Title: Lens system for magnifying mirror
Inventor: RUDOBUIKU KANTSUEKU
IPC: G02B25/00
Filed: 1984-08-16
Abstract: A magnifier lens has a focal length f and a distance of at least 0.58f between the exit pupil (EXP) and the last lens (L5) vertex. This magnifier lens comprises, successively from the object-side to the eye-side, a lens, such as a meniscus lens (L1) with its concave side facing the object, a positive lens (L2) and a negative lens (L3) as well as a meniscus lens (L4) and a positive lens (L5), defining the last lens, separated by an air space (d7). The meniscus lens (L4) faces the eye with its concave side. The use of thin lenses permits a short overall length of a preferred embodiment of only 1.27f, and a sum of the lens thicknesses of 0.89f. Three large lenses (L2, L3, L4) may be made of so-called light-weight glass (SKL15 and SFL11) instead of regular glass. This results in a handy magnifier of short length and low weight with low cost of manufacture due to the small number of lens elements. A good state of correction is evidenced by a distortion of under 3 percent for a semi-field angle of 20 DEG . The magnifier lens is particularly well suited for use in optoelectronics, i.e. for observation of the image on the anode screen of an electronic tube.

Title: Image deciding device
Inventor: FUJIMOTO MASAYA
IPC: G06T7/60
Filed: 1989-06-30
Abstract: PURPOSE:To easily recognize the parts where the trimming and masking processes are carried out just by enclosing these parts with the marker lines of neutral tints by changing the discontinuous parts into the continuously parts with calculation of a virtual marker line when the distance between the discontinuous parts is smaller than a prescribed distance and detecting an area enclosed by a 2-dimensional marker line. CONSTITUTION:The 1-dimensional marker line which is detected by a 1st detection means that is embodied by a process program stored previously in a memory of a central control part 10 is stored in a program memory 12. Thus a map of the marker line is formed to an original image. Then a 2nd detection means decides the head property and the continuity of the marker line related to the plane of an original based on the mutual relationship between 1-dimensional marker lines for each scanning line stored in the memory 12. A virtual marker line is calculated when the distance between the discontinuous parts is smaller than a prescribed distance so that these discontinuous parts are changed into the continuous parts. Then an area enclosed with a 2-dimensional marker line is detected. As a result, the parts where the trimming and masking processes are carried out can be easily recognized just by enclosing these parts with the marker lines of neutral tints.

Title: High-frequency high-output hybrid integrated circuit
Inventor: WATARI YOSHIHIKO
IPC: H03F3/195
Filed: 1980-12-01
Abstract: PURPOSE:To reduce the power capacity of individual transistors and to enlarge input and output impedances, by dividing an input signal into two signals having phases opposite to each other, amplifying these divided signals, and by synthesizing them in the push-pull system. CONSTITUTION:The high frequency signal applied to an input terminal 1 is divided into two signals having phase opposite to each other by a high frequency transistor (TR)10. One signal is applied to a TR2a through a matching circuit 6a and is amplified by TRs 2a, 3a, and 4a and is applied to a high frequency transformer 11. Similarly, the other is amplified by TRs 2b, 3b, and 4b and is applied to the high frequency transformer 11. The high frequency transformer 11 synthesizes two amplified signals having phases opposite to each other and outputs the synthesized signal from an output terminal 5. At this time, since it is sufficient if power capacities of output TRs 4a and 4b are half, the output impedance becomes twice.

Filed: 1984-08-16
Abstract: PURPOSE:To allow an easy selection of a condition in which a full circulation function is to be made or a condition in which the air cleaning function is desired by providing two separate air intake passages of a passage which is connected to the room through a filter and a passage which is directly connected to the room without filter. CONSTITUTION:When a damper 9 is closed, the intake airflow is led into a casing 4 after being cleaned by passing from an intake grill 7 through a dust filter 5 and a deodorant filter 6, and is released into the room from an outlet grill 8. In this instance, as the circulation flow all passes through the dust filter 5 and the deodorant filter 6, a high air cleaning function is obtained. On the other hand, when the damper 9 is opened, an air intake passage that does not include the filters 5, 6 is formed, and so, the airflow rate is increased to highten the circulation function. Therefore, by operating a puall switch 10, an easy selection can be made between the high air cleaning function and the high circulation function.
