Title: Wide-angle zoom lens
Inventor: TAKASE HIROSHI
IPC: G02B13/04
Filed: 1981-05-29
Abstract: PURPOSE:To compensate the deterioration of performance of image formation with a parallel plane, by constituting a system comprising a front group having negative refractive index and a rear group having positive refractive index and limiting the refractive index of lenses constituting the front group through the provision of the parallel plane for automatic focusing at the image side of the rear group. CONSTITUTION:A system has a front groupIhaving negative refractive index consisting of a negative meniscus lens L1, a negative lens L2, a positive lens L3 in the order of an object side, and a rear group II consisting of a positive lens L4, a positive meniscus lens L5, a negative lens L6 and a positive lens L7, and a parallel plane III as a photosplitting element is disposed as the back of the rear group II. In zooming, the movement is made while the interval between the front groupIand the rear group II is changed. To compensate the aberration due to the parallel plane III, the equation of 1.7<n2, and 1.65<n1, n2 is satisfied, where refractive index of the lenses L1, L2 and L3 is respectively n1, n2 and n3. Further, the performance can be increased by giving of limit to 8 numerals.

Title: Manufacture of thin-film transistor
Inventor: NAKAMURA KENICHI
IPC: H01L29/786
Filed: 1991-04-15
Abstract: PURPOSE:To provide good transistor characteristics even if active layers are formed as thin as tens of nanometers in a thin-film polysilicon planar transistor for switching devices or peripheral devices of a liquid crystal display. CONSTITUTION:Sources (4a and 4b) of impurity diffusion are selectively formed on a glass substrate, and a semiconductor layer on the substrate is annealed for crystallization. The impurity is diffused from the sources into the semiconductor layer on the substrate to form source and drain regions 8a and 8b (lightly doped source/drain region in the case of LDD TFT). On the other hand, that region of the semiconductor layer, above which no diffusion source exists, is crystallized to form an undoped active layer 7. According to this method, source and drain regions with uniform impurity concentration even in a semiconductor layer that is as thin as tens of nanometers. As a result, it is possible to provide a polysilicon thin-film transistor (or LDD TFT) having uniform characteristics.

Title: Method for detecting edge of metal plate
Inventor: YAMAZAKI TAKUYA
IPC: G01B17/00
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To accurately measure a position of an edge of a metal plate by disposing the edge at a position between a receiving element for a transmitted wave from an ultrasonic wave transmitting element and a receiving element for a direct wave by using an ultrasonic wave transmitting and receiving element. SOLUTION: A transmitted wave T0 from an ultrasonic wave transmitting element is incident on a steel sheet 3, emitted as a transmitted wave T1 or reflected once or more in therein, emitted as a transmitted wave T2, and incident to an ultrasonic wave receiving element. The transmitted wave is also reflected by an intermediary 6 in the sheet 3, and incident on the receiving element as a fault reflected wave TC. A length of a path of the wave TC is a middle of the lengths of the paths of the waves T1 and T2. Meanwhile, the wave T0 emitted at a position out of the sheet 3 is incident on the receiving element as a direct wave TD. Here, since an intermediary fault is disposed at an indefinite position, the fault reflected wave is received in a non-definite period, but the transmitted and direct waves are received in a definite period synchronously with the transmitted wave.  Accordingly, the edge 31 of the plate 3 can be decided by deciding a position between the transmitted and direct waves based on a specific sequence.

Title: Information recorder
Inventor: YANAGISAWA MINORU
IPC: G11B23/113
Filed: 1987-04-03
Abstract: PURPOSE:To quickly and surely open and close a shutter, by using a spring made of a metal which has at least two points of inflection, at which the metal is bent in different directions, and is bent to have an almost V-shape as a whole in a plane, as a spring to be used for opening and closing the shutter. CONSTITUTION:When a shutter 9 compresses the spring 11 for information recorder of this invention, bending forces applied to the constricted sections 11a and 11b and circular arc section 11c of the spring 11 become opposite in direction to each other between the outside and inside as shown by the arrows, since the spring 11 has points of inflections between the constricted sections 11a and 11b and circular arc section 11c, respectively. Namely, the directions of the bending forces on the outside and inside of the constricted sections 11a and 11b respectively become (e) and (f) and (g) and (h). The directions on the outside and inside of the circular arc section 11c respectively become (i) and (j) and (k) and (l). Thus the directions of the bending forces applied to each part become opposite to each other. The elastic force produced at this section, therefore, acts as if it displaces the metal wire constituting the spring 11 in directions crossing each other at right angles with the points of inflection being fulcra. Thus a strong elastic force can be obtained.

Title: Intake device for internal combustion engine
Inventor: TANAKA KOTARO
IPC: F02B75/02
Filed: 1991-04-15
Abstract: PURPOSE:To prevent the counterflow of mixed gas into an air group intake passage in an intake device in which a mixed gas group intake passage and the air group intake passage communicate with each other. CONSTITUTION:A mixed gas group surge tank 1 is installed on the upstream side of a mixed gas group intake passage 13 in which the top edge of an injector 11 is set midway, and a scavenging surge tank 18 is installed on the upstream side of an air group intake passage 15, and the edge parts in the axial direction are connected through an air intake pipe 20. Even if the blow-back of the mixed gas is generated in the mixed gas group intake passage 13, the generation is suppressed by the mixed gas group surge tank 18. Further, because of the existence of the scavenging surge tank 18, the mixed gas is hardly sucked to the air group intake passage 15 side. Accordingly, the inside of the cylinder can be scavenged only by the air, and the uncombusted gas is prevented from being discharged outside in scavenging.

Abstract: PURPOSE: To obtain a water dispersion type paint having an improved blocking resistance during storage, by a method wherein water-insoluble resin particles are dispersed in an aq. medium, and then the resulting is dispersion is heat-treated or, if necessary, redispersed after the heat treatment.  
     CONSTITUTION: A mixed liquid obtd. by blending water-insoluble resin particles, an additive or an auxiliary and water, is dispersed by using a dispersing device such as a mixer, a disper, a ball mill, a sand mill or an attritor, or by an ultrasonic wave irradiation method, to produce a primary dispersion. The primary dispersion is heated as such, or redispersed after this heat treatment by using the above dispersion method. Alternatively, the primary dispersion is heated while stirring and fluidizing said dispersion by using a mixer or a disper. If necessary, after cooling the resulting dispersion is re-dispersed by using the above dispersion method. This re-dispersion treatment is effective when the dispersoids agglomerate and lump is formed during heating. Said resin particles include these of film-forming resin alone and those of a mixture of said resin, a hardener, a pigment, a catalyst, and other additives.

Filed: 1992-04-06
Abstract: PURPOSE:To obtain a title device which outputs a photocurrent corresponding only to a photoenergy of an input light spot with loss reduced by providing every microimpurity layer with a pair of coupling capacitances. CONSTITUTION:Every distribution capacitance generated by polysilicon layers 32 and 33 piled up on the top face of microimpurity layers 29 is connected between output bonding pads 35 and 34 as the coupling capacitance. Similarly, every distribution capacitance generated by added polysilicon layers 39 and 40 is connected between the output bonding pads 35 and 34 as the coupling capacitance. A photocurrent generated by incidence of a light spot into microimpurity layers is divided according to the capacitance ratio of the distribution capacitance and fetched by the output bonding pads 34 and 35. Since the capacitance ratio is an intrinsic value corresponding to the incidence position of a light spot, it can be sensed by measuring the value of a fetched current.
