Title: Wafer chuck
Inventor: YABU SHUICHI
IPC: G03F7/20
Filed: 1984-09-20
Abstract: PURPOSE:To retain a wafer horizontally without interposing dust by a method wherein one of two retaining parts is vertically moved while the recesses and projections of the wafer are being measured by the non-contact gap sensor located at the center part of a chuck. CONSTITUTION:The groove empty space located between the first retaining part 6 and the second retaining part 7 is turned to negative pressure, and a wafer 1 is attracted thereon. When the retaining part 7 is moved vertically by expanding and contacting a piezoelectric stack 8, the wafer 1 is deformed into recessed or projected form. At this time, the gap (x) located between a sensor 10 and the wafer 1 is measured by a non-contact gap sensor 10, and the amount of expansion and contraction of the piezoelectric stack 8 is controlled. As a result, the wafer 1 is retained horizontally without being subjected to the influence of dust.

Title: Stone packed cage revetment wall for river
Inventor: SHIRAI JUNICHI
IPC: E02D17/20
Filed: 1996-07-05
Abstract: PROBLEM TO BE SOLVED: To improve water control effects by setting stone packed cages with stones packed inside in row left and right along the river, dislocating fore-and-aft a front position of the stone packed cages at a portion of the revetment wall lying adjacent to a water stream in a form of a plurality of steps superimposed vertically for placing unevenness on the wall face. SOLUTION: The position of a front face 5 of stone packed cages 2 is dislocated fore-and-aft and a revetment wall 1A is arranged in juxtaposed relation for forming recess portions 6 and projection portions 7 on the wall face. At that time, the uneven portions 6, 7 lying adjacent to a stream of water create a good water control effects such as a deviation of the water flowing direction and a relaxation of a stream of water. In addition, the water stream 4 hits against the projection portions 7 to thereby be in turbulence and also take in and stirring air so that good purifying effects can be obtained. In particular, the water stream 4 hitting against the wall face 7 retains rapid flow and a part thereof comes into an inner portion of the stone packed cages 2 and passes therethrough, thus a relaxation of the flow speed results in decelerating effects.  As such, the wall face recess portions 6 lead to be a living area or refuge area for a waterplant and fish, thereby ensuring an excellent environment of a living thing, and performing an effect of nature conservation.

IPC: A23G9/08
Filed: 1986-08-22
Abstract: PURPOSE:To adjust hardness of a product to a desired value, stopping cooling and stirring when the output torque value of a stirring motor calculated from voltage and frequency of an electric power source and current value flowing through the motor exceeds the set value.

Title: Variable wavelength laser
Inventor: SUZUKI TAKASHI
IPC: H01S3/107
Filed: 1993-08-09
Abstract: PURPOSE:To vary the wavelength of output light by varying the level of voltage being applied to an electrooptic deflector by a variable voltage applying means. CONSTITUTION:A mirror M2 is arranged such that the normal to the reflective surface thereof intersects a light beam entering an EO deflector 30 from a laser medium 1 at an angle of 8 deg., for example. Only a light deflected by 8 deg. through the EO deflector 30 enters the mirror M2 normally and reflected to advance the resonance optical path reversely thus meeting the resonance conditions. Consequently, only a light having specific wavelength causes laser oscillation and outputted from he mirror M2 as a laser light. When a voltage controller 22 is operated according to formula I to vary the electric field being applied to the EO deflector 30, the variation of internal refractive index of each prism 31, 32 varies thus varying the relationship between wavelength and deflection angle. Consequently, the wavelength of output laser can be selected easily by simply operating the voltage controller 22. In the formula, nE represents the wavelength dependency and the deflection angle theta=theta(lambda) varies depending on the wavelength.

Title: Electrophotographic photoeceptor
Inventor: KIMURA MICHIO
IPC: G03G5/05
Filed: 1994-07-29
Abstract: PURPOSE:To obtain an electrophotographic photoreceptor excellent in cracking resistance without deteriorating electrophotographic characteristics by incorporating polycarbonate resin into an electric charge transfer layer and specifying the glass transition temp. of this layer. CONSTITUTION:When an electric charge generating layer and an electric charge transferring layer are formed on a substrate to obtain an electrophotographic photoreceptor, polycarbonate resin is incorporated into the electric charge transfer layer and the glass transition temp. of this layer is regulated to 70-85 deg.C. In the case of <70 deg.C, trouble such as the filming of a toner is liable to occur in a small-sized electrophotographic copying device in which the service temp. of the photoreceptor is increased to 50-60 deg.C. In the case of >85 deg.C, the photoreceptor is liable to crack at the time of repetitive use. The reason why the polycarbonate resin is used as the binder of the electric charge transfer layer is that only this resin is favorable from the viewpoint of the wear and moisture resistances of the electric charge transfer layer and the sticking of a toner in practical use.
