Title: Gas self-generating type floating device
Inventor: SAKAMOTO YOSHIFUMI
IPC: B63C7/26
Filed: 1982-04-02
Abstract: PURPOSE:To obtain a gas under a high pressure through utilizing a hydrogen- generating reaction, by incorporating a substance which generates hydrogen when being brought into contact with water. CONSTITUTION:A balloon is fitted to metallic fittings incorporating an ampoule of sodium. When a lever fitted with a spring is pushed or knocked in starting a floating-up operation, the ampoule is broken to let sodium be exposed, and simultaneously, water is permitted to flow thereto. When the lever is released, it tends to return, thereby closing a water passage. Thereafter, water and sodium react with each other to form hydrogen, whereby the balloon is inflated. Accordingly, in cases of recovering a sunken ship, collecting submarine mineral ores or refloating materials, operations can be facilitated by fitting to or incorporating into a ship's hull a large-type or a plurality of balloons fitted with the gas generator.

Title: Purification of normal paraffin
Inventor: HIROOKA SEIJI
IPC: C07C7/12
Filed: 1981-04-10
Abstract: PURPOSE: To obtain normal paraffins in high purity effectively, by treating previously crude normal paraffin with china clay, carrying out common purification through removal of aromatic compounds, so that precursors which may be converted into aromatic hydrocarbons during chlorination and aromatic hydrocarbons are removed.  
     CONSTITUTION: Normal paraffins e.g., (crude normal paraffins obtained from mineral oil fraction by urea adduct process or molecular sieve process) are treated with china clay at 50W200°C, preferably at 100W150°C, aromatic hydrocarbons contained in the china clay treated oil are removed by common purification through removal of aromatic compounds, to give purified normal paraffins. Among the purifications through removal of aromatic compounds, purification through hydrogenation in the presence of a catalyst for hydrogenation is not preferable. Since the treatment with china clay is carried out at low temperature and only precursors for aromatic hydrocarbons are treated effectively, this process is extremely simple and can be done industrially.  
     USE: Especially a raw material for preparing chlorinated paraffins.

Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To discriminate bending of steel conveyed by roller from winding and prevent erroneous detection and accurately detect, by correcting the position shift due to moving, and measuring the displacement in shorter-side direction detecting the bending of long steel. SOLUTION: Distance sensors 41-1 to 41-3 and position detection sensors 42-1 to 42-n are arranged in parallel to the convey direction of the steel 2 with an equal interval (d). A control part 43 controls altogether. A data process part 44 inputs distance measurement information from distance sensors 41-1 to 41-3 as data and outputs steel bend detection data. A memory part 45 stores detected data outputted from the data process part 44. By this, bend is detected on the basis of actual moving distance and displacement of the steel, and so accurate detection is always possible. Since it is constituted to correct the position shift due to moving, erroneous detection is prevented.

Filed: 1982-03-31
Abstract: PURPOSE:To perform a stable operation even for a low voltage, by connecting the base of a controlling transistor TR to the base of an NPN TR of a holding circuit through a resistance. CONSTITUTION:When an input terminal 1 is grounded, the base current is flowed to a PNP TRQ1, and the collector current is flowed also, and the base current is flowed to an NPN TRQ2 to drive the NPN TRQ2, and therefore, the collector current drives the base current of the PNP TRQ1, and the holding circuit is formed by both TRs Q1 and Q2. When the operation holding voltage of a power source VCC is 0.85V, the base voltage of the NPN TRQ2 drives the base of a controlling TRQ3, and the collector of the controlling TRQ3 is set to the ground potential to operate an output terminal 2. Consequently, the low-voltage operation is possible.
