Title: Photometry unit
Inventor: NAKASE SHIGEKI
IPC: G01J1/44
Filed: 1978-11-17
Abstract: PURPOSE:To make broad the range of photometry, by correcting the output of photo emitting element, in the first mode storing the charge to the pn junction photo emitting element and the second mode discharging the charge of pn junction photo emitting element immediately before the closing of the first switch. CONSTITUTION:When the incident photo intensity to the photo emitting element 1 is comparatively small, the switch 3 is controlled to the first mode, that is, open state of between pulses with the control unit 7. In case of the first mode low in the incident light intensity, the terminal voltage of the photo emitting element 1 is the value that the incident light intensity is integrated while the open time of the first switch 2, and comparatively greater output can be obtained. When the output of the photo emitting element 1 is in excess of a set level, the control mode of the controller 7 is switched to the second control mode. The input of the amplifier 4 is related only to the intensity of light and it can change linearly without being saturated to the photo intensity.

Abstract: PURPOSE:To improve the efficiency of an input of a KANA (Japanese syllabary) character, to decrease the fatigue of a work, and also to simplify the learning by classifying and identification KANA keys on a keyboard to each line of a fifty sounds. CONSTITUTION:KANA keys on a keyboard are constituted by classifying them to eachj line of '1' line, 'ka' line, 'sa' line, ... etc. In this way, a user calls to mind to which line the KANA character belongs, first, andsubsequently, finds out a color of a KANA character key belonging to its line. Next, KANA character key to be drived is found out from in the colored KANA character key. In this case, when calling to mind a color of the KANA key peculiar to each line, it can be remembered easily since there are only 10 colors, and also a key to be derived can be found out easily from in KANA character keys of the same color, since there are only five keys. The coolored keys become a good mark to each other and the key to be derived can be found out easily.

IPC: F24D3/14
Filed: 1983-08-01
Abstract: PURPOSE:To enable to obtain the same effectiveness as the installing of another additional apparatus only with the addition of a simple radiator as a result of the adequate utilizing of a cooling fan which is used for a pump. CONSTITUTION:At the operation of a motor 20, a pump 17 is driven, a hot-water is flowed through a floor surface radiator 16, simultaneously flowed through a radiator 5. The open air is sucked from an intake port 24 of a main body 21, supplied to the motor 20 with a cooling fan 21. Thereupon, the motor 20 is cooled due to the low temperature of the open air. When a control valve 26 is moved to (c) position, an exhaust port 27 is closed and a flow passage 28 is opened, then the open air after cooling of the motor is introduced into the flow passage 28, exhausted to outdoor after warmed with a heat exchanger 5. Thus, the space heating is simultaneously performed due to both forced convection and floor surface heating, accordingly, the shortage of capability of the floor surface heating can be compensated. Subsequently, when the control valve 26 is moved to (d) position, the flow passage 28 is closed, the forced convection heating with the heat exchanger 5 is stopped, simultaneously, the air after cooling of the motor 20 is exhausted directly through the exhaust port 27. The optimum value due to both of the sufficient heating capability of the forced convection heating and the comfortableness of the floor heating can be obtained by the adjustment of the control valve 26 according to the heating space temperature.
