Title: Rotary engine utilizing circulatory cylinder
Inventor: FUKUSHI JIYUNICHI
IPC: F02B53/00
Filed: 1982-08-17
Abstract: PURPOSE:To rotate a rotor efficiently, by circulating pistons in a circulatory cylinder. CONSTITUTION:Pistons 2-1, 2-2 are formed in a circular cylindrical shape so bent that they can be moved in the circulatory cylinder 1, and a movably-type pin 4 protruded to the outside is provided at the center of each of the pistons. When a gaseous mixture is exploded by an ignition plug 5, the pin 4 of the piston 2-2 is moved to the inside, is fitted into a groove 6 of the rotor 3, and rotates the rotor 3. At this moment, used exhaust gases are discharged through an exhaust port 7. When the piston 2-2 passes by the exhaust port 7, the gaseous mixture is introduced through an intake port 8, the piston 2-2 compresses the gas, and simultaneously pushes the piston 2-1. When the pin 4 of the piston 2-2 comes to a position in proximity to the groove 9 of the cylinder 1, the pin 4 is protruded to the outside, and explosion is repeated. Accordingly, the rotor 3 can be rotated efficiently.

Title: Flatness-retainig method of wall face of vacuum heat-insulating box
Inventor: YAMAJI TADAO
IPC: B65D81/38
Filed: 1992-06-04
Abstract: PURPOSE:To prevent the inner faces of a box from deforming and getting in contact with the contents when heating the articles contained in a vacuum heat-insulating box or retaining the temperature thereof. CONSTITUTION:When the inside of inner box 11 is heated, a double-wall 13 is prevented from denting inward due to the thermal deformation to keep the flatness of the double-wall 13, by pressurizing the inside of inner box 11 to swell out the double-wall 13. In this way, the wall faces of inner box 11 are prevented from getting in contact with the contents due to the thermal deformation. Accordingly, it is not necessary to make larger a vacuum heat-insulating box to avoid such contact.

Title: Air-fuel ratio control for carburetor
Inventor: IWAKURA YOICHI
IPC: F02M7/24
Filed: 1985-06-29
Abstract: PURPOSE:To stabilize engine revolution when vapor is produced in a carburetor and instability of engie revolution is sensed with a rough idling sensing means by retaining the opening of a flow rate control valve of an air bleed passage in a fuel-rich side retention position. CONSTITUTION:In the captioned device, a flow rate control valve 8 for opening and closing air bleed passages 6 and 7 of a carburetor 1 is opened and closed by means of a feedback control means A based on signals from an O2 sensor 14 for sensing O2 concentration in the exhaust so that the air-fuel ratio of the mixture is feedback-controlled to a specificed value. In this case, if the engine revolution becomes unstable due to causes such as the engine being left in a hot atmosphere and vapor being produced in the carburetor 1, output of the O2 sensor 14 fructuates rapidly. This condition is corrected with the said feedback control by sensing the condition by means of a rough idling sensing means B. Then the opening of the flow rate control valve 8 is made to be retained in a specified fuel-rich side retention position by means of a rough idling time control means C.

Title: Leading-out groove detecting circuit of record player
Inventor: HIROTA YOSHIHISA
IPC: B29L22/00
Filed: 1980-09-11
Abstract: PURPOSE: To prevent a detection error even in case when a record is eccentric, by outputting a detecting signal when the sum total in 1 rotation of a record, in which a signal level being proportional to rotation of a tone arm exceeds a prescribed reference level, has exceeded a prescribed reference time.  
     CONSTITUTION: In case when a record is eccentric, the time when a comparison output is generated from the first comparator 2, that it to say, the time when a speed of a tone arm exceeds a reference speed is a part of 1 rotation of the record, also the speed of the tone arm is reversed against the tracing direction as the case may be when it enters a leading-out groove, therefore, on the contrary, the speed of the tone arm becomes lower than the reference speed in some case. This lowered time, however, is less than the time required for half-rotation of the record. Accordingly, when a reference count value of the second comparator 34 is set, for instance, so as to correspond to the time required for half-rotation of the record, no detection error occurs even if the record is eccentric. According to such constitution, a detection error is prevented.
