Title: Preparation of monocarboxylic ester
Inventor: ISHIKAWA KATSUHIRO
IPC: C07C69/753
Filed: 1981-10-29
Abstract: PURPOSE:To obtain titled compound in high yield with suppressed side reactions, by reacting a cyclopentadiene having a norbornene ring with CO and an alcohol in the presence of a cobalt compound catalyst while controlling the amount of a pyridine base, temperature and pressure. CONSTITUTION:A cyclopentadiene having a norbornene ring is reacted with CO and an alcohol in the presence of a cobalt compound, e.g. cobalt carbonyl, as a catalyst. In the process, the reaction is carried out in the presence of a pyridine base, preferably pyridine or beta- or gamma-picoline, in an amount of 0.5mol or more, preferably 0.8-2.0mol, based on one mole cyclopentadiene, at >=20kg/ cm<2>.G CO pressure and 80-140 deg.C, preferably 100-130 deg.C. Thus, side reactions unique to the double bond in the norbornene ring and thermal decomposition, polymerization, etc. of the cyclopentadiene are suppressed to give the aimed monocarboxylic ester.

Title: Warning system
Inventor: KIDO SUSUMU
IPC: G08B25/00
Filed: 1987-07-10
Abstract: PURPOSE:To prevent the malfunction of a host equipment by preventing an origination to the host equipment even if the power source of an equipment which originates a warning only at the time of failure and the power source of an equipment which originates a warning at both cases of failure and power source turning off are turned off simultaneously when said two kinds of equipments exist together with each other. CONSTITUTION:The B equipment 2 has a b-contact al2 that closes at both cases of failure and power source turning off. The A equipment 1 has an a- contact al1 that closes at the case of failure and an a-contact rl that closes in delay only at the time of power source turning on by an opening/closing circuit 11 consisting of a transistor, a capacitor, and a resistor, etc. The contacting point al1 is connected in parallel with a serial circuit of the contacts al2 and the rl, and when either circuit is conductive, the warning is originated to the heat C-equipment 3. By such a constitution, even if the power sources of the equipments 1, 2 turn on/off, the serial circuit of contacts al2 and rl do not close, hence the warning signal is not originated to the equipment 3. As a result, the equipment 3 can be prevented from malfunctioning.

At first, tetraethoxysilane is irradiated from a gas cell 4 to the silicon substrate at the substrate temperature of 200 deg.C. Tetraethoxysilane gas is supplied from a gas bomb 5 to the gas cell. After the supply of tetraethoxysilane, the gas is once exhausted in the deposition device. Then, the substrate temperature is made to increase to 400 deg.C, and the silicon oxide film is deposited up to 1000Angstrom  on the surface of the substrate by Chemical Vapor Deposition method after inducting silane gas 8 and oxygen 9 from gas cells 10 and 11 into the deposition device, respectively.

Title: Packaging mortar for roof tile substrate
Inventor: AIGAMI AKIMITSU
IPC: C04B28/12
Filed: 1995-07-07
Abstract: PROBLEM TO BE SOLVED: To make it possible to take out the required amt. at the time of use, to make the balance usable in later days, to increase the viscosity of mortar and to enhance the strength by compounding lime, calcium carbonate, a lightweight aggregate, cement, a curing retarding agent and water at prescribed ratios and bagging the mixture. SOLUTION: The lime is added at 1 to 6 pts.wt., the calcium carbonate at 1 to 15 pts.wt., the lightweight aggregate at 3 to 5 pts.wt., the cement at 0.1 to 0.5 pts.wt., the curing retarding agent (e.g.: molasses) at 0.1 to 0.3 pts.wt. and the proper volume of the water and the mixture is kneaded and is bagged. Since the packaging mortar using the lightweight aggregate is formed, a user is merely required to open the bag, to take out the required amt. and to hermetically seal the bag. The lightweight mortar having a good preservable property is thus obtd. and in addition, the on-site kneading work is entirely eliminated. Pearlite or foamed styrol grains (1 to 2mm) are used as the lightweight aggregate. Bags made of synthetic resin films having no air permeability are used for packaging. The mortar is usable for lath boards or joint mortar and other general buildings as well.

Abstract: PURPOSE:To prevent a reading window from being broken or a commodity from being flawed by setting the upper surface of a commodity data reading means including the reading window lower than the upper surface of a case body along the moving direction of the commodity at the time of reading commodity data. CONSTITUTION:A step part 11b is formed along the moving direction of the commodity at the time of reading work on the upper surface 11a side of the case body 11, and the reading window 12a of the commodity data reading means 12 is installed at the nearly central part of this step part 11b. In this case, since the upper surface of the commodity data reading means 12 including the reading window 12a is lower than the upper surface of the case body along the moving direction of the commodity at the time of reading the commodity data, the space of the lower part of the commodity at the time of the reading work is expanded. Thus, since the commodity becomes difficult to collide with the upper surface 12b of the commodity data reading means 12, an accident that the reading window 12a is broken or the commodity is flawed is reduced.

IPC: F04D15/00
Filed: 1985-08-08
Abstract: PURPOSE:To enable reduction of the size of a thrust bearing and incurring of a bearing loss, by a method wherein, through introduction of a part of seal liquid, used in a shaft sealing device, to a pressure chamber, shaft thrust coping with shaft thrust generated by working gas is generated to balance the two thrusts with each other. CONSTITUTION:An oil film seal 25 serving as a shaft sealing device near an impeller 22 is placed, and seal liquid having a pressure Po+DELTAP is fed. When a part of seal liquid is guided in a pressure chamber 29, provided the area, on which a seal liquid pressure is exerted, of a balance disc 27 secured on a rotary shaft 21 is A1, rightward shaft thrust, produced by a disc 27, is A1(Po+DELTAP). Meanwhile, since leftward shaft thrust produced by working gas is A0Po A1(Po+DELTAP). A thrust load exerted on a thrust shaft 24 can be reduced about to zero. This enables reduction of the size of a thrust bearing and decrease of incurring of a bearing loss.
