Title: Production of highly pure 4,4'-dihydroxydiphenyl sulfone
Inventor: OGATA EIJI
IPC: C07C315/04
Filed: 1990-10-02
Abstract: PURPOSE:To prepare the subject compound with high purity in high yield by subjecting phenol and a sulfonating agent to a dehydrative reaction in mesitylene as a reaction medium in the presence of an aromatic polysulfonic acid while suspending the resultant DDS in the medium. CONSTITUTION:Phenol and a sulfonating agent (preferably concentrated sulfuric acid) are subjected to a dehydrative reaction in mesitylene as a reaction medium in the presence of a compound of the formula (X is halogen, 1-2C alkyl; n is 0-2; m is 2, 3) such as benzene-1,3-disulfonic acid, while the produced dihydrodiphenyl sulfone (DDS) is suspended in the medium, thereby providing the highly pure 4,4'-DDS while remarkably suppressing the side production of 2,4'-DDS and inhibiting the side production of tri products. The 4,4'-DDS is heated at a temperature above the isomerization temperature of the 2,4'-DDS into 4,4'-DDS in the DDS-suspended state and/or in a solid state wherein all the liquid components are removed, thus providing 4,4'-DDS having a still higher purity in a high yield.

Title: Cross finger type converter and surface acoustic wave filter
Inventor: PIEERU DEYUFUIRI
IPC: H03H9/145
Filed: 1989-10-12
Abstract: PURPOSE: To reduce the frequency band width of an interdigital transducer(IDT) by specifying an interval between the centers of a first finger and an adjacent second finger. CONSTITUTION: This device is provided with a first comb PE1 having a first electrode or finger D1 , and a second comb PE2 having a second electrode or finger which are alternately arrayed on a substrate. Then, an interval between the centers of the first finger D1 and the second finger D2 adjacent to this first finger is made equal to at least Rλ0 /2, and the R is set as an integer strictly larger than 1 for the maximum part of the finger. Therefore, the number of active fingers per unit length is decreased, and the optimal length of each IDT with which an image impedance is connected is increased. Thus, the frequency width of the transducer is made narrow.

Title: Current mirror circuit
Inventor: MORIZAKI SHIGEKI
IPC: H03F3/343
Filed: 1984-12-19
Abstract: PURPOSE:To realize the mirror ratio with high accuracy even when the ratio of the mirro rate is large by connecting an input terminal of a current mirror circuit having a mirror ratio of 1: n to a collector of a transistor (TR) for IB compensation and using an output of said current mirror circuit as IB compen sation current. CONSTITUTION:When the mirror ratio of the current mirror circuit 15 is 1:n, the relation of nR3=R4 is established between a resistance value R3 of a resistor 11 and a resistance value R4 of a resistor 14. Thus, an input current IIN inputted to an input terminal 1 and an output current IOUT outputted from an output terminal 2 are expresed in equations (6) and (7). Thus, the mirror ratio CMR is expressed as CMR=IOUT/IIN. Since the error in the mirror ratio CMR is larger in proportion to the (n), the error is improved.

Title: Two-step chemical treatment of waste water containing reductive sulfur compound
Inventor: KANEMORI NOBUYUKI
IPC: C02F1/76
Filed: 1993-10-25
Abstract: PURPOSE:To provide sufficiently satisfactory quality of treated water by injecting sodium hypochlorite as to make oxidation-reduction potential be with in a specified range in a reaction tank for a first stage and as to make the remaining chlorine concentration be a specified level in a reaction tank for a second stage in the case waste water containing reductive sulfur compounds is chemically treated. CONSTITUTION:Waste water containing reductive sulfur compounds is led at first to a primary oxidation tank 1, ORP (oxidation-reduction potential) is measured by an ORP meter 3 in a pH range as high as pH10-13, and the injection amount of sodium hypochlorite is so controlled as to make the ORP be in a range from -100mV to +100mV. Then, the waste water is transported to a secondary oxidation tank 2, remaining chlorine concentration is measured by a remaining chlorine concentration measuring meter 4, and the injection amount of sodium hypochlorite is so controlled as to make the remaining chlorine concentration be 20mg/l or less. Since the treated water which comes out of the secondary oxidation tank 2 contains 20 mg/l of the remaining chlorine or less, after the remaining chlorine is reduced by a reducing agent, e.g. sodium hydrogensulfite, in a reducing tank 5, the resulting water is discharged. As a result, the remaining chlorine concentration is suppressed to low level and the injection installation of the reducting agent can be made small.

Filed: 1989-10-14
Abstract: PURPOSE:To obtain a low cost and highly reliable inverter apparatus for driving an induction motor by providing DC circuits with overvoltage detecting circuits, inverter protecting circuits and a return path for connecting both negative sides of the DC circuits. CONSTITUTION:Inverters 7 and 17 drive an induction motor 9 via output transformers 8 and 18, respectively.

SOLUTION: A solid phase ratio in the center of a cast billet at the inlet side of a light rolling reduction zone is made to <=0.3 and the solid phase ratio in the center of the cast billet at the outlet side of the light rolling reduction zone is made to >=0.7. It is preferable to make the solid phase ratio in the center of the cast billet at the inlet side of the light rolling reduction zone to <=0.4, the solid phase ratio in the center of the cast billet at the outlet side of the light rolling reduction zone to >=0.6 and a standard deviation of variation in a casting speed to <=0.05 m/min. The cast billet having good quality can be produced while keeping the high productivity.  A merit of energy reduction is obtd. because a blooming process can be omitted and the energy needed to the production is reduced in comparison with the production of the billet with the blooming process after producing the billet in the bloom.
