Title: Cross head type internal-combustion engine
Inventor: SHIMODA KUNIHIKO
IPC: F02B75/02
Filed: 1981-09-08
Abstract: PURPOSE:To heighten the maximum pressure of combustion gas, by providing a lid for closing the bottom opening of the cylinder of a cross head type internal- combustion engine and connecting an air reservoir with a pressure chamber defined by the lid, cylinder liner and piston. CONSTITUTION:A lid 20 is fitted on the bottom opening of the cylinder liner 4 of an internal combustion engine and slidably and hermetically mounted on a piston rod 11 over a crosshead 10. A pressure chamber 23 is defined by the lid 20, the cylinder liner 4 and the bottom of a piston 7 and communicates with an air reservoir 22 through a pipe 21. The air reservoir 22 is connected to an air source through a pipe 24. After the starting of the engine, compressed air is supplied to the air reservoir 22 through the pipe 24 so that prescribed pressure is produced. As a result, the pressure Pc of the pressure chamber 23 acts to the piston 7 opposite the pressure P of combustion gas so that the force which acts to the engine parts is reduced. The maximum combustion pressure Pmax can be heightened by the reduction of the force.

Abstract: PURPOSE:To improve a winding utility rate and to improve efficiency by forming two low voltage tap winding which are to be connected in series for connection with a low-voltage coil for the highest voltage and to be connected in parallel for connection with the low-voltage coil for the lowest voltage. CONSTITUTION:A terminal (b) is connected to a terminal (c) at the time of highest voltage at low voltage side to form a series structure of tap winding 41, 42. Terminals (a), (c) are connected to terminals (b), (theta) at the time of lowest voltage at a low voltage side to form a parallel structure of tap windings 41, 42. The windings 41, 42, a low voltage main winding 3 and a high voltage winding 2 are wound sequentially in this order from inside a core leg 1. The windings 41, 42 are wound by axially associating simultaneously as one cylindrical winding. The voltages of the winding at low voltage side are set to (2V3-V1) at the winding 3 and to (V1-V2) at the windings 41, 42. Accordingly, it becomes (2V2-V1)+2(V1-V2)=V1 at the time of highest voltage, and (2 V2-V1)+(V1-V2)=V2 at the time of lowest voltage to obtain a predetermined voltage. Currents flows all the windings at the time of the highest voltage at the low voltage side and the lowest voltage, winding utility is improved with compact configuration and high efficiency.

Title: Light control type optical switch
Inventor: KAWAGUCHI TAKAO
IPC: G02B6/122
Filed: 1983-08-03
Abstract: PURPOSE:To improve the branching ratio and dimming ratio of the titled optical switch by forming PLZT thin film waveguides controlling waveguide light by using electric power generated by a photovoltaic film and transmitting the opti- cal wave reflected on a full reflection surface of a prism arranged on the waveguides to one waveguide. CONSTITUTION:An optical wave l5 reflected by the full reflection surface 41 formed by adhering the prism to the PLZT thin film waveguides 12, 13 is transmitted to the waveguide 12 by a TIR type switch constituted of the waveguides 12, 13 controlling the waveguide light by using electric power generated by the photovoltaic film 16. The optical wave l5 is sent to a taper-like gap 31 and then sent to a thin film 11 as evanescent light and the evanescent light is transmitted to a direction 42. Since the coupling method brings the prism 21 into contact with the thin film 11 at its thick point 43, a break or the like is not generated in the prism 21, so that proper contact is always obtained and high efficiency of transmission is obtained.

Title: System and apparatus for time division multiplex
Inventor: NAMIKI JUNJI
IPC: H04J3/00
Filed: 1986-06-19
Abstract: PURPOSE:To allow each earth station to change a sent burst length properly in response to its own traffic by shifting each burst included in a burst string at each prescribed period by a head burst length in the forward direction while the relation of preceding/succeeding bursts is kept unchanged and changing its own burst length of the burst moved to the tail end. CONSTITUTION:Data bursts 10-13 are being shifted at each burst in the forward direction without losing the relation of preceding/succeeding bursts at each prescribed period T. Since only the burst length at the former position in each burst has only to be shifted forward, the control is very simple. On the other hand, since an idle slot exists after the tail end of the burst string, the burst moved to the tail end of the burst string at each shift is changed to expand or contract its own burst length and the generated idle slot is stored surely after the burst string. Since each burst comes to the tail end of the burst string without fail at a prescribed period T, its own burst length is changed freely at the period.
