Abstract: PURPOSE:To manufacture a titled cam shaft continuously, surely and easily by closely fitting a cam material pipe in a die provided with cam-shaped and bearing-shaped recessed grooves and forming a hardened layer on the projected face swelled out by explosion working. CONSTITUTION:A cam material pipe made of heated carbon steel is closely fitted to a cam material pipe receiving hole 1 in longitudinal direction of inner core of a forming die 5, and openings 7, 8 on both ends of the pipe are closed. Then, high pressure air from a high pressure air inlet pipe 11 is spouted into the pipe 6 through a spouting pipe 10 closely fitted to a through hole 9 of the die 5, and fuel of hydrocarbon group sent from a fuel sending pipe 12 is sent into the pipe 6 through the spouting pipe 10. The fuel is suddenly burnt and exploded by the heat of the pipe 6, and a cam projected face 13 and a bearing projected face 14 are formed along the cam-shaped recessed groove 3 and bearing-shaped recessed groove 4 in the die 5 by generated explosion pressure. Then, the pipe 6 is removed from the die 5, and after forming hardened layers 15, 16 on the projected faces 13, 14, outer faces of the layers 15, 16 are polished and shaped.

Title: Method for preventing rupture in continuous pipe making mill
Inventor: INOUE TAKESHI
IPC: B21B17/14
Filed: 1986-09-19
Abstract: PURPOSE:To suppress the rupture in a pipe making mill by changing the elongation rate in a reducer to a low prescribed value when a terminal welded part advances into rupture dangerous zones and resetting said value to the elongation rate at the time of ordinary pipe making when said part leaves the rupture dangerous zones. CONSTITUTION:The momentary position of the terminal weld zone is calculated and tracking is executed in a block 101. (b) Contacts 121b and 122b are opened and (a) contacts 123a are closed when judgement is made by such tracking that the terminal weld zone enters the rupture dangerous zones L1 and L2 in a judgement block 111. As a result, the thickness calculation on the outlet side of the reducer in a block 92, the elongation rate calculation of the reducer in a block 93 and the calculation of the rotating ratio of an additive motor to the main motor in a block 94 are stopped. The rupture dangerous one rotating ratio corresponding to the elongation rate of the specified value lower than the elongation rate at the time of ordinary pipe making is outputted to a block 95 from a block 102. The block 95 sets the rotating speeds of the main motor and additive motor in accordance with the rupture dangerous zone rotating ratio.

Abstract: PURPOSE:To reduce noises, to improve an S/N, to simplify constitution and to realize cost reduction by providing an LPF, high-frequency correcting circuit, and emphasis switching circuit. CONSTITUTION:A D-A conversion signal from a D-A converter which is not shown in a figure is supplied to an input terminal IN and passed through an integrator 11 and a sample holding circuit 12 to obtain an analog signal, which is supplied to the LPF21.

Title: Two-cycle engine provided with auxiliary piston
Inventor: KAJIYAMA SAKUJI
IPC: F02F1/22
Filed: 1982-12-22
Abstract: PURPOSE:To elevate an auxiliary piston, during upward stroke of a main piston, at an elevating speed higher than that of the main piston so that residual gas may be exhausted by the auxiliary piston. CONSTITUTION:When a main piston 2 comes to its bottom dead center, an auxiliary piston 6 is also positioned to its bottom dead center by its weight or the repulsion force of a return spring 13 so that an intake valve 20 and as well an exhaust valve 21 are opened. When a main piston 2 comes up, an intermittently reciprocating mechanism 9 pulls up the auxiliary piston 6 to its top dead center at a high speed. Since negative pressure is effected in an intake-air chamber so that air is sucked through an intake port 18, and positive pressure is effected in a combustion chamber 17, resulting in discharging of burnt gas through an exhaust port 19. Then, when the main piston further comes up while the intake valve 20 and the exhaust valve 21 are closed, positive pressure is effected in the intake-air chamber 16, and therefore, fresh air is introduced into the combustion chamber 17 through a check valve 15. When the main piston 2 comes to its top dead center, an ignition plug 2 is sparked. Therefore, both main piston 2 and auxiliary piston 6 are pressed downward to give a work to a crankshaft 4.

Title: Automatic wheelchair
Inventor: WAKAUMI HIROO
IPC: A61G5/04
Filed: 1988-09-06
Abstract: PURPOSE:To obtain an automatic wheelchair which eliminates the necessity of manipulation of a lever during running by allowing the wheelchair to automatically run along a guide and to have a nonlinearity so as to disable steering operation in a range with a small positional deviation from the guide. CONSTITUTION:When a running mode change-over switch 18 is turned to a sensor signal side and a wheelchair body is set on a guide marker 10, the distribution of magnetic flux which is produced by energizing an exciting circuit is varied by the marker 10. This variation is detected by detection coils L1, L2, and is taken out as a difference signal which is converted into a d.c. signal. This difference signal is delivered to a nonlinear amplifier 12 so as to obtain a signal by which a feed-back system control section detects a rotating angle of a steering motor 6 through an angle sensor while a current in accordance with a difference between the detected value and the output signal from the nonlinear amplifier 12 is fed to the steering motor. In this arrangement, there is carried out such a nonlinear motion that the steering motor 16 is not driven in a range with a small deviation of the wheelchair from the marker 10. Accordingly, it is possible to eliminate the necessity of manipulation of a lever.
