Title: Catalyst for purification of exhaust gas
Inventor: SUZUKI HIROMASA
IPC: B01J29/89
Filed: 1990-11-27
Abstract: PURPOSE:To simultaneously remove hydrocarbon, CO and NOx in exhaust gas by using a catalyst obtd. by supporting Pt and Cu and/or Co on crystalline titanosilicate having a specified compsn. CONSTITUTION:Pt and Cu and/or Co are supported on a crystalline compd. having a silicate skeleton with incorporated Ti ions and represented by formula I (where M is an Na or K ion and(n)< 27) to form a catalyst. In order to support the Pt and Cu and/or Co on the crystalline titanosilicate represented by the formula I, ion exchange may be carried out as usual by stirring an aq. soln. of metallic salts mixed with iron silicate. The titanosilicate can be synthesized by hydrothermally compounding water glass as a prescribed silicate with Ti ions, etc. The formed catalyst accelerates the reaction of hydrocarbon with NOx in exhaust gas in preference to the reaction of the hydrocarbon with oxygen.

Title: Object detecting apparatus by optical method
Inventor: TAGO MAKOTO
IPC: G01H9/00
Filed: 1990-11-26
Abstract: PURPOSE:To make it possible to detect an operating object simply and securely by polarizing and modulating the transmitted light into a frequency according to oscillation with the oscillations of a plurality of tuning forks which are arranged in the longitudinal direction of an optical fiber and have the different natural frequencies. CONSTITUTION:Light from a light source 1 such as an LD having the intense linear poralization property is transmitted through an optical fiber 2 all the time. When an object is operated and, e.g. a tuning fork 32 is struck, the light transmitted through the optical fiber 2 undergoes polarization modulation into the frequency corresponding to the oscillation which is caused by the strike. The natural frequencies of the tuning forks 31, 32... are different. The polarized and demodulated signals are taken out of the emitting end of the optical fiber 2 with an analyzer 5 and a filter 6. The frequency is compared with a preset frequency. Then, the operated object among many objects can be detected.

Title: Discharge lamp lighting device and information apparatus equipped with same
Inventor: OKADA TAKASHI
IPC: H05B41/24
Filed: 1998-11-12
Abstract: PROBLEM TO BE SOLVED: To enhance safety of a lighting device by stopping the supply of power to a discharge lamp when lighting instability of the discharge lamp or flickering thereof is detected. SOLUTION: If connector insertion is incomplete between a lighting circuit 3 and a discharge lamp 4, a current flowing through the discharge lamp 4 is reduced, an output voltage of a current detector 5 is reduced, variation in the current flowing through the discharge lamp 4 is increased, and the discharge lamp 4 begins flickering. In the flickering of the discharge lamp 4, if an off period is maintained for a certain time, a transistor 43 is turned on by a voltage charged in a capacitor 41 of an operation abnormality detector 7, a voltage inputted into the plus side of an error amplifier 26 in an operation signal generator 6 becomes zero, and the output of the operation signal generator 6 maintains an off state. Because no voltage is supplied to the lighting circuit 3, operation of the lighting circuit 3 is stopped, then the transistor 43 of the operation anomaly detector 7 maintains ON, and therefore operation stop of the lighting circuit 3 is maintained.

Title: Automatic commutation ticket issuing machine
Inventor: OGASAWARA KAZUO
IPC: G07B1/00
Filed: 1988-12-19
Abstract: PURPOSE:To integrate a new ticket issuing mechanism and an old ticket processing mechanism with each other and to simplify and miniaturize the machine by putting a new ticket between brake rollers, fixing the new ticket, and separating the new ticket from the driving force of a carrying belt conveyer when the new ticket is issued. CONSTITUTION:Under a state in which freely rotatable carrying rollers 20-22 are allowed to contact with a carrying belt conveyer 16, the new ticket is sent to a commutation ticket port 2 by the driving of the conveyer, and after that, the rollers 20-22 are moved down. Further, a lower side brake roller 28 is moved up, the new ticket is put between the roller 28 and an upper side brake roller 27, and a stopper 37 is projected in a carrying path 1. Thus, even when the conveyer 16 is inversely driven in a direction to take in the commutation ticket, the new ticket is never taken in again by braking force to work on the new ticket and blocking force by the stopper 37. Consequently, even when a user never pulls out the issued new ticket, the conveyer 16 is driven separately from the new ticket, and an oil ticket under a standby state is carried to the internal part of the machine.

Filed: 1988-12-21
Abstract: PURPOSE:To detect the presence of a ribbon and the slip-off of the ribbon by one sensor by installing a reflection type photosensor near the nose of the central section of a printing head. CONSTITUTION:A control section 4 recognizes the presence of an ink ribbon by the signal of a reflection type photosensor 1 positioned near the nose of the central section of a printing head 3 on printing.

Title: Oil and water separating material
Inventor: SHIOZAWA MASATATSU
IPC: B01J20/24
Filed: 1992-11-06
Abstract: PURPOSE:To provide oil and water separating material capable of recovering oil by passing waste water through a mat constituted of cloth containing collagen fiber. CONSTITUTION:Oil and water separating material is produced from cloth containing collagen fiber as follows. Dispersion liquid is produced by adding 5-40wt.% collagen fiber to a dimethylformamide solution of a binder composition which consists of 10 pts.wt. polyurethane elastomer and 30-40 pts.wt. natural or synthetic rubber. Base material is coated or impregnated with the dispersion liquid and thereafter dried. The surface is buffed to expose collagen fiber to the surface. Further as the other producing method, collagen fiber is spun or woven together with the other fiber for forming the base material. Collagen fiber and the other fiber are simultaneously used in nonwoven fabric forming process and may be formed into nonwoven fabric. It is preferable that collagen fiber is chemically modified with a fish oil oxide. Regeneration of the oil and water separating material produced in such a way is achieved only by washing the same with gasoline. Therefore regeneration cost is made extremely inexpensive.

CONSTITUTION:Manganese zinc ferrite is obtained at an atmospheric pressure by preparing a solution comprising manganese sulfate, zinc sulfate, and ferric sulfate, under a coprecipitation condition; pH10-13, 80 deg.-100 deg.C. In such a case, wet-system ferrite has a composition formula which is expressed by (MnO)X.(ZnO)Y.(Fe2O3)Z where its composition range is 0.35<=x<=0.47, 0.12<=y<=0.24, 0.36<=z<=0.46, x+y+z=1. Then, the rate of its magnetization change in the vicinity of a room temperature is extremely large and meets the conditions required as a magnetic fluid. After coating the surfaces of these wet-system ferrite particulates with an inter-facial active agent, the magnetic fluid is obtained by a well-known method.
