Title: Magnetic head
Inventor: SOEDA HARUO
IPC: G11B5/187
Filed: 1985-06-17
Abstract: PURPOSE:To record and reproduce satisfactorily a picture with less noises by setting the radius of curvature of a tip part facing a regulating plate by holding a driving the rotating magnetic disk within a range from 3-16mm. CONSTITUTION:When the S/N of picture quality is set more than 43dB as preferable recording and reproducing conditions at the time of applying the titled head to a video floppy, it is necessary that the ratio (maximum/minimum output ratio)of the maximum and minimum amplitudes of a recording and reproducing waveform is set more than about 0.7. A relative moving speed between the video floppy 1 and a magnetic head 2 is set about 7.5m per sec in the outer-most periphery of the video floppy 1, and the relationship between the maximum/ minimum output ratio and the radius of curvature R of the tip part of the magnetic head 2 is obtained. From the result the maximum value of the radius of curvature R comes to 16mm. When a change in the radius of curvature R together with the use of the magnetic head 2 is experimentally obtained, the radius of curvature R before usage exceeds 3mm. Thus the picture can be satisfactorily recorded and reproduced.

Abstract: PURPOSE:To lengthen the service life and to improve the accuracy by rotatively driving a center valve based on the temperature difference between a mixed hot water and a set level and regulating the quantities of cold and hot water being fed into a mixing chamber of an upper valve. CONSTITUTION:When a center valve 25 is in a neutral position, a cold water path 25a and a hot water path 25b are communicated with substantially same opening to a recess 31a of an upper valve 31, but when the center valve 25 rotates to the right and left, the mutually communicated openings vary in the opposite directions. The temperature of mixed hot water is detected by means of a temperature sensor 35 and compared with a setting level to produce a difference which is employed together with its polarity for rotating a motor 27 forwardly or rearwardly. The center valve 25 is rotatively driven by said motor so as to regulate the quantities of cold and hot water being fed into a mixing chamber 31a of the upper valve 31 thus maintaining the temperature of the mixed hot water at the setting level.

Title: Variable compression ratio engine
Inventor: HORI KENJI
IPC: F16M1/021
Filed: 1983-07-18
Abstract: PURPOSE:To obtain a variable compression ratio engine which is simple in structure and excellent in durability and reliability, by connecting a cylinder block and a crankcase or the like by the intermediary of a shape memory alloy that is expansible in the axial direction of a cylinder. CONSTITUTION:A shape memory alloy 1 is fixed between the lower portion of flange 3 formed to extend outward from the lower outer wall of a cylinder block 2 of an engine and the top 4a of a crankcase 4 respectively by means of bolts 5, 6. The shape memory alloy 1 is so designed that it is expanded when the temperature is higher than the critical temperature and contracted when the temperature is lower than the critical temperature. With such an arrangement, it is enabled to increase the compression ratio at the time of starting the engine by making the shape memory alloy 1 take its low-temperature shape. On the other hand, when warmingup of the engine is completed, the compression ratio is lowered to such an extent as not to cause knocking by making the shape memory alloy 1 take its high-temperature shape.
