Title: Optical scanning system
Inventor: SHIRAISHI TAKASHI
IPC: G02B26/10
Filed: 1987-05-01
Abstract: PURPOSE:To increase a recording form speed and also prevent stray light from appearing on an image without increasing the size of the whole optical system by arranging an optical system for reflection which allows light to be reflected at least twice by a rotary polygon mirror opposite a mirror surface of the rotary polygon mirror. CONSTITUTION:The optical system (reflecting mirror 4) for reflection is arranged opposite the rotary polygon mirror 3, which reflects the light at least twice. When the rotary polygon mirror 3 rotates by DELTAtheta, the projection light is deflected by DELTA4theta, so even when the number of surface of the rotary polygon mirror 3 is doubled, the same angle of deflection as usual is obtained. Consequently, the recording form speed can be made twice as fast as before. Further, a mirror surface surface of the rotary polygon mirror 3 and a scanning plane are not parallel, so even if stray light is reflected by the rotary polygon mirror 3, it deviates from the scanning plane and never appears on an image.

Title: Semiconductor integrated circuit device
Inventor: ASANO TETSUO
IPC: H01L27/02
Filed: 1984-05-29
Abstract: PURPOSE:To prevent electrostatic breakdown without affecting normal circuit operation by connecting a collector and an emitter in an NPN type transistor element formed in an island region electrically isolated from an island region, in which a PNP type transistor element is shaped, as a protective element between a base and a collector in the PNP type transistor element. CONSTITUTION:Input signals are transmitted over a PNP type transistor element 2 through a pad 3 from an external lead terminal 4. That is, input signals do not flow through an NPN type transistor element 5 because a base in the NPN type transistor element 5 is brought to a floating state in the NPN type transistor element 5 as a protective element. When surge voltage is applied to the external terminal, the PNP type transistor element 2 and the NPN type transistor element 5 as the protective element each share surge voltage, and both transistor elements 2, 5 mutually absorb surge voltage. Accordingly, since the transistor elements 2, 5 mutually absorb surge voltage, the junction area of a P-N junction is increased substantially, the withstanding voltage of reverse voltage is improved, and the breakdown of the elements is prevented.

Abstract: PURPOSE: To prevent mutual contamination of an evaporator in a downstream even if both evaporators attached to an anesthetic machine are out of order by including a contact surface always connected to an atmosphere in one part of a by-pass type controller of an anesthetic evaporator. CONSTITUTION: Carrier gas enters from an inlet 100 formed in a circular guide part 29 into an evaporator 20 and flows via a passage 101 into a recess 114. When a control valve 113 of the evaporator is in an OFF position, the recess 114 is connected via a pasasge 14, a valve 18, a chamber 21 and a passage 22 directly to an outlet 4. When the control valve 113 moves to an ON position, the recess 114 flows the gas via a passage 15, a valve 18, a passage 134, a circular groove 24 and a hole 25, as well as via the outlet 4, to form the evaporator. A part of the valve 113 is always connected to an atmosphere and grooves 102 and 103 are positioned between gaseous and vapor streams entering into the evaporator and passed from and to trucking regions.  Thus, even in the case that fine leakage crosses a contact surface 112a of a control valve 113, transferring vapor can be caught on the way and discharged via bores 122 and 123 and a passage 124 into an atmosphere.

Filed: 1986-05-12
Abstract: PURPOSE:To improve adhesion between a magnetic head, and the surface of a floppy disk, by protruding the slidable contact plane of a core part in the direction of a floppy disk plane rather than the direction of the slidable contact plane of a slider part. CONSTITUTION:To improve a recording and reproducing characteristics, a device is formed in such a way that the slidable contact plane 9 of the core part is protruded in the direction of the floppy disk plane rather than that of the slidable contact plane 10 of the slider part, by utilizing the elastic force of the floppy disk. In such way, the floppy disk receives gentle deformation in the neighborhood of a core gap position at a recording and reproducing time, and the elastic force resilient to the deformation works so as to heighten the adhesion between the surface of a floppy disk 11, and the magnetic head.

IPC: H04N19/00
Filed: 1989-04-28
Abstract: PURPOSE:To suppress the entire frequency component of a coded series by suppressing the low frequency component of an error detection code itself. CONSTITUTION:When a discrimination circuit 152 is judged as a parity represents the presence of a low frequency component based on a bit pattern detected by a bit pattern detection circuit 151, an insertion data generating circuit 153 generates a new bit pattern in l-bit to revise a bit not in use. Then the new bit pattern is used the bit not in use and the parity is calculated again and the discrimination circuit 152 is judged again whether or not the bit pattern of the new parity represents the presence of the low frequency component. Then the operation above is repeated till the parity of the pattern whose low frequency component is suppressed. Thus, the low frequency component of the code series is suppressed and excellent code transmission is attained.
