Title: Exhaust gas suction muffler
Inventor: MORIOKA NORIO
IPC: F02B27/04
Filed: 1989-10-11
Abstract: PURPOSE:To prevent reduction of an engine output economize fuel consumption, and reduce exhaust noise during running, by providing a bevel fin on the end of an end exhaust pipe. CONSTITUTION:A bevel fin 8 is provided on the end of an end exhaust pipe 7 provided on the lowerstream of a muffler 2 to be fixed by a bevel fin guide 3. The lower part of the muffler 2 is covered with an air duct 6 provided with an air converging opening 5, and the bevel fin 8 is covered with a venturi tube 4 connected to the air duct 6. In such a structure, when an automobile runs, air coming from the air converging opening 5 is discharged backward, while sucking exhaust gas from an end exhaust pipe 7 by a venturi pipe phenomenon. Since ejecting resistance is reduced, an engine output becomes running force as it is so as to economize fuel consumption. Since the exhaust gas is sucked and diffused, it is possible to reduce exhaust noise doring running.

Title: Dye heat-transfer accepting sheet
Inventor: TOMIKANEHARA MASAHIRO
IPC: B41M5/382
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To facilitate the discrimination of the face and the rear, and the kind of a sheet by a method wherein on the rear surface of a dye heat-transfer sheet having an image accepting layer to accept a dye on one surface of a supporting body, a detection mark of which the optical reflection density is a specified value or lower, is provided. SOLUTION: The printing of a detection mark is performed in such a manner that the optical reflection density is 1.3-1.7, and also, 60 glossiness corresponding with JISZ8741 is 15% or lower. Since a reflection type sensor has a structure which senses a reflective light from an accepting sheet of a near infrared light which is cast by a light emitting unit, and it is different from a permeable type sensor, the detecting property is greatly affected not only by the mark printing density, but also the printing glossiness. A mark having an ideal detecting property in the reflection type sensor is one of which the printing density is high, also, which has a low glossiness, and can greatly attenuate the radiation light.  When the reflection density becomes higher than 1.7, the glossiness becomes easy to exceed 15%, and for this reason, the reflectance of the infrared light becomes higher, and a desired sensor detecting property cannot be obtained. Also, when the reflection density is 1.3 or lower, the detection becomes impossible as well.

Title: Paper sheet size detecting device
Inventor: SASAKI TOSHINORI
IPC: B41J13/00
Filed: 1991-10-15
Abstract: PURPOSE:To provide an inexpensive paper sheet size detecting device with improved reliability which is simply constituted, has less malfunctions, and is capable of accurate detection of the paper sheet size. CONSTITUTION:A resistor 39 is formed on the front surface of an arm 35 which interlocks with a widthwise guiding member 32, while a resistor 40 is formed on the back surface of an arm 37 which interlocks with a paper sheet supplying direction guiding member 32. The resistor 39 and the resistor 40 are in contact with each other in a crossed manner, constituting a variable resistor. The contact position of the resistors 39, 40 is different according to the movement of the widthwise guiding members 32, 33 and that of the paper-supplying direction guiding member 34, i.e., according to the paper sheet size. One end part of the resistor 39 makes a terminal (a) and one end part of the resistor 40 makes a terminal (b), and the resistance value between these terminals (a) and (b) is different according to the paper sheet size. Application of the constant voltage between these terminals leads to the change in the current value flowing in the constant resistor, and the change in the voltage value generated between both ends of this constant resistor enables discrimination of the paper sheet size.

Title: Image forming device
Inventor: FUJITA YOSHIO
IPC: G03G15/16
Filed: 1991-10-15
Abstract: PURPOSE:To stably separate a transfer sheet and to prevent toner from being attracted to a destaticizing means by bringing the destaticizing means into contact with a photosensitive drum and applying a voltage to a transfer roller for prescribed length of time. CONSTITUTION:Since the destaticizing means C is in contact with the photosensitive drum 31, the destaticizing means C is in secure contact with the sheet after transfer, and the destaticization of the sheet is securely performed. The destaticizing means C is composed of a flexible member, therefore it does not scratch the photosensitive drum 31 even when being in contact with the photosensitive drum 31. Additionally, a voltage is applied to the transfer roller 71 by an application control means 73 also during the prescribed times before and after the passing of the transfer sheet through a transfer position; therefore, toner is attracted to the transfer roller 71 before reaching the destaticizing means C even when a toner image on the photosensitive drum 31 and the transfer sheet are slightly displaced out of alignment in the transfer area and even when the toner is attracted to the part which is further downstream than the front end of the transfer sheet on the surface of the photosensitive drum 31 or the part which is further upstream than the rear end of the sheet.

Abstract: PURPOSE:To restrain the waste of a sample to the minimum upon the occurrence of an improper dispensing process by continuing transferring, dispensing, and analyzing processes until the time when an improper dispensing condition is continuously detected by the prescribed frequency or more, and then interrupting dispensing operation when the improper dispensing condition is so detected. CONSTITUTION:The nozzle 96 of a sample dispensing section 56 is moved to the position of the sample tank 16 of a cartridge 14, and the piston 106A of a syringe 106 is actuated along an arrow E direction, thereby gradually sucking a sample into the nozzle 96 and piping 98. Then, the nozzle 96 is moved to the positions of reaction tanks 20, 22 and 24, thereby dispensing the sample. In this case, a frequency where pressure detected by a pressure sensor 114 continuously gives values outside the prescribed range (improper dispensing condition) is counted, and a normal inspection process is continued until the time when the frequency reaches the prescribed level (approximately two to three times). When the improper dispensing condition is continuously detected by the prescribed frequency or more, the inspection process is stopped, and a sample dispensing process 56 and an analysis process at a measurement section are interrupted.
