Title: Satellite reception antenna system
Inventor: YAMAMOTO HIROHIKO
IPC: H01Q19/17
Filed: 1985-08-30
Abstract: PURPOSE:To use a single reflection mirror in common for the reception from two kinds of satellites by placing a primary radiator used for higher frequency waves among radio waves from the two kinds of the satellites to a focus of the reflection mirror and placing other primary radiator to a deviation point. CONSTITUTION:The reflection mirror 3 is positioned so that a transmission wave from the 1st satellite 1 is in parallel with an axis 3b of the reflection mirror 3, the primary radiator 10 for the satellite 1 is arranged to a focus 3b of the reflection mirror 3 and the 1st satellite reception antenna is set to obtain the maximum sensitivity. The primary radiator 20 receiving the transmission wave from the 2nd satellite 2 is arranged at a position deviated from a focus so as to be made coincident with the reflected wave from the reflection mirror. Since the radiator is fed with a deviation, the deterioration of the gain is caused, but it is negligible because the frequency of the irradiated wave of the satellite 2 is low in the frequency in comparison with that of the satellite 1 and the gain reduction is remarkably low. Thus, the single reflection mirror can receive the radio waves from the two satellites having a different transmission frequency.

Title: Optical character reader
Inventor: KURAKAKE MASAHIRO
IPC: G06K9/38
Filed: 1990-07-20
Abstract: PURPOSE:To satisfactorily read either a normal character or an inverted character as well by applying the output signal of a binarizing means to an identifying means when a deciding means detects the existence of a character and applying the output signal of an inverted binarizing means to the identifying means when an inverted deciding means detects the existence of a character, respectively. CONSTITUTION:For example, when the existence of the normal character formed in black on a white background is detected by the decision of a deciding means 11P, a switching means 10 applies a binary signal from a binarizing means 7P to a character identifying means 15. On the other hand, when the existence of the inverted character inverting the size relation of brightness by inverting the black/white of the normal character is detected by the decision of an inverted deciding means 11N, for example, the switching means 10 applies a binary signal from an inverted binarizing means 7N to the identifying means 15. Therefore, a binary picture expressed by the binary signal applied to the identifying means 15 is made corresponding to the normal picture even when a character formed on a reading face is either normal or inverted. Thus, the both characters can be identified by the identifying means 15 which can identify only the normal character.

A film 8 for exposure is placed on a glass plate 11 in contact, liquid photosensitive resin 10 is applied over the film, and a reverse plate 9 is pressed against it flatly to secure constant thickness size of the photosensitive resin. Light from a light source 12 passes through the film 8 for exposure to illuminate the photosensitive resin 10, so that an irradiated part cures and an unirradiated part is still liquid. The photosensitive resin 10 is taken out together with the reverse plate 9 after the resin cures as specified, and the uncured part is washed away to obtain a seal having an uneven surface.
