IPC: B22D5/04
Filed: 1992-11-11
Abstract: PURPOSE:To make dividing easy with a tool like a hammer, to improve efficiency for production and to facilitate packing for shipment and transportation by forming grooves faced oppositely on the lower surface and the upper surface of a metal. CONSTITUTION:Two sets of groove 2 are formed on the metal 1, which can divide the metal 1 into three pieces of metal 1a, 1b, 1c. The number of the grooves 2 is made arbitrary as necessary. Also, the number of the grooves 2, namely, not only the weight of each piece of the metal 1a, 1b, 1c but the size of the metal 1 may be produced for an arbitrary size as necessary. The metal 1 may easily be divided into small pieces with a hammer, etc., by a user when used; also, a simple packing such as bundling the stacked pieces of metal 1 is sufficient; and an economic effect is expected.

Title: Adjusting arrangement of beta 2-subunit of neuron nicotinic acetylcholine receptor and genome dna fragment containing arrangement coding this and transgenic animal prepared by using these fragments or mutant fragment
Inventor: CHANGEUX JEAN-PIERRE
IPC: C12Q1/68
Filed: 1995-12-14
Abstract: Several genes encoding subunits of the neuronal nicotinic acetylcholine receptors have been cloned and regulatory elements involved in the transcription of the  alpha :2 and  alpha :7-subunit genes have been described. Yet, the detailed mechanisms governing the neuron-specific transcription and the spatio-temporal expression pattern of these genes remain largely uninvestigated. The  beta 2-subunit is the most widely expressed neuronal nicotinic receptors subunit in the nervous system. We have studied the structural and regulatory properties of the 5' sequence of this gene. A fragment of 1163 bp of upstream sequence is sufficient to drive the cell-specific transcription of a reporter gene in both transient transfection assays and in transgenic mice. Deletion analysis and site-directed mutagenesis of this promoter reveal two negative and one positive element. The positively acting sequence includes one functional E-box. One of the repressor elements is located in the transcribed region and is the NRSE/RE1 sequence already described in promoters of neuronal genes.

Title: Plate bending method
Inventor: OTA TAKAHIRO
IPC: B21D5/01
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To reduce a man hour by calculating a correction coefficient from a difference between a curvature, in which a tentative curvature after spring back obtained from a constant of a cumulative hardening law constituting formula obtained from a plate bending angle and a yield stress and a Young modulus is pressed to be turned to a prescribed ratio of a target curvature, and a tentative curvature and adopting a corrected curve obtained from a Young modulus and a correction coefficient for the target curvature. SOLUTION: When a tentative curvature calculated for a target curvature in bending a plate 10 is turned to a prescribed ratio, by interrupting bending once with an arithmetic control device, irradiating the plate 10 with laser beam from beam source and conducting image processing to its reflected beam 8 after picking up image, a ratio between a curvature of the plate 10 after spring back and a tentative curvature is made to a correction coefficient. Again bending of the late 10 is started, by obtaining a work hardening constant (n) and a stress constant F so that a measured angle by an inclination meter 7 and a prescribed formula coincides with a calculated bent angle, until a corrected curvature of the plate 10 with deciding a cumulative hardening law constituting formula and introducing a correction coefficient coincides with a target curvature, a slide 4 is descended.  Thus, the need of correction bending is eliminated.

Title: Camera provided with vari-focal lens
Inventor: ISHIBASHI KENJI
IPC: G03B13/36
Filed: 1989-12-18
Abstract: PURPOSE:To allow the intention of a photographer to faithfully reflect on the control of a camera by giving priority to zoom driving based on the operation by the photographer rather than a low control scanning action not based on the operation by the photographer. CONSTITUTION:The camera is so constituted that the low control scanning action is inhibited and the zoom driving is prioritized when a zooming operation is performed in the middle of the low control scanning action where a focus detecting action is performed while a focusing lens LF is driven until it is decided that the focus can be detected at the time of deciding that the focus can not be detected by a focus detection means 4. Therefore, the intention of the photographer faithfully reflects on the control of the camera. When an out-of- focus quantity caused by zooming is calculated and the focusing lens is driven so as to eliminate the out-of-focus quantity at the time of driving a zoom lens, an object distance hardly changes before and after the zoom driving, so that scanning need not be performed again after the zoom driving to an object distance range where scanning has been already performed before zoom driving. Thus, the reliability of the low control scanning action is prevented from being impaired by interposing the zoom driving.

Abstract: PURPOSE:To improve the strength of a die and to reduce its cost by forming a metallic film on an original mold, coating the surface with a plating film, then, pouring molten alloy of the same kind on the plating film. CONSTITUTION:The original mold 1 such as a wooden mold or a plaster mold is formed and a metallic film 2 which is 10mu-1mm in thickness is formed by electrocasting or thermal spraying on its surface. Then, the surface of the metallic film 2 is plated by plated film 3 such as metallic zinc and, after it is dried and cleaned, molten alloy 4 of the same kind with the plated film metal is poured. First, since a plated layer 2 by electrocasting is formed on the surface of the mold 1, a faithful reproduction of the original mold 1 is performed. Since the metallic film 2 and the molten alloy 4 are joined through the plated film 3, the degree of adhesion is elevated. In this way, the strength of the mold is improved and the plated thickness on the metallic film 2 can be thinned and the cost of the mold can be reduced.

Abstract: PURPOSE:To surely prevent a recording medium with a high recording density mode from being loaded to a floppy disk drive FDD with a low recording density mode not compatible with the high recording density mode in error by surely identifying the recording media with the different recording density mode. CONSTITUTION:Interface lines 12a, 12b through which transfer 2-bit recording density mode signals D1, D2 are transferred are provided between a disk drive FDD 10 and a disk controller FDC 11, and when a recording medium with the low recording density mode or the high recording density mode is loaded onto the FDD 10, the recording density mode signals D1, D2 representing a maximum of 4 kinds of the recording density modes are transferred to the FDC 11. Thus, the FDC 11 applies the read/write control to the recording medium with the low recording density mode in addition to the recording medium with the high recording density mode. Thus, an event that the recording medium with the high recording density mode is loaded to the disk drive for the low recording density mode not compatible with the high recording density mode in error and the data on the recording medium is destroyed is prevented.
