Title: 2-4 stroke switching engine
Inventor: MATSUOKA HIROSHI
IPC: F02B37/00
Filed: 1992-06-29
Abstract: PURPOSE:To obtain a 2-4 strokes switching engine which performs scavenging through a check valve of a scavenging port during 4-stroke operation, and improves heat efficiency. CONSTITUTION:An intake valve 4 arranged on an intake port 3 of a cylinder head 1 is held in a blocked condition during 2-stroke operation, and opened/ closed during 4-stroke operation, for performing intake. A check valve 28 provided on a scavenging port on a lower side of a cylinder 10 is opened in an initial period of an exhaust process of the 4-stroke operation. New air is sent into a cylinder for scavenging from a turbocharger 5 driven by an exchaust energy. The space inside the cylinder is forcibly scavenged in an exhaust process of the 4-stroke operation, so that an amount of the residual gas in the cylinder gets extremely small. The new air receives heat from a wall surface at the scavenging time in the 4-stroke operation, and energy is recovered by the turbocharger 5 and the like, and thus the heat efficiency is improved.

Abstract: PURPOSE:To measure the thickness of the snow stuck to an underfloor apparatus or the like when a train is traveled without requiring much labor and cost by setting light beams at the heights of the lower sections of wheels and the underfloor apparatus in the direction perpendicular to a railway. CONSTITUTION:A light beam 3 set at the height of an underfloor apparatus 5 and a light beam 4 set at the height of the lower sections of wheels 6 are radiated from a light emitting unit to a light receiving unit on the opposite side of a railway. The lower section of the wheel 6 interrupts the light beam 4, and the time until the vehicle 6 passes through the position of the light beam 4 can be known. The speed of a train is obtained by the time after a prescribed wheel 6 passes until the next wheel 6 passes and the wheelbase of the wheels 6. The length of the underfloor apparatus 5 stuck with snow 7 is obtained by the time when the light beam 3 is interrupted by the underfloor apparatus 5 and the snow 7 stuck to it and the speed of the train. The length of the underfloor apparatus 5 is known, thus the thickness of the stuck snow 7 is obtained by the difference between the length of the floor apparatus 5 stuck with the snow 7 and the length of the underfloor apparatus 5.

Title: High definition television signal transmission system
Inventor: NINOMIYA YUICHI
IPC: H04N7/083
Filed: 1989-07-28
Abstract: PURPOSE:To attain compatibility with conventional transmission line equalization by increasing a VIT signal(Vertical Interval Test signal) more than a normal signal level periodically so as to realize the equalization of a high frequency large amplitude characteristic. CONSTITUTION:A VIT signal (referred to as a small amplitude VIT signal) of nearly the same degree of amplitude level as a video amplitude level is sent and a larger amplitude VIT signal than the small amplitude VIT signal replacing the small amplitude VIT signal periodically is sent. The large and small VIT signals being output signals of a VIT signal extraction circuit 2 are decided for the quantity by the logic of an iteration flag detected by a control signal detection circuit 3 separately. That is, in the case of logical 0, an output from a quantity discrimination circuit 4 is handled as the small amplitude VIT signal and in the case of logical 1, an output from the circuit 4 is handled as the large amplitude VIT signal. Thus, the equalization of the large amplitude characteristic is implemented in addition to the equalization of the conventional small amplitude characteristic.

Abstract: PURPOSE:To improve performance by adding lime, silica sand, etc., to the incinerated ash of sewage sludge, specifying the ratio of calcium/silicon, adding an epoxy resin to globular slag obtained by crushing the melt by air and kneading and molding the slag. CONSTITUTION:Lime, silica sand, brick chips, LD slag, etc., are added to the incinerated ash of sewage sludge, and the ratio of calcium/silicon is brought to 1.0-2.0 at the conversion ratio of CaO/SiO2. The melt is crushed by high-speed air, thus forming globular air-crushed slag. The dye and pigment of an inorganic group, etc., and a polyvinyl alcohol derivative having an SiO2 reactive group shown in formula I are prepared. In formula, X, X<1> and X<2> represent an alkyl group, a hydrogen atom, a potassium atom, a sodium atom and an ammonium group. An epoxy resin is added to these substances, thus forming a proper quantity of inter-grain air gaps. The kneaded substance is poured into forms or spread all over a subbase course and rolled, and covered with a sheet for approximately twenty-four hours and cured, thus forming a color pavement slab. Accordingly, appearance, strength and water permeability can be improved while environmental contamination such as heavy metal eluation can be prevented, and incinerated ash can be utilized effectively.
