Title: Image scanning recorder
Inventor: IWASA HIROSHI
IPC: H04N1/23
Filed: 1991-11-08
Abstract: PURPOSE:To lower a cost of an image scanning recorder as a whole and reduce a size of a recording head containing an optical system by a method wherein a plurality of light sources are disposed in a two-dimensional manner so as to meet a predetermined geometric relation. CONSTITUTION:Ten laser light beams LB1-LB10 emitted from an optical beam generation part 2 through an aperture plate 3 at a first beam pitch P1 enter a first reduction lens system 4 consisting of a first lens 4a, mirrors M1, M2, and an objective lens 4b. As a result, the beam pitch of 10 beams LB1-LB10 is reduced to a second beam pitch p2 (<p1) through the lens 4a and the lens 4b. Furthermore, the beams LB1-LB10 emitted from the lens system 4 enter a zoom lens 5. As a result, the beam pitch is reduced to a third beam pitch p3 (<p2). After that, the beams LB1-LB10 enter a second reduction system 6, thereafter being condensed on a photosensitive material 10a as fine light spots having a fourth pitch p4 (<p3).

Title: Purification of ethanol
Inventor: SAITOU TOSHINORI
IPC: C07B63/00
Filed: 1996-11-18
Abstract: PROBLEM TO BE SOLVED: To simply obtain ethanol having high quality at a low operational cost without using various distilling columns and chemicals, expensive adsorbers and catalysts, etc., and requiring no installations for waste water, high voltages, etc. SOLUTION: This purification of crude aqueous ethanol solution is to separate ethanol by a pervaporation-membrane separation through a hydrophobic high molecular membrane. The hydrophobic high molecular membrane is from, e.g. a silicon resin such as polydimethylsiloxane, a polyolefin resin such as polyethylene, a fluorine resin, etc., and has >=90 deg. contact angle with water (at normal temperature). As the separating operation is accompanied with a phase change (liquid-vapor), it is necessary to heat a supplying liquid and the heating temperature is brought to be 0-150 deg.C, preferably 20-120 deg.C from the stand point of heat resistance of the high molecular membrane. The operational pressure is brought to be 0-10kg-cm<2> G, preferably 0-5kg/cm<2> G to hold a liquid phase in the feed side. The permeated side is better in a reduced pressure and kept at 0-760mmHg, preferably at 10-200mmHg.

Title: Cross-sectional structure of rocker
Inventor: NOTO KATSUNORI
IPC: B62D25/20
Filed: 1999-11-11
Abstract: PROBLEM TO BE SOLVED: To provide cross-sectional structure of a rocker suppressing the cross- sectional deformation of the rocker without increasing the number of part items. SOLUTION: In the cross section of the rocker 10 composed of a rocker outer 14 and a rocker inner 16, a front pillar inner 20 is disposed linearly, that is, obliquely, from an upper joint part 22 toward a lower joint part 24 and provided with a recessed part 26 at a part thereof. Accordingly, in the case of force F being applied downward from the joint part 22 in a head-on collision of a vehicle, since the horizontal section of the front pillar inner 20 is approximately U-shaped at an input part, rigidity is improved to support the force F. The cross-sectional deformation of the rocker 10 can thereby be suppressed without increasing the number of part items.

Title: Cad plotting system
Inventor: MATSUI MASASHI
IPC: G06F17/50
Filed: 1987-12-21
Abstract: PURPOSE:To prevent eye fatigue and the weakening of eyesight by displaying a warning for a resting time on the display device of a CAD terminal when plotting work time or graphic work quantity exceeds a certain value. CONSTITUTION:When a CAD operator inputs a graphic from a graphic inputting part 1, the input number of times inputted by an input frequency aggregation means 2 equipped in a computer are accumulated. A maximum input frequency setting means 3 which can arbitrarily set input times previously able to input is equipped in the computer. The input number of the times of the CAD operator accumulated by the input frequency aggregation means 2 and the inputtable frequency set by the maximum input frequency setting means 3 are collated by an input frequency collation means 4, when the input number of the times of the CAD operator exceeds the inputtable frequency, a resting time is displayed in the resting time instruction part 5 of the CAD terminal. When a CAD operatable time is previously set in the computer, a resting time control by a working time is possible. Thus, even fatigue and the weakening of eyesight can be prevented.
