Title: Heat-exchanger with fouling preventing
Inventor: TANAKA KENJI
IPC: F28F27/00
Filed: 1995-02-08
Abstract: PURPOSE: To suppress probiferation of fungus and to prevent adhesion of slime to a heat transfer pipe by maintaining the temperature of the heat transfer pipe at a high temperature exceeding a specified temperature. CONSTITUTION: Cooling water is caused to flow from a cooling tower 1 to a heat-exchanger 3 through a cooling water pump 2 and circulated to the cooling tower 1 to form a cooling water circulation system. A boiler 14 is provided to feed hot water to the cooling water circulation system and by utilizing the operation stop period of the heat-exchanger 3 during midnight, a part of hot water heated by a boiler 14 is caused to flow to the cooling water circulation system and the temperature of the heat transfer pipe of the heat-exchanger 3. This constitution maintains temperature in the heat transfer pipe of the heat-exchanger 3 at temperature exceeding a specified temperature for a specified time, resulting in extinction of microoganisms or suppression of breeding thereof and prevention of adhesion of slime to the heat transfer pipe.  Thus, heat transfer characteristics are prevented form deterioration.

Title: Preparation of tertiary olefin
Inventor: ARAKI MASASHI
IPC: C07C11/02
Filed: 1981-02-13
Abstract: PURPOSE: To inhibit the accumulation of carbon on the catalytic surface and prevent the deterioration of the catalytic activity, by using a carrier having a small surface area obtained by calcining at a high temperature as a carrier for a metallic sulfate catalyst in decomposing an alkyl tertiary alkyl ether into a tertiary olefin.  
     CONSTITUTION: An alkyl tertiary alkyl ether, e.g. methyl tertiary butyl ether, is decomposed to give a tertiary olefin. In the process, a carrier obtained by  calcining at a high temperature, e.g. 500W2,500°C, and having a specific surface  area ≤20m 2 /g, e.g. alumina, silica, or silicon carbide, is used as a carrier for  supporting a metallic sulfate catalyst. The prolonged catalytic life lengthens the  regeneration or changing interval of the catalyst, and this method has a very  great industrial significance.

Title: Stabilizing method for interval of oscillation frequency of laser device
Inventor: SHIMOZAKA NAOKI
IPC: H01S3/13
Filed: 1988-01-29
Abstract: PURPOSE:To enable a control action to be held stable even under the presence of disturbance, by a method wherein the range of frequency of a frequency sweeping light is controlled so that the difference between the sweep starting time of the frequency sweeping light and the generating time of a pulse firstly generated in the reference pulse train which is generated within one time coefficient substantially coincides with a predetermined reference value. CONSTITUTION:A T flip-flop (T.FF) is driven by the first pulse out of the reference pulses which are inputted to the section indicated by a dotted line, and corresponds to both the pulse generated at the starting point of a sweep period and the output pulse of an optical resonator. Then, the output of the T.FF becomes a square wave having a starting point and an ending point which are set by the continuous two pulses. Since the height of the square wave is equal to a logical level EL and constant at all times, the square wave is integrated with an integrator in the next stage, and thereby an output ELDELTAt at corresponding to a time difference DELTAt between the continuous two pulses is obtained. When the time difference DELTAt between the two pulses is in the range of 0<=DELTAt<=t1, t2<=DELTAt, a control loop is closed, and an error signal is fed back to a DBR1. This prevents the first pulse from dissipating and another pulse preceding to the original first pulse from generating. Accordingly, a stable system can be formed in which the control does not fail even under the presence of disturbance.

Title: Speaker system
Inventor: SATO KAZUHIDE
IPC: H04R1/00
Filed: 1989-01-31
Abstract: PURPOSE:To eliminate the standing waves produced between a speaker cabinet and a wall surface and to obtain the flat frequency characteristics by preparing a module having an acoustic port containing a sound absorbing material at the periphery of the cabinet when the cabinet having an acoustic port on its back is attached to the wall surface. CONSTITUTION:The sound waves produced on the back of a diaphragm 1 are radiated to outside via the inner capacity 4 of a cabinet 3 and then an acoustic port 5. In a speaker system an acoustic space 7 is secured between the back of the cabinet 3 the wall surface so as not to close the port 5 and the cabinet 3 is fixed to the wall surface. A standing wave is produced in the space 7 with a specific frequency decided by the form of the space 7. This standing wave gives the adverse influence to the reproduced sound pressure frequency characteristics of the speaker system to produce the sound pressure characteristics having many deep dips. Thus an acoustic port module 8 containing an acoustic port 9 is prepared around the cabinet 3 in order to suppress the standing wave. That is, the port 9 having an extremely high input/ output frequency of sound waves contains a sound absorbing material 10 to effectively eliminate the standing wave.
