Title: Counter circuit
Inventor: YANAKA HIROYUKI
IPC: G06F7/04
Filed: 1985-12-27
Abstract: PURPOSE:To decrease the number of test patterns and to shorten the test time when a counter circuit is tested by using plural binary up-counters with set/reset functions, comparison registers, AND gates, comparators, etc. CONSTITUTION:The values of AND gates 20-23 are decided by the set signal S and set data signals B1-B3. Then the values of binary up-counters C20-C23 are decided by the values of gates 20-23 respectively. When a counter circuit is tested, the coincidence is checked between the counters C20-C23 and registers R20-R23. In this case, '1111' is set to registers R20-R23 and '1110' is set to counters C20-C23 by the signals B1-B3 and the signal S. Thus the coincidence is secured between those counters and registers just with a single count-up action of the counters C20-C23 done by an input pulse I. That is, the count-up frequency can be decreased by setting optionally the initial values of counters C20-C23. This decreases the number of test patterns and also reduces the test time.

Filed: 1997-10-14
Abstract: PROBLEM TO BE SOLVED: To facilitate execution and to surely protect a growth foundation bed material and plants by forming a nearly box-like shape opened upward with an elastic material such as a net material or a bamboo material, and curving at least its front face to form a wave-dissipating flow velocity-resistant face. SOLUTION: The whole is formed with an elastic material such as a net material or a bamboo material, the front face is curved to form a wave-dissipating flow velocity-resistant face 11, and a wave-dissipating flow velocity-resistant vegetation wicker 10 is constituted. Irregularities 11a are formed on the wave-dissipating flow velocity-resistant face 11. Waves complexly collide with wave-dissipating flow velocity- resistant vegetarian wicker 10 and are reflected and suppressed by meshes, thus no wave force infiltrates into the wave-dissipating flow velocity-resistant vegetation wicker 10 as a result.  Since no wave force infiltrates into the wave-dissipating flow velocity-resistant vegetation wicker 10, the growth points of plants can be directly protected, and the roots of the plants are prevented from being completely drifted off or damaged by waves or streams during the growth process of plants.

Title: Method for cold rolling of titanium stock
Inventor: KUWAMOTO HIROSHI
IPC: B21B3/00
Filed: 1987-11-26
Abstract: PURPOSE:To display good lubricity and to improve the productivity by forming a copper film on a titanium stock by performing copper plating and then cold rolling the stock under existence of a lubricant. CONSTITUTION:Direct contact of titanium with steel and generation of build-ups are prevented because a copper film exists on the titanium stock surface in a cold rolling stage. Further, copper reduces friction resistance in roll biting in cold rolling to facilitate plastic deformation of the titanium stock. The lubricant forms a liquid film between the copper film and a work roll to keep a low friction coefficient in the roll biting, so that increase of the friction coefficient is restricted by the action of copper even if the liquid film is broken; further, heat generated during cold rolling is removed by the action of the lubricant.

Filed: 1987-11-26
Abstract: PURPOSE:To enable the easy manufacture of a gas sensor element detecting nitrogen dioxide, a toxic gas, with high sensitivity, by using a material of a specific structural formula and by adopting a unimolecular accumulation method suitable for making the material into a thin film. CONSTITUTION:A material of a structural formula shown in the formula is used. The molecule of this material is a polyamide acid containing copper phthalocyanine. Such a molecular structure as shown in the formula is adopted for making the material soluble in a unimolecular accumulation method. Consequently, a copper (II) phthalocyanine polyamic acid is used. When this molecule is dissolved in an organic solvent and developed on a water surface, the lower side of a prescribed molecular formula is positioned on the water surface side, since a carboxyl group is a hydrophilic group. Subsequently, a pressure is applied on a film developed on the water surface to put it in the solid state. Then, the film is transferred onto a glass substrate 204, about ten layers of unimolecular films 203 are accumulated by the unimolecular accumulation method, and metal electrodes 201 and 202 are attached thereon. Next, the concentration of gas is detected from a change in conductivity between the electrodes due to the adsorption of the gas to be inspected to the surface of this thin film.

Title: Safety device for hot water supplying apparatus
Inventor: ADACHI IKUO
IPC: F24H1/10
Filed: 1990-11-02
Abstract: PURPOSE:To improve safety by preparing composition of a light transmitting line made of synthetic resin so as to largely reduce its light transmission factor at a set temperature or to shut OFF a light transmission, and inserting the line to an optical signal circuit. CONSTITUTION:If a hot water supplying apparatus is used for a long period and the body of a heat exchanger 1 is thermally deteriorated to be partly damaged, hot air is leaked from the damaged part so that the temperature of the vicinity of a light transmission line F is raised to become its set temperature. Since the line F is made of composition for largely reducing its light transmission factor at the set temperature or shutting OFF the light transmission, the light transmission factor of the line F is largely reduced or shut OFF at this time to vary the output of an optical signal circuit 4. Thus, the driver of a safety device is operated, and the operation of a burning unit is stopped. That is, combustion is stopped. Thus, the safety is improved.
