Title: Fresnel lens
Inventor: SATO MAKOTO
IPC: G02B3/08
Filed: 1994-09-02
Abstract: PURPOSE: To provide a Fresnel lens which decreases stray light, prevents the loss of light and can make the entire part bright. CONSTITUTION: In the Fresnel lens having plano-convex positive power, of which light incident face is formed as plane 1, and of which prism lens part 2 having a lens face 4 and non-lens part 5 is formed on the light exiting face, the angle of inclination of the non-lens face 5 of the prism lens part 2 is set within a range of the angle formed by the direction of the incident main rays on the inside of the lens and the direction of the main rays emitted outside the lens.  Then, the margins of the angle θ1 formed by the incident rays on the inside of the lens with the non-lens faces 5 and the angle θ2 formed by the rays emitted outside the lens are generated and, therefore, even if the rays from the points slightly deviated from the optical axis arrive at the non-lens faces 5, the rays are emitted nearly along the optical axis and the stray light by the non-lens faces 5 is decreased. The loss of the light is thereby prevented and the entire part is made bright.

Title: Magnetic bubble transfer route
Inventor: SUZUKI MAKOTO
IPC: G11C19/08
Filed: 1984-11-09
Abstract: PURPOSE:To realize a transfer margin same as in a linear part, by providing minute gaps to which ions is charged in at the inner corner where the magnetic bubble takes 180 deg. turn. CONSTITUTION:When the magnetization of a layer to be charged with ions proceeds towards the ion charged area, and the magnetization has a difficulty in heading towards that direction by its antimagnetic field. And therefore, at the inner corner the rotation of the magnetization of the ion charged layer becomes difficult, and the transfer margin is narrowed. To avoid this, it is necessary to reduce the diamagnetic field, i.e. the magnetic poles appearing at the ion charged border. One method for this is to provide a gap which consists of the ion charged area at the inner corner part. In case this gap is small, the magnetic bubble hardly go through the gaps, and operates as the inner corner. That is, by this inner corner, the transportation direction of the magnetic bubble takes 180 deg. turn.

Title: Stereo demodulator
Inventor: NAKAJIMA MITSUHIRO
IPC: H03D3/00
Filed: 1991-09-17
Abstract: PURPOSE:To eliminate the DC component and to prevent the misdecision of the synchronizing detection by using the output signal of an EXOR circuit to control a switch circuit which switches a route where the pilot signal of an input circuit is directly inputted and a route where the pilot signal is inputted via an amplifier. CONSTITUTION:The pilot signal received from an input terminal 64 is switched by a switch circuit 21 between a route where the pilot signal is directly inputted and a route where the pilot signal is inputted via an amplifier 20. Then the pilot signal is inputted to an analog multiplier consisting of the transistors 12-17. The circuit 21 is switched toward the amplifier 20 when the switch control signal, i.e., the output of an EXOR circuit received from an input terminal 65 is kept at an L level. Therefore the plus and minus DC components are equal to each other in regard of the tertiary harmonic signal outputted from an output terminal 66. Thus the DC component is eliminated out of the terminal 66 and the misdecision of the synchronizing detection can be prevented.
