s2=0.1 or below is attained, there is substantially no degradation in the contrast.

Therefore, the necessity of delaying the timing of paper feeding from a paper feeding body 1 is obviated, and the signal communication with the body 1 is omitted.
