Title: Printing head
Inventor: ASANO AKIRA
IPC: B41J2/28
Filed: 1987-09-25
Abstract: PURPOSE:To obtain a release-type printing head having excellent printing characteristics and capable of high-speed printing, by providing a first fulcrum for deflecting a leaf spring by a magnetix flux of a permanent magnet and a second fulcrum for adjusting an impact force of the leaf spring. CONSTITUTION:When a coil 5 around a core 3 is excited and an armature 11 is released from attraction, a wire 13 collides against a platen 20. By an impact force Fimp generated at this moment, a moment Mimp around an impact center G in the armature 11 is generated, as shown in Fig. (b), and the armature 11 tends to rotate about the impact center G. At this moment, a leaf spring 10 is restrained from moving upward, by a pressing force fsb exerted by an auxiliary spring 15 (second fulcrum). A downward reaction of the leaf spring 10 generated subsequently is restrained, this time, by a protrusion 9a (first fulcrum). Namely, the leaf spring 10 is restrained from motion on both the upper and lower sides by the impact center G, the auxiliary spring 15 and the protrusion 9a, so that the leaf spring 10 is restrained from being vibrated by the impact force Fimp.

Title: Production of liquid crystal device
Inventor: OGAWA HIROSHI
IPC: G02F1/1333
Filed: 1996-09-10
Abstract: PROBLEM TO BE SOLVED: To provide a production method of a light scattering type liquid crystal device having a light-controlling layer of a liquid crystal and a transparent solid material, by which reflection of active rays on the interface between a substrate or a scattering layer and a light-shielding material such as a black matrix which partly cuts the active rays is prevented, and by which a process to wipe a liquid on the substrate can be omitted.

IPC: B63B5/24
Filed: 1993-08-30
Abstract: PURPOSE:To improve the strength of the broadside part of a blow-molded boat without increasing a material cost and the weight of a ship hull and to prevent the occurrence of a dent and formation of a hole in the broadside part. CONSTITUTION:A blow-molded boat comprises a lower ship hull 12 containing a boat bottom part 11 and forming the lower part of a ship hull; and an upper ship hull 13 assembled to the lower ship hull 12 and forming the upper part of the ship hull. Both the lower and upper ship hulls 12 and 13 are a blow- molded boat consisting of a hollow body having a double wall structure produced by blow-molding. Since a ratio (H1/Y) between the height and the lateral width of the lower ship hull 12 is low, the thickness of each part is uniformized and the thickness of the outer wall of a broadside part is prevented from being especially decreased. When the lower and upper ship hulls 12 and 13 are assembled together, the inner and outer wall of the central area of the broadside part are brought into a state to be interconnected through two plates (a) and (b) and the part is reinforced.

Title: Method and device for selective etching
Inventor: OKUDAIRA HIDEKAZU
IPC: H01L21/316
Filed: 1991-09-19
Abstract: PURPOSE:To provide a method of etching selectively a material having a small photo absorption coefficient between a plurality of materials, which are different from each other in photo absorption coefficient. CONSTITUTION:In a dry etching of a sample consisting of a plurality of materials, which are different from each other in light absorptive characteristics, the material having a small photo absorption coefficient is selectively etched to the material having a large photo absorption coefficient by emitting light 4 capable of absorbing GaAs only, for example. By the light emission, a light CVD reaction, a light oxidation reaction and a photodissociation is caused only in the surface, such as 2, of the material having a large photo absorption coefficient and an etching rate on the material, such as 1, having a large photo absorption coefficient is made small. Thereby, an etching of the material only, such as 1, having a small photo absorption coefficient becomes possible.

Title: Laminated heat exchanger
Inventor: UEDA HIRONOBU
IPC: F28D9/00
Filed: 1991-09-19
Abstract: PURPOSE:To simplify a heat exchanger and a connecting facility and to reduce a cost by altering opening areas of pores of a heat transfer plate disposed in a spacer passage at each fluid passage when spacers and the plates are alternately laminated or varying the thickness of the plate of the fluid passage. CONSTITUTION:Heat is transferred from high pressure gas 7 flowing in a high pressure gas passage partitioned by a heat transfer plate 1 and a spacer 2 to the plate 1, and transferred to low pressure gas 8 flowing oppositely to a low pressure gas passage through the plate 1 to be heat exchanged. Since gas pressure of the atmospheric pressure or more is loaded in the passage of the plate 1 and the spacer 2, both are connected with adhesive material such as adhesive or by diffusion connecting. A pressurizing unit can be simplified by reducing the sectional diameter of a laminate as much as possible. It is necessary to uniformly heat the laminate as the condition for desirably connecting the plate 1 to the spacer 2, and when a heat exchanger can be simplified, heat storage amount of the laminate is reduced, and hence the cost of electric energy of an apparatus for supplying heat can be reduced.

Title: Semiconductor nonvolatile memory and manufacture thereof
Inventor: OGURA KIYONORI
IPC: H01L29/792
Filed: 1990-09-10
Abstract: PURPOSE:To accurately read data and to hold it by providing a low concentration opposite conductivity type layer on one conductivity type semiconductor layer, forming a memory cell in which a floating gate becomes neutral in a depression type or, if it is charged, in an enhancement type. CONSTITUTION:A control gate electrode 5 is irradiated with an ultraviolet ray to set a memory state to '1'. In this case, depression type characteristic as shown by symbol A of a graph is obtained. A writing voltage Vpp is applied to an electrode 5 and a drain layer 8 to set a memory state to '0'. In this case, it is shifted to an enhancement type as shown by symbol B. Since '0', '1' can be read even if the electrode 5 is set to the same potential as that of a substrate voltage, if the electrode 5 is disconnected from a power source voltage, the potential of the voltage 5 is not raised, a memory cell is not turned ON when the data '0' is read, and yet the data ''l'' is normally held. Since a low concentration opposite conductivity type diffused layer 6 is formed on a semiconductor layer 1 by increasing high concentration opposite conductivity type diffused layers 7, 8, an ion implanting step is omitted, and a device is formed by normal steps.
