Title: Concrete lid catch
Inventor: OGAKI MAMORU
IPC: E03F5/04
Filed: 1995-04-20
Abstract: PURPOSE: To easily position a catch point and stably transmit a chain force for lifting to catch shafts, by arranging the L-shaped catch shafts in the both sides and providing respective fulcrums in the insides of the opposed points. CONSTITUTION: A concrete lid catch is provided with L-shaped catch shafts 1 in its both sides so that fulcrums 2 in the case of lifting a load by lift chains 5 are arranged to fall on the inside of points opposed to the catch shafts 1. As a result, a lift is stably transmitted to the catch shafts 1 via the chains 5 so that the angle affecting no disturbance on the work can be secured by distribution of the lever force, even if the surface of a load is covered with high humidity muddy soil. A leaf spring for a light vehicle is used as a material for the catch shafts 1 and it is desirable that a steel plate line in the side of the chains 5 is soft iron.

Title: Buffer control system
Inventor: SUGAYA SEIICHI
IPC: G06F11/14
Filed: 1980-09-24
Abstract: PURPOSE:To simplify the control of a buffer with reduction of the number of component parts and at the same time to realize an efective error recovering process for the control system of a data correcting buffer, by using in common both an error correcting buffer and a transfer buffer which are necessary for the error recovering process. CONSTITUTION:A record is formed with plural data blocks on a recording medium, and the error caused in each data block is corrected and retransferred by a data transfer controller. In such controller, a transfer buffer and an error correcting buffer are used in common. Then a commonly used buffer 100 is divided, and the error correcting or reusable data block uses the 1st region 100a of the buffer 100. And the subsequent data block uses the 2nd region 100b to execute the transfer. The data within the region 100a is preserved, and this preserved data is corrected and transferred again when an error occurs.

Filed: 1989-05-29
Abstract: PURPOSE:To increase the angle of deflection by combining a means which supplies an external signal for controlling an effective refractive index to an optical waveguide with a coupler which guides waveguide light out at an angle corresponding to the effective refractive index. CONSTITUTION:The optical deflector consists of the optical waveguide 2 which has an input part 3 for light propagated in the waveguide at one side and an output part 5 on the other side, the means 4 which supplies the external signal for controlling the effective refractive index, and the output part 5 composed of the grating coupler 5 which guides the waveguide out at the angle corresponding to the effective refractive index.

Filed: 1995-05-31
Abstract: PURPOSE: To obtain the slot assignment method in a satellite communication system in which number of slots assigned to a peripheral station making transmission by the PA system is increased tentatively and the transmission system is changed in the unit of data. CONSTITUTION: A transmitter-receiver 1 of a center station applies time division to a slot via an artificial satellite from plural peripheral stations and shares channels in common and receives a signal sent by a permanent allocation(PA) system.

The multiplexer section 8 applies time division multiplexing to slot information and transmission data.  The center station of this configuration manages all PA slot information and delivers the result of management for each frame to the peripheral station through broadcasting and adds slot assignment processing to the PA system on reservation request.

Title: Method of refining propylene oxide by extractive distillation
Inventor: UIRIAMU ARAN SUMISU
IPC: C07D303/04
Filed: 1995-05-31
Abstract: PURPOSE: To purify propylene oxide by removing oxidized impurities such as water, acetone, methanol or the like from crude propylene oxide of lower purity by extractive distillation.  
     CONSTITUTION: The method of this invention is to feed crude propylene oxide of low purity into the lower half part of an extractive distillation column and to feed extractive distillation agents containing propylene oxide adducts of oxyethylene glycols, or ethylene glycols into the upper part of the extractive distillation column. The ratio of the crude raw materials to the extractive distillation agents is (1:1) to (20:1). The fed ethylene glycols are converted into propylene oxide adducts of ethylene glycols during distillation and contribute as an extractive distillation agent. Extractive distillation of propylene oxide is attained by extracting low-boiling fraction from propylene oxide contaminated with reduced quantities of water, acetone and methanol and by extracting formed propylene oxide adducts of oxyethylene glycols and high-boiling fraction containing migrated water, acetone and methanol.

Abstract: PURPOSE: To improve safety of a rice-cooker to troubles of an electricity feeding controlling means by providing in multiplicity the electricity feeding controlling means for shutting energizing of electricity to a heating means by using a pot switch, a pot temp. sensor and a temp. fuse. CONSTITUTION: When a pot 4 is not stored in an inner frame 2, a pot switch 26 outputs a signal of absence of a pot to stop feeding of a high frequency electric current and to stop heating. When rice cooking and temp. keeping are performed and the detecting temp. of a pot temp. sensor 23 or a lid temp. sensor 52 reaches at least 120 deg.C being a first specified temp., feeding of the high frequency electric current is stopped and heating of the pot 4 is checked. In addition, in the case when a microcomputor and temp. sensors 23, 52 become out of order, energizing of electricity is kept as it is. However, even in the worst case, when the temp. reaches at least 129 deg.C being a second specified temp., temp. fuses 21 and 22 are worked and a circuit for feeding an electric source to an induction heating means and heaters 20 and 51 is shut down.  Therefore, there exists no possibility of returning of this circuit again and heating of the pot 4 is completely checked.
