Title: Die casting machine for cylinder for two cycle engine
Inventor: HATTORI MASAAKI
IPC: B22D17/22
Filed: 1987-10-12
Abstract: PURPOSE:To cast the cylinder for two cycle engine equipped with a partition wall by integrally forming a pair of projection parts at intervals in the space with the outer peripheral face of the tip of a core part on the tip of the outer peripheral part of a sliding core. CONSTITUTION:A partition wall is formed between a scavenge air passage and cylinder face by a gap 27 when a molten metal is injected and the cylinder for two cycle engine on which an exhaust port is formed by a core 30 with slide is cast. A movable die 11 is then separated from fixed die 10 and when a slide key 35 is moved in the reverse direction, the core 30 with slide is released from the exhaust port by the action of a cam groove 36 and retreated to the retreating position becoming of the inner side than the outer peripheral face of a core part 25. When a sliding core 20 is retreated in this state, the sliding core 20 is pulled out without the sliding entry core 30 forming the exhaust port interfering with the partition wall and the cast cylinder for two cycle engine can be taken off.

Abstract: PROBLEM TO BE SOLVED: To curtail a time necessary for solidifying a cylindrical polyamide acid film and to provide the cylindrical polyamide acid film having improved adhesion between layers of the film and another cylindrical film. SOLUTION: A cylindrical polyimide film is formed by passing through a process in which a cylindrical liquid film of a polyimide acid solution is formed on the inner surface of a cylindrical molding mold, a process in which 50-90% of the solvent of the cylindrical liquid film of the polyamide acid solution is extracted/removed by making the surface of the cylindrical liquid film of the polyamide acid solution get into contact with a solvent which has affinity with the solvent of the polyamide acid solution and does not dissolve the polyamide acid, and a process in which the cylindrical liquid film of the polyamide acid solution from which the solvent wax extracted is heated to remove the residual solvent and to convert the polyamide acid into the corresponding polyimide in turn.  A cylindrical thermosetting resin film, a cylindrical thermoplastic resin film, or a cylindrical polyimide film is formed on the inner surface of the formed cylindrical polyimide film.

Title: Unmanned vehicle
Inventor: ODANI MASAHIRO
IPC: A63B55/60
Filed: 1991-09-10
Abstract: PURPOSE:To smoothly start the radio travel engine drive type unmanned vehicle on a slope. CONSTITUTION:The car body is equipped with a radio drive type traveling device to start/stop this car body and a steering device to turn front wheels 3 along a guide line. The traveling device is equipped with a start operation control means. When executing a start operation, an electromagnetic brake 28 is turned to a braked state until the number of engine rotations reaches a link rotation number for linking a centrifugal clutch. After the number of engine rotations reaches the link rotation number, the electromagnetic brake 28 is turned to a non-braked state. Therefore, since the brake of rear wheels 4 is canceled after motive force is transmitted to the rear wheels 4, the rear wheels 4 are rotationally driven by an engine 25 simultaneously with the brake cancel.

Title: Error discriminating circuit
Inventor: KANAI KIYOSHI
IPC: G09G5/00
Filed: 1992-09-02
Abstract: PURPOSE:To provide an error discriminating circuit which can surely discriminate the types of errors and also can shorten the fault restoring time. CONSTITUTION:Either one of four error signals Sa, Sb, Sc and Sd is inputted to either one of four information mask circuits 1a-1b. Thus either one of these circuits 1a-1d to which the first error signal inputted outputs this signal as it is. However other mask circuits have the logic value '0' by the influence of the mask circuit where the error signal is first outputted by the input of AND circuits 1a-1d connected to the inverter circuits 4a-4d. Therefore the mask circuits of logic value '0' output no error signal if inputted. As a result, only one of those signals Sa-Sd that is first inputted is outputted.
