IPC: F02F7/00
Filed: 1997-06-27
Abstract: PROBLEM TO BE SOLVED: To provide a crosshead for crosshead type two-cycle internal combustion engine, capable of lowering the height of an engine structure without altering any size of this crosshead, or guide shoe's sliding surface, and this engine itself. SOLUTION: A vertical distance A ranging from a lower end 10 of a sliding surface 4 of a crosshead to an axis 12 of this crosshead is shorter than a vertical distance B ranging from the axis of the crosshead to an upper end of the sliding surface, and the axis is set up in a distance 16 shifted downward from an intermediate 15 of the sliding surface without altering its size. Since a distance ranging from the lower end of a guide to a crankshaft is nonvariant, a connecting rod becomes shortened as far as a portion corresponding to the distance of the axis of the crosshead, therefore the structural height of an engine can be lowered. In a from of one execution, a guide shoe 1 pivoted on a crosshead pin is installed there, and a bearing 3 to this pin is in a distance shifted from the intermediate of this guide shoe in parallel with the sliding surface.  This guide shoe is desirable to be divided within a vertical surface 11 to the working direction.

Title: Controlling device for humidity
Inventor: SAKATA KEIKI
IPC: F24F11/02
Filed: 1980-12-05
Abstract: PURPOSE: To perform a high accurate control over a humidity by a method wherein a  sensed humidity and a plurality of predetermined levels are compared so as to judge  the sensed humidity corresponds to which humidity range, and a dehumidification signal  and a humidifying instruction signal, and a dehumidification stopping signal and a  humidifying terminating instruction signal are produced in response to the result of  judgement.  
     CONSTITUTION: Under a high humidity condition, a resistance value of a humidity sensing element 1 is decreased and a voltage V i  is increased more than a voltage V a  at a  connection point (a). Thus, the outputs from the comparators 6W8 are set to "1" and a  high humidity range is sensed, FF circuits 21,22 are set, a dehumidifying instruction  signal is produced at an output terminal of the circuit 21 and a humidifying termination  instruction signal is produced at the output terminal of the circuit 20. In this way, a  dehumidifying operation is performed, the voltage V i  is decreased as a humidity is  decreased and when it is lower than the voltage V a , only an output from the comparator 6 becomes "0" and a medium humidity range is detected. Then, when the voltage  V i  is lower than a voltage V i  at the connection point (b), a low humidity range is  sensed and then a dehumidifying termination instruction signal is produced from the  circuit 21.

Filed: 1993-07-12
Abstract: PURPOSE:To reduce the rate of jitter contained in a reproduced signal by specifying the relation between the extinction coefft. and refractive index of a material forming the reflecting layer of a phase change type optical disk with a recording layer and the reflecting layer on the substrate. CONSTITUTION:A recording layer 3 of a material causing a crystalline- amorphous phase change in accordance with laser power for irradiation is formed on a transparent substrate 1 and a reflecting layer 5 is formed so that reflection is ensured between the recording layer 3 and the substrate 1. The reflecting layer 5 is made of a material satisfying the condition of k<=0.76n+1.8 [where (k) is extinction coefft. and (n) is refractive index] and Cr or Ni-40 atomic% Cr is used. Since the difference in the absorptivity of the recording layer 3 between an amorphous state and a crystalline state can be made as small as <=15%, the difference in the temp. rise profile of the recording layer 3 between parts made amorphous and crystalline is made small at the time of overwriting and the rate of jitter contained in a reproduced signal can be reduced.

Abstract: PURPOSE: To perform the feeding of recording paper having an arbitrary width smoothly by providing a back tension mechanism comprising a spring in a pair of tractors which can be locked at a specified position which is adjusted to the width of the paper.  
     CONSTITUTION: A pair of the tractors 4 are locked to a supporting shaft 12. A handling lever 6a is rotated counterclockwise in order to set the paper. Since the inner diameter of the rotary shaft 5 becomes large, the locked state of the shaft 12 is unlocked. At the same time an eccentric cylinder shaft 7 is rotated and a plate spring 10 is raised. Under this state the paper 2a is put into a paper guide 2, and set to the tractors 4 through a platen. Then the handling lever 6a is rotated clockwise, and the inner diameter 4 of the cylinder shaft 7 is contracted. Thereafter the tractors 4 are locked to the supporting shaft 12, and a pushing force is generated for the paper by the plate spring 10. In this constitution, since the pushing force is always generated at both ends of the paper regardless of the size of the paper, the accurate paper feeding can be performed to the printing position.
