Title: Development device
Inventor: MIYAGAWA NOBUHIRO
IPC: G03G15/00
Filed: 1980-09-19
Abstract: PURPOSE: To prevent a fogging phenomenon completely even in variable copying conditions, by providing a means of applying a development bias which is controlled according to the signal of a sensor detecting the humidity of a photoreceptor surface.  
     CONSTITUTION: A potential at a connection point P 1  between a fixed resistance r 1  and a variable resistance r 2  is set in a comparator C previously and them compared with that at the connection point P 2  of a sensor H to control a driving circuit A 2 . At this time, a developing device 4 is applied with a bias between a DC power source E 1  and a DC power source E 2 . When the potential on the connection point P 2  exceeds the set value, a TR is turned on and a relay is energized with a signal from the comparator C to break a relay contact R 1-1  to apply the bias voltage of only the power source E 1  to the device 4. Consequently, fogging due to variations in humidity is prevented to obtain invariably clear pictures.

Title: Easily separable working base on sea
Inventor: FUJITA HIDEO
IPC: E02B17/04
Filed: 1979-10-11
Abstract: PURPOSE: To secure the support of leg on soft ground as well as make easier the drawing of the leg by providing a valve device closing when the leg is thrust into the soft ground at seabed but opening when the leg is drawn out of the soft ground at the lower end of the leg of a marine working base.  
     CONSTITUTION: In case where a bottomed type marine working base is set in place at seabed, a leg 10 connected to the lower part of the working base is lowered by an elevator device not illustrated, and when the leg 10 reaches the soil at seabed, a valve device 15 housed in a housing 14 at the lower end of the leg 10 is pushed up by a soil pressure 18 to close the upper part of a groove 19 of a constricted form. Thus, the incoming of mud into a water trap 20 is prevented, forming a resistor against the soil pressure. On the other hand, when pulling up the leg 10, a negative pressure is exerted between the mud and the back side of the leg 10 and thereby the valve device 15 is relatively pulled down to an edge portion 16. Thus, water in the water trap 20 flows in the direction of arrows 21, the adsorptive force of the mud is lost, and the leg 10 can be easily drawn out.

Title: Method and device for converting rotary motion into rotary vibrating motion
Inventor: TOZAKI CHIKAO
IPC: G01N11/16
Filed: 1980-09-20
Abstract: PURPOSE: To make the vibration of a shaft to be driven to be completely symmetrical and highly approximate to the sinusoidal wave, by vibrating said shaft perpendicularly crossing with the drive shaft through an intermediate arm performing the conical motion due to the rotation of the drive shaft.  
     CONSTITUTION: Upon the rotation of a drive shaft 9, the center line of an intermediate arm 13 will perform the conical motion where the circle described by a coupling section 14 is the bottom circle while the cross-point is the top point. Said motion is transmitted through couping sections 15, 16 and an arm 11 to a shaft 8 to be driven, but since the vertical component is absorbed by the free rotation around the coupling sections 15, 16 only the horizontal component is transmitted. In order word the vibration having the amplitude which is the half of the top angle of said conic is transmitted to said shaft 8. Consequently the vibrating waveform of said shaft 8 will be approximately sinusoidal having complete symmetry.

Title: Recording head
Inventor: NAKAGIRI TAKASHI
IPC: B41J2/055
Filed: 1977-10-31
Abstract: PURPOSE:To improve the generating effects of a recording medium by forming a discharge passage from a recording medium chamber through the wall of the medium chamber which is equipped with volume varying means of the medium chamber. CONSTITUTION:If a recording medium is supplied to a recording head 11, it flows out through a passage 12. In order that the redording medium stored in its chamber 14 may be discharge from a discharge orifice 15, impulses of suitable frequency are fed through lead electrodes 21 and 22 to an electric-mechanical converter 16. When this converter vibrates, the wall 17 itself of the medium chamber 14 including a discharge passage 13 is vibrated so that the recording medium is effectively cut, when it is discharged from the orifice 15, by the mechanical force resulting from those vibrations. Thus, the generating efficiency of the recording medium droplets can be improved. Moreover, sufficient follow can be ensured even if the frequency of the electric impulses is increased.

Title: Mold in continuous casting machine
Inventor: OZEKI AKIYA
IPC: B22D11/04
Filed: 1979-10-13
Abstract: PURPOSE: To decrease the tensile stress on the top face side of an ingot and enable the cracking under the surface layer to be prevented by specifying the ratio of the width of the top surface of the ingot and the width of the under surface of the ingot with respect to the thickness of the ingot in the sectional shape of a mold.  
     CONSTITUTION: The mold is so formed that its sectional shape has the relation shown by the formula where the width of the top surface of an ingot is defined as lu, the width of the under surface of the mold surface le, the thickness of the ingot (t), and the maximum bending radius of the ingot R. If this mold is used, the ingot surfaces are restrained by the pressing force of upper and lower rolls at the ingot leveling point of a continuous casting machine; therefore the top surface width of the ingot does not become narrow and the under surface width does not become wide either. Hence, the tensile stress distribution on the ingot top surface side decreases and the ingot of decreased cracking under the top layer and surface layer is obtained.
