Title: Contour extraction circuit
Inventor: MATSUNAWA MASAHIKO
IPC: H04N1/387
Filed: 1989-02-23
Abstract: PURPOSE:To prevent void occurred in a conventional device by extracting a prescribed number of picture elements before and after the leading and trailing of a picture signal relating to the main scanning direction and the subscanning direction equally so as to obtain a contour signal. CONSTITUTION:A contour internal signal is retarded by 2 picture elements respectively in delay elements 503, 504 comprising a shift register and 3 retarded picture data are supplied to exclusive OR circuits 511, 512 being components of an edge detection circuit 510 in the main scanning direction and an edge signal is generated.

Title: Total heat exchanger
Inventor: YAMADA KENKOU
IPC: F28F19/04
Filed: 1978-04-19
Abstract: PURPOSE:To adapt hot fluid of about 80 degrees C. for the continuous use on one side by using aromatic heat-resisting polymer film or the same containing metal salt for the heat exchanging bodies. CONSTITUTION:Films about 5-500 micons thick are shaped from aromatic polyamide or polyimide, or aromatic heat resisting polymer given by adding deliquescent metal salt such as zinc chloride to the above. These aromatic heat-resisting polymer films are laminated as actual or latent heat exchanging bodies for forming a heat exchanger. In this construction, actual and latent heat can be exchanged efficiently, and the apparatus can be applied for a continuous use of long duration even if one of the two fluid to exchange heat is of high temperature above about 80 degrees C. Since the films are highly resisting against chemicals, they can be applied for areas where resistivity against chemicals is necessary or for very low temperature.

Title: Eyepiece, finder optical system and optical equipment having the same
Inventor: HAYAKAWA SHINGO
IPC: G02B25/00
Filed: 1998-02-26
Abstract: PROBLEM TO BE SOLVED: To effectively eliminate a harmful light performing an internal-surface reflection at the side edge surface (outside surface) of an ocular optical system without making the system larger by providing a light shielding groove at the side edge surface while making an eyepiece in the facade shape corresponding to a visual shape. SOLUTION: A harmful light which never reaches the pupil of an observer is made incident on the pupil by the internal-surface reflection at the side edge surface of a second lens to lower the visibility of a finder. For the purpose, the eyepiece has the constitution provided with a light shielding groove at the side edge surface of the lens to eliminate the harmful light satisfactorily. The lens has a facade shape analogous to a light beam effective area so as to be miniaturized as much as possible like it is seen in the figure (c). Since the light beam effective area is decided according to the shape of a visual field, the facade shape of the lens is decided according to the shape of the visual field.  Since there is a possibility that one part of the harmful light reflected at the light shielding groove of the lens is left in the lens even after the light shielding groove is formed in this manner, a black coating is applied on the side edge surface together with the light shielding groove.
