Title: Ozone generator
Inventor: TAKEWA TAICHI
IPC: C01B13/11
Filed: 1977-11-09
Abstract: PURPOSE: To improve performance of ozone generator, it is provided with wick which contacts with inner periphery surface of a dielectric tube and a cooling tube is inserted inside of the dielectric tube, along the axis of the tube so that operating fluid causes to flow toward inner diameter of the dielectric tube.  
     CONSTITUTION: Wick 16 contacts with an inner surface of an dielectric tube 15 in an ozone tube 12. Therefore, the wick 16 is wholly wet with vaporizing liquid such as water. Silent discharge occurs at an outer surface of the ozone tube 12 and generates heat. The generated heat causes pure water to vaporize from the inner wall surface of the dielectric tube 15. The water vaporization effects cooling of the inner wall. Water vapor condenses on the surface of a cooling tube 18, then waterdrops form and grow to a certain size and fall down as indicated by arrow 22. The fallen waterdeops reach the bottom of the wick 16, then permeate the whole space through strong capillary action of the wick 16. This maintains the wick 16 at a constant wetness. This function as described, i.e., heat pipe action, contributes to an effective and safe internal cooling operation of the ozone tube 12.

Title: Semiconductor circuit
Inventor: YAMAZAKI SU
IPC: G11C11/41
Filed: 1999-05-14
Abstract: PROBLEM TO BE SOLVED: To shorten an operation cycle time by shortening a precharge period without increasing a judgment period in a semiconductor circuit in which a potential drop because of coupling noises is brought about to the other signal line when one signal line of an SP/SN is discharged by a discharge circuit at a judgment time. SOLUTION: With a sum of W1 to W3 being kept constant, kg is determined in a range of an expression whereby a recovery time of an SP/SN can be regarded as shortest to kc. The expression is 0.49.kc+0.08<=kg<=0.47.kc+0.31. Since a load of a circuit for driving a CK is constant, a precharge period can be shortened without increasing a judgment period. For example, when kc=0.05 is held, kg becomes 0.105<=kg<=0.334, whereby the recovery time can be shortened by 13 to 14%, and the precharge period and an operation cycle time can be shortened accordingly.

IPC: C07C69/82
Filed: 1998-04-08
Abstract: PROBLEM TO BE SOLVED: To recycle a waste PET and thereby obtain a material which can be used as a lubricating oil or a plasticizer having excellent properties by reacting polyethylene terephthalate with tridecyl alcohol. SOLUTION: Waste PET bottles, other recycled PET products, off-spec products in PET production processes, or the like can be used as the waste PET (polyethylene terephthalate). In the reaction, tridecyl alcohol is added usually in an amt. of 2.5-8 mol per mol of terephthalic acid unit in PET. A catalyst may be dispensed with, though the reaction is accelerated by the use of antimony trioxide, or the like. The reaction temp. is about 200-260 deg.C. Ethylene glycol produced as a by-product is removed from the reactor under normal or a reduced pressure. If the resulting ester oil has a polyester content of about 10% or lower, the ester oil can be satisfactorily used as a lubricating oil or a plasticizer.

Title: Battery switching type subscriber loop interface circuit
Inventor: LUDEMAN CHRISTOPHER
IPC: H04Q3/42
Filed: 1999-05-14
Abstract: PROBLEM TO BE SOLVED: To make it possible to efficiently and automatically supply a subscriber loop with a power by supplying a subscriber loop interface (I/F) circuit with a power by a main power source, supplying the I/F circuit with the power by a secondary power source smaller than the main power source as a required element of a desired power of the detected I/F circuit and reducing a power consumption. SOLUTION: Regarding an SLIC: 100, when a loop resistance lowers, an output voltage of a RING line amplifier 14 is raised over a main power VBAT1 voltage -48 V. With respect to the line amplifier 14, when the output voltage exceeds a secondary power source VBAT2 voltage 24 V+Vd (voltage lowering of a diode 22), an output current flows the diode 22, and is led to the secondary power source VBAT2. Therefore, the current is a correlational element of the diode 22 and is in a scale of the secondary power source VBAT2. Thus, it becomes possible to automatically reduce a power consumption of the SLIC: 100 which is supplied with a subscriber's loop by the secondary power source smaller than the main power source.

Filed: 1991-06-06
Abstract: PURPOSE:To provide the IC card having a key signal which is safe in case of wiretapping by increasing the security of key data used by a satellite broadcast receiver, etc., to reset a scramble signal. CONSTITUTION:A 1st key 19 is ciphered with a 2nd key 21 into ciphered key data 20. Then the key data 20 are deciphered by deciphering algorithm 23 and recorded as a 3rd key 24 in a RAM 15 as a 2nd memory means. The RAM 15 as the 2nd memory means is a volatile memory, so when the IC card 11 is extracted from a card reader for the analysis of the key data, the 3rd key 24 recorded in the RAM 15 as the 2nd memory means is erased and the analysis is impossible. This IC card is therefore high in the security of the 3rd key 24 and safe against wiretapping.
