Inventor: MITANI TOMOMI
IPC: A47L9/00
Filed: 1992-06-15
Abstract: PURPOSE:To provide a vacuum cleaner in which the buffer effect is improved in simple manner by installing a bumper utilizing exhaust gas. CONSTITUTION:A bumper 6 which has a nearly U shaped section and is engaged at the peripheral, part is installed, keeping a distance from the part 8 faced to an exhaust hole 7 on a body 1, and the exhaust hole 7 of the body 1 and the through hole 9 of the bumper 6 are formed with a mutual positional deflection. Accordingly, the exhaust gas discharged from the exhaust hole 7 is discharged outside from the through hole 9, passing through the space 10 between the body 1 and the part 8 faced to the exhaust hole 7. The space 10 serves as the bumper for the gas due to the exhaust, and the bumper on which exhaust gas collides secures the high buffer effect due to the exhaust gas heat.

IPC: F01L1/34
Filed: 1978-12-18
Abstract: PURPOSE:To obtain an optimal valve overlap with ease, by providing a means for turning a valve and shroud means for changing the valve opening area at the same vlave lift in relation to turning angle of the valve. CONSTITUTION:On the upper surface of intake valve 1, there is provided valve shroud 2 whose height is changed along the circumference of valve 1. Similar seat shroud 4 is formed at the portion of valve seat but its disposition is reverse to that of the valve shroud 2. During low-speed operation of engine when pressure of engine oil is low, intake valve 1 is turned around its axis to a position where higher portion (a) of valve shroud 2 is aligned with portion (b) of seat shroud 4 where shroud height is substantially zero, as shown at (A) in the drawing, so as to reduce opening area of intake valve 1 more promptly and to thereby make earlier the time instant for cloping the valve at the intake. Thus, it is enabled to prevent back flow of exhaust gas to the intake system. At the time of raising revolutional speed of engine, on the other hand, intake valve 1 is turned 180 degrees to the position shown at (B) in the drawing, so as to increase valve overlap.

Title: Production of 2,6-dimethylnaphthalene
Inventor: SUMITANI KOJI
IPC: C07C6/12
Filed: 1990-06-15
Abstract: PURPOSE:To obtain the subject substance by transmethylating naphthalene in the presence of dimethylnaphthalenes, producing the monomethyl derivative, simultaneously isomerizing the dimethyl derivative, methylating the monomethyl derivative separated from the reaction mixture and then separating the subject substance. CONSTITUTION:Naphthalene is transmethylated in the presence of dimethylnaphthalenes (DMN) to produce monomethylnaphthalenes (MMN) and simultaneously isomerize the DMN (at 300-480 deg.C under ordinary pressure to 10atm). Thereby, DMN enriched with the 2,6-DMN and MMN are produced. The resultant product is then separated into naphthalenes, MMN and DMN to methylate the MMN with a transmethylating agent (e.g. xylene) and produce the DMN. Separation into the unreacted MMN, DMN and unreacted transmethylating agent is then carried out. The 2,6-DMN is subsequently separated and recovered from the DMN obtained in the aforementioned two steps. Thereby, the loss of methyl groups is reduced to provide the useful by-products by using the xylenes. As a result, the objective substance is efficiently produced.

Title: Air-fuel ratio controller for internal-combustion engine
Inventor: KITAHARA TAKESHI
IPC: F02D41/00
Filed: 1984-07-27
Abstract: PURPOSE:To early eliminate the deterioration of operation performance or exhaust gas quality, by providing an abnormality judgment means for judging, on the basis of a value detected by an air-fuel ratio detection means, whether a fuel supply system is abnormal or not. CONSTITUTION:An air-fuel ratio sensor 1 continuously detects the air-fuel ratio of an internal-combustion engine within a prescribed range in terms of the concentration of oxygen in the exhaust passaage of the engine. An air-fuel ratio correction coefficient determining section 50 outputs an air-fuel ratio correction coefficient alpha to a air-fuel ratio feedback corresponding section 44 which corrects the quantity of supplied fuel to contol the air-fuel ratio to an aimed value by feedback. On the basis of the result of the detection by the air-fuel ratio sensor 1, an abnormality judgment circuit 56 judges whether a fuel supply system is abnormal or not. The result of the judgment is indicated by an abnormality indication lamp 57. This results in early eliminating the deterioration of operation performance or exhuast gas quality.

Title: Dielectric loss tangent measurement
Inventor: AIHARA MITSUGI
IPC: G01R27/26
Filed: 1978-12-13
Abstract: PURPOSE: To accomplish the measurement of the dielectric loss tangent free from the effect of induced disturbance by applying a voltage from a half-wave rectification of a sine wave to the intended measuring signal.  
     CONSTITUTION: When a half-rectifying voltage V is applied to the intended measuring material as indicated by an equivalent circuit, a current i flows through the measuring material in the sum of the current iR running through an equivalent resistance Rx and the current iC through an equivalent capacitance Cx. At this point, the mean value of the current i is determined and divided by the mean value of the current i after the full-wave rectification thereof to determine the dielectric loss tangent value. On the other hand, the mean value of the current value flowing through the measuring material is reduced to zero due to the voltage incurred by the electrostatic induction and the electromagnetic induction. Therefore, the dielectric loss tangent value of the measuring material can be measured without being affected by such induced voltage.

This time difference is inputted to a counter 15 and processed together with the input from a clock circuit generating circuit 14 to measure the necessary time width. Then, this count result is inputted to a decimal counter 16, and counted as the distance and displayed 17.

Abstract: PURPOSE:To prevent a heat loss and welding thermal stress concentration by fixing heat-insulating lugs at predetermined spaces along the circumferential direction of the upper part of a tank, by causing suspension rods, which are coupled to the lugs to hang down, to hold heat-insulating backing rings, further causing the rods and rings to hold each other successively and by mounting heat insulators to the rings. CONSTITUTION:Heat-insulating Jugs 2 are welded to the upper part of the outer peripheral wall of a tank body 1 at suitable spaces circumferentially, suspension rods 3 are coupled to the lugs to hang down, and a heat-insulating backing ring 4 with L- shaped cross section is laid between adjacent two suspension rods 3. The next rod 3 is coupled to both ends of the heat-insulating backing ring 4 to hang down and this process is repeated successively so that the heat-insulating backing rings 4 are suspended and held up to the position of the lower part of the tank body 1. A panel- shaped heat insulator 5 is arranged between a pair of upper and lower heat-insulating backing rings 4 and the surface of the heat insulator is covered with a protective member 6, which is fixed to the heat-insulating backing ring 4. Thus, the welded place of the heat-insulating lug is reduced, the thermal stress concentration to the welded part is prevented and the expansion and contraction of the tank body 1 is protected by the heat insulator from suffering restriction.
