Title: Production of dimethyl ether
Inventor: ONO MASAMI
IPC: C07C41/01
Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To provide a process that can continue the production of dimethyl ether in high yield from a starting gas mainly comprising carbon monoxide and hydrogen, as the conversion of CO is kept high. SOLUTION: A starting gas at least containing carbon monoxide and hydrogen is catalytically reacted with other to produce dimethyl ether and the carbon monoxide and hydrogen remaining in the reaction mixture are reused by circulation. The carbon dioxide accompanied by carbon monoxide and hydrogen to be circulated is brought into contact with the liquid dimethyl ether separated from the reaction mixture whereby the carbon dioxide is absorbed in the dimethyl ether and removed.

Title: Gas pressure support device of exhaust gas boiler
Inventor: MAEHARA SEIJI
IPC: F23M5/04
Filed: 1994-06-07
Abstract: PURPOSE:To prevent the generation of a large load due to heat transfer difference of their connected parts and protect against damage by installing a reinforcing steel material which supports a gas pressure of an exhaust gas boiler and a tension rod in the gas substantially under the same condition. CONSTITUTION:A reinforcing steel plate 3 is L or C-shaped in cross section and designed to increase its strength so as to prevent the deformation of a casing 1 induced by the pressure of gas and supported from the internal gas pressure while it is arranged to restrict the gas flowing between the sides of heat exchanger tube groups 2 and the internal surface of the casing 1 where the short pass of gas is likely to occur. In addition, the reinforcing steel material 3 laid out as opposed is connected with a tension rod 4 at a specified spacing. It is, therefore, possible to prevent the generation of load due to a heat transfer difference on a jointed area where the end of the tension rod 4 is connected to the reinforcing steel material 3 and protect the jointed area from being damaged even when the temperature of gas rises dramatically.

Title: Semiconductor-laser driving apparatus
Inventor: HAKAMATA ATSUSHI
IPC: B41J2/44
Filed: 1993-04-28
Abstract: PURPOSE:To maintain excellent picture quality even if the characteristics of elements affecting on the picture quality are changed in a semiconductor-laser driving apparatus, which modulates laser light in response to picture signals in many gradations. CONSTITUTION:In a semiconductor-laser driving apparatus, which controls a laser driving signal in response to picture signals in many gradations, a detected disturbance signal and the picture signal are synthesized in a DA converter 45 so that the picture signal is located at the upper-bit side and the detected disturbance signal is located at the lower-bit side. The detected disturbance signal is the signal, which is obtained by detecting the error from the expected state of an element affecting on picture quality (e.g. the surface potential of the drum of a photosensitive body and the density of a toner). The laser driving current of a semiconductor laser diode 3 is controlled by the synthesized signal. Then, the detected disturbance signal finely adjusts the intensity of the laser light when the laser light is modulated by the picture signal, and the error of the element affecting the picture quality is compensated. Therefore, the excellent picture quality can be maintained.

Title: Connector
Inventor: NISHIDE SATORU
IPC: H01R13/64
Filed: 1997-05-15
Abstract: PROBLEM TO BE SOLVED: To surely detect incompletely fitted state and shorten the fitting stroke at the time of fitting by inertia regarding connectors to be normally fitted at once by utilizing inertia. SOLUTION: Since the fitting operation by inertia is carried out in a state that fitting proceeds to a some extent and a movable member 14 is at a recessed position, the fitting stroke by inertia is short as compared with that in the case fitting operation is carried out immediatdly after the starting of the fitting. In the half-fitted state, the movable member 14 is turned back to an advanced position by a contracted coil spring 18 and following that, since both connector housings are displaced in the directions in which both are parted, half-fitted state can consequently be detected.

Title: Structure of brake drum
Inventor: AKAISHI TAKAYUKI
IPC: F16D65/00
Filed: 1979-09-29
Abstract: PURPOSE: To prevent the brake squeal that is possibly caused by the frictional vibration and the resonance of a brake drum, by forming at least three thick sections equidistantly along the outer circumference of a cylindrical part of the brake drum.  
     CONSTITUTION: Three thick sections 10 projected radially outwards of the cylindrical part 1a of the brake drum 1 are formed equidistantly along the outer circumference of the cylindrical part 1a, in the manner that the circumferential length l 1  of the thick rection 10 is substantially equal to that l 2  of thin rection 11. With such an arrangement, when radially outward elastic deformation of the brake drum 1 is caused by the contact of brake shoes 2, it takes the form of a tertiary vibration with its nodes being located at thick rections 10 and loops being located at thin sections 11, since the magnitude of elastic deformation at the thick sections 10 is different from that at thin rections 11. Since the matural frequency of the brake drum 1 is shifted to a higher region, the noise level of brake rqueal caused by the resonance with the natural vibration of the brake drum can be lowered.

Abstract: PURPOSE:To detect a fault of a connecting line to a telephone set and a fault of a fault detector itself with simple constitution by discriminating normality of an automatic exchange based on time data from the pseudo call till the detection of a confirming tone. CONSTITUTION:When the automatic exchange 1 is faulty, a control circuit 52 makes a pseudo call and no ring back tone B is obtained via a voice circuit 2. The control circuit 52 uses time data and compares with a maximum/minimum normal time data and since no ring back tone B comes and no detection result signal C is obtained, the circuit outputs a control signal D at a prescribed time after the pseudo call. Thus, an oscillation circuit 55 outputs an oscillation signal E to a speaker 28. An alarm tone is raised from the speaker 28.
