Title: Reciprocating type electric razor
Inventor: HIRATA HARUNOBU
IPC: B26B19/28
Filed: 1992-06-23
Abstract: PURPOSE:To reduce a vibration generated at the time of driving an inner blade for reciprocating motion by providing a leaf spring with one end fastened to a drive section for causing the inner blade to reciprocate, and a dynamic vibration reducer comprising a weight fitted to the other end of the leaf spring. CONSTITUTION:A reciprocating electric razor 10 is constituted of an outer blade 1, an inner blade 2 nutating along the inner side of the outer blade 1, a drive section 3 for causing the inner blade 2 to reciprocate, and a body 4 to house the drive section 3. Also, a dynamic vibration reducer 7 comprising a leaf spring 5 and a weight 6 fitted to one end thereof, is fastened to the side of a motor 8 via a fastener 11. According to this construction, the amplitude of the weight 6 can be made large, due to the relatively small attenuation of the spring 5, and a vibration generated due to the reciprocating motion of the inner blade 2 can be reduced.

Title: Improvement of soft ground
Inventor: FURUIKE YOSHIO
IPC: E02D3/12
Filed: 1984-08-08
Abstract: PURPOSE:To easily perform improving work of the ground by a method in which an inner tube with many holes in its body is driven into an outer tube with many holes, driven into the ground to be improved, and while applying DC voltage between the inner and outer tubes, a chemical grout is injected. CONSTITUTION:An outer tube 1 having many holes 2 in its body is driven into the ground 3 to be improved, and an inner tube having many holes 5 in its body is driven into the center of the tube 1. DC voltage is applied between the outer tube 1 of negative polarity and the inner tube 4 of positive polarity by a rectifier to generate an electric permeation phenomenon in the ground 3 between the outer and inner tubes 1 and 4. When a chemical grout is injected from the upper part of the inner tube 4 into the portion where the electrical permeation phenomenon occurs, the chemical grout goes out from the holes 5 of the inner tube 4 and permeates into the inner wall of the outer tube 1, where chemical reactions and ionic reactions take place to promote the solidification of the ground 3.

Abstract: PURPOSE:To considerably reduce the production process of a liquid crystal panel, to reduce the cost, and to stabilize a product by filling up a sealed space with a proper amount of liquid crystal dropped to the sealed space simultaneously with pressure-contacting between liquid crystal substrates by an exhausting means. CONSTITUTION:A proper amount of liquid crystal 3 is dropped to an upper face 1a, which is provided with an electrode pattern and is surrounded with a sealing adhesive 2 provided in the vicinity of the periphery of this upper face 1a, of a liquid crystal substrate 1, and the other liquid crystal substrate 6 is put on this substrate 1, and air is exhausted to not only stick both liquid crystal substrates 1 and 6 to each other but also fill up the sealed space with liquid crystal at a time. That is, liquid crystal 3 dropped to the upper face 1a of the substrate 1 is pressed by the substrate 6 and is expanded in all directions at the time of putting the substrate 6 on the substrate 1 and is finally extended to almost all areas between both liquid crystal substrates by exhausting from a break of the sealing adhesive 2, and both liquid crystal substrates are stuck to each other by the sealing adhesive 2 simultaneously.

Title: Manufacture of semiconductor device
Inventor: HORIBA SHINICHI
IPC: H01L21/027
Filed: 1988-07-01
Abstract: PURPOSE:To minimize the alignment errors by a method wherein the marks on a semiconductor substrate both in X and Y directions are formed respectively on the X and Y axes assuming the center of the exposure region as an origin to measure the alignment errors in respective X and Y directions of an aligner. CONSTITUTION:Marks 101,102 to measure the alignment errors in respective X and Y directions are arranged on the central position of an exposure region. After exposure and development, the overlapped errors in the marks 101, 102 are measured to input the data in the aligner as the alignment correction amount for making the alignment errors + or -0. Since the conventional marks are arranged on the peripheral parts of the exposure region both in X and Y directions, even if the alignment errors in the position are corrected to + or -0 both in X and Y directions, the other exposure regions are subjected to notable effect of lens distortion resulting in new alignment errors. However, in this invention, said marks 101, 102 being arranged on the central position of the exposure region, the alignment errors due to the lens distortion in the other exposure regions can be restricted to the minimum.

IPC: E01C11/24
Filed: 1994-06-14
Abstract: PURPOSE:To embody an elastic porous road surface pavement which withstands a heavy load and which is less strict in construction conditions. CONSTITUTION:Large-sized aggregates, small-sized aggregates and small rubber pieces or powder are bonded with polyurethane. A stone material whose grain size ranges from 4 to 20mm, is used for the large-sized aggregates, thereby forming porosity therewith. One liquid water content curing type is suitable as the polyurethane. The curing time ranges from 30 to 48 hours. Preferably, it should range from 6 to 24 hours. More particularly, the content of isocyanate is pref. below 20wt.% This prevents the generation of air foam by carbon dioxide. The aggregates withstands the application of a heavy load while elasticity is provided. During freezing time, they are subjected to deformation caused by the load of a vehicle while braking ice. The pavement has water permability thereby producing no puddles on the pavement.

Abstract: PURPOSE:To easily form a plating layer having different concentration gradient and excellent corrosion resistance, in plating the surface of a steel sheet in a Fe-Zn plating bath, by continuously plating the surface with different current densities. CONSTITUTION:A sulfate plating bath containing Zn and Fe ions at the weight ratio of 0.02-0.90 and the total of Zn and Fe sulfates above 100g/l and up to their solubility limits is supplied to continual several plating cells 6-10 under the condition of pH; 0.8-2.3 and the temperature of liquid; 40-80 deg.C from a tank 1 by a pump. An electric current is applied to a steel sheet 3 to be plated between anodes A1-A5, while the steel sheet 3 is being carried from the plating cell 6-10. The anodes A1-A5 hence gradually reduce their surface areas, and current densities are gradually made larger from the anode A1-A5 in inverse proportion to the surface areas, so that an Fe-Zn plating layer having such gradient in the concentration of the two metals that Zn content is gradually reduced from 98%-5% is formed. Consequently, a coated steel sheet having the plating layer excellent in corrosion resistance is obtained.

Title: Exposing device for forming fluorescent screen
Inventor: KOBAYASHI KENICHI
IPC: H01J9/227
Filed: 1982-09-25
Abstract: PURPOSE:To make the inclination of a dot trio coincide with that of a beam trio and prevent deterioration by arranging a negative meniscus lens between a landing correction lens and an exposing light source and decreasing the inclination of the dot trio when it is larger than that of the beam trio. CONSTITUTION:The position of a light source is shifted to 32-a, 32-b, 32-c in response to the exposure of R, G, B and a negative meniscus lens is used in a fixed state, but the inclination of a dot is decreased due to its aberration. The inclination of the dot can be made to coincide with that of a beam by selecting an adequate shape of the lens. In addition, the spherical aberration of the lens can be made small for the exposure of a green dot, thus giving no influence on landing. For the exposure of a side dot, if the position of a side light source is separated from the position of a center light source by a quantity to negate the equivalent shift to the lateral magnifying power, the delta-DELTAs correction in the horizontal direction can be applied.
