Title: Image pickup device
Inventor: SHINTANI AKIRA
IPC: H04N5/228
Filed: 1980-12-24
Abstract: PURPOSE:To obtain an image pickup device where the output capacity is small and the beam shading does not occur, by floating electrically the target ring during the reflection time and by grounding the target ring during the beam blanking time. CONSTITUTION:A switching element synchronized with a vertical synchronizing signal is connected between a target ring 6 and the earth. Consequently, the target ring 6 is opened in the time till the fall of the vertical synchronizing signal  pulse; and when the vertical synchronizing signal falls, the switching element is  turned on to ground the target ring 6. This operation is repeated to discharge  the charge, which is charged in the target ring 6, once per 60sec, thus preventing the beam shading which is caused by opening of the target ring.

Title: Magnetic recording medium
Inventor: SAKAI IKUO
IPC: G11B5/73
Filed: 1985-08-20
Abstract: PURPOSE:To obtain a magnetic recording medium of a thin metallic film type which is free from curling and is flat by forming a nonmagnetic metallic layer consisting of Mo between a magnetic metallic layer and substrate and generating cracks to relieve the stress between the metallic layer and the substrate. CONSTITUTION:A polyester film is used as the substrate 10. Molybdenum is continuously formed by a sputtering method as the nonmagnetic metallic layer 11 and a CoCr alloy as the magnetic metallic layer 12. The sizes of the cracks to be generated in the film thickness of the nonmagnetic metallic Mo layer 11 when the magnetic recording medium is manufactured are, for example; 50mum crack size when the film thickness of the nonmagnetic metallic Mo layer is 2,000Angstrom , 25mum when 1,000Angstrom  and no cracks are generated when the film thickness of an nonmagnetic metallic Mo layer 11 is smaller than 1,000Angstrom . The Mo begins to crystallize when the film thickness is >=1,000Angstrom . Then the Mo metal hardness and becomes brittle to the tension exerted thereto, thus generating the cracks in the layer 11. The stress accumulated between the polyester film substrate 10 and the nonmagnetic metallic Mo layer 11 is thereby relieved.

Filed: 1980-12-22
Abstract: PURPOSE:To avoid the wavy curling of the thin copy paper, by properly selecting and regulating a guide angle formed by the position where a contact is obtained between a separating pawl of the pressure roller side and the roller and the roller tangent line. CONSTITUTION:Separating pawls 6 and 7 are pressed to a heat roller 1 and a press roller 4 respectively. The wavy curling occurs to the thin copy paper 8 during a distance L between the passing point of the paper 8 through a contact between the tips of the pawl 7 and the surface of the roller 4 after the paper 8 passes the contact width of the roller. This curling can be avoided by reducing the distance L as small as possible. The distance L has its own limit, and it is difficult to reduce the distance <=5mm.. Thus the distance L is preferable with a value <6.5mm.. It is preferably set at >=45 deg. for the angle theta which is formed by the upper fringe forming the tip part of the pawl 7 and the roller tangent line.

Abstract: PURPOSE:To avert unnecessary reflection of light at a hinge or the fixing part thereof and to ameliorate degradation in contrast, etc., by applying an antireflection measure on at least either of the surface of this hinge or the fixing part surface of the hinge, thereby constituting the optical modulator. CONSTITUTION:A micromirror M is supported by the hinge 12 consisting of a band-shaped metallic thin film spanned between fixing parts 11 arranged by maintaining a prescribed spacing.

An arithemetic unit 7a compares the voltage in an output controller 31 with the output in a detector 6 to control a current source 8. The output in the controller 31 is compared 33 with a reference voltage 32 and if the output is higher than a reference value, the switch 30 is closed. The switch 30 is opened at output Ps along two-section discharge characteristics P1 by successively reducing the output in the controller 31 from a maximum value ad the output is stably supplied at the minimum output P2min along one-section characteristics P2. In this way, the output can continuously be controlled over a wide range and with stability. When two discharge regions exist, the maximum-to-minimum output ratio of 100:1 or over can be obtained.

Abstract: PURPOSE:To detect a human body stably over the range of 360 deg. by securing a human body sensor to the clock body, and rotating a reflector constantly in one direction to enter the infrared rays from a human body into the human body sensor, thereby avoiding the failure due to contact of the movable part and a connection wire. CONSTITUTION:A reflector 8 is rotated constantly in one direction through a drive section 10 to direct the infrared rays from a human body toward a human body sensor 2 secured to a clock body 4. A detection circuit 12 detects a human body over the range of 360 deg. based on an output signal from the sensor 2 and delivers a detection signal. When the surroundings is bright, an AND gate 18 is opened by a signal from a brightness sensor 16 and a detection signal is applied to the input 10 of a simulation sound IC 26. Consequently, the IC 26 produces a note of bird which is delivered from a speaker 30. When the surroundings is dark, an AND gate 22 is opened and a detection signal is applied to the input 11 of the IC 26 thus producing the chirps of a cricket. Since the connection wires and the like are not wired at the rotary part, failure due to disconnection or twisting of the connection wires can be eliminated.
