Abstract: PURPOSE:To conceal an instruction code read from a ROM by providing a bit converting part in an internal part and converting data from a memory at every bit in a designated way. CONSTITUTION:To the ROM to be used, an instruction word is stored beforehand at every bit for the bit of the instruction code in a form converted by the prescribed pattern of an inversion or noninversion, and an operand code is stored in the form of the correct code. A bit converting part 10 consisting of a latch circuit 1, gate circuits 2-5, EX-OR circuits 6-9 is provided at the routes of internal data buses 200 and 300, and the bit converting part 10 is constituted so as to operate at an instruction code fetch cycle, and so as to conduct at the other cycles. For the bit conversion of the bit converting part 10, by inversely converting the bit conversion at the time of writing to the ROM, the correct instruction code can be obtained at the instruction code fetch cycle, whereas, another person cannot read the instruction code from the ROM itself. Thus, the contents of the ROM can be concealed from the other person.

Abstract: PURPOSE:To prevent a fuse from being cut by mistake in the case it is unnecessary by connecting the node of one side of a transfer gate to an external input terminal, and connecting the node of the other side of the transfer gate to one power supply through a fuse means. CONSTITUTION:When both an ESET termiual 107 and an exclusive terminal for test are turned Low, a two-input NOR 106 becomes a High level, and an N and a P transistors 102 and 103 are turned on.

Filed: 1997-11-25
Abstract: PROBLEM TO BE SOLVED: To always monitor generation of leak from joint, by detecting leakage of gas containing iodine from color change of adsorbent changing the color by chemical reaction with iodine. SOLUTION: A joint part 3 of inspected object 4 is covered with a sealed vessel 5 and a fluid element 2 containing an adsorbent 1 is connected. The fluid element 2 is made of transparent material or window is provided so as to see the contained adsorbent 1. In the case a defect occurs in the joint 3 of the inspected object 4 and leakage occurs, leaked gas flows to the fluid element 2 as the joint 3 is sealed in the sealed vessel 5 and the iodine contained in the gas is adsorbed in the adsorbent 1. Owing to the chemical reaction to iodine, the color of adsorbent 1 changes and leakage is detected by the color reaction. In the fluid element 2, gas having entered in the inlet fully passes in the fluid element 2 until going out of the outlet and adsorption performance of the adsorbent 1 is fully used.

Filed: 1991-12-06
Abstract: PURPOSE:To perform a planar setup that prevents any large irregularities from occurring by setting up plural pieces of filament electrodes parallelly, and forming them with a heating material being positive in a temperature factor of resistance value and an insulating material covering the electrode and the heating material. CONSTITUTION:Plural pieces of filament electrodes 1 parallelly set up at regular intervals with one another are formed with a heating material 2 being positive in a temperature factor interposed between these electrodes 1 and an insulating material 3 covering the electrodes 1 and the heating material 2. In addition, a sectional form orthogonal with the longitudinal direction is formed into an almost circular form. If so, in the case where it is bent and set up flatly, it is unnecessary to be twisted, namely, bendable only flection. With this constitution, work can be done so simply, and even if twisting is produced by flection, irregularities are in no case produced from the standpoint of appearance. In this connection, the electrode 1 is formed with a mid filament consisting of an insulating fiber and such one winding a metallic conductor spilally an this mid filament, and one side of the mid filament is colored, through which each of the electrodes 1 is made distinguishable.

Abstract: PURPOSE: To simplify constitution of the optical system of an optical pickup and to reduce cross talk noise by aligning the direction of an elliptic major axis of a spot converged to a land part and a groove part to the track direction. CONSTITUTION: Since a laser divergent light outgoing from a semiconductor laser is not isotropic in its light emitting shape, it forms a convergent spot 20 of an elliptic shape on the land part 21 or the groove part 22 through an optical system consisting of a collimate lens, a beam splitter, a 45 deg. mirror and an objective lens, etc. In the conditions that a track pitch is 1.4μm, both of widths of the land part 21 and the groove part are 22 0.7μm, and a recording bit length is 0.55μm, the convergent spot 20 whose diameter A in the direction of a mirror axis is 1.1nm, is formed by using the laser light of a wavelength of 680nm through the objective lens of a numerical aperture of 0.55.  At this time, the ratio of the diameter B in the direction of the major axis to the diameter A in the direction of the minor axis of the convergent spot 20 is set within the range of 1.1<=A/B<=1.3. Thus, a prism, etc., converting an elliptic beam into an isotropic beam is eliminated.
