Title: Interference length measuring instrument
Inventor: NISHIKAWA NAOYUKI
IPC: G01B9/02
Filed: 1993-10-26
Abstract: PURPOSE:To provide an interference length measuring instrument where no measurement error occurs even if an optical path difference changes while the wavelength of laser beams changes. CONSTITUTION:A pair of laser light sources 1a and 1b for transmitting laser beams with different wavelengths are provided. Also, the wavelength of laser beams is swept at the laser light sources 1a and lb. The laser beams from the laser light sources 1a and 1b are synthesized so that they pass the same light path by a beam splitter 3a and are split into reference light and object light. The object light is applied to an object S to be measured and the reference light reflected by a reference mirror 6 interferes with the rear scattered light at the object S to be measured on a beam splitter 4a. A dichloic mirror 5a separates interference intensity for each wavelength and detects the interference intensity according to corresponding eight reception elements 2a and 2b. An operation processing part 24 obtains the distance to the object S to be measured based on the phase error of beat signals which are obtained by both light reception elements 2a and 2b.

Abstract: PROBLEM TO BE SOLVED: To make a system camera have an imprinting setting rotation for preventing a meaningless imprinting setting from going round even if setting it when an AE finder is not loaded, as for the system camera capable of recording imprinting data. SOLUTION: The imprinting setting of regarding photographic data obtained by the AE finder as the imprinting data is registered only at setting steps 2 and 3. When a button is depressed, data counter corresponding to the imprinting setting selected at the present is increased by one as an increment (#1). When the AE finder is not loaded, the path is shifted to #3a, and when the counted value is two, the path is shifted to #4a, then, shifted to #5 after making the count zero. When the counted value is not two, the path is shifted from #3a to #5 directly. On the other hand, when the AE finder is loaded, the path is shifted to #3b and when the counted value is four, the path is shifted to #4b, and then, shifted to #5 after making the count zero. When the counted value is not four, the path is shifted from #3b to #5 directly.  The data setting is executed in accordance with the data count at #5.

CONSTITUTION: In such a state that ink is directly supplied to an ink jet printing head 164 from a main ink reservoir 158 through a main ink feed capillary 156, negative back pressure is kept by the surface tension of air bubble formation and, when the temp. and pressure in a main ink reservoir housing 140 exceed certain levels, the ink passes through a balanced capillary 148 by capillary action to be drawn out into an auxiliary ink reservoir 150. When the temp. in the housing 140 begins to return to a usual room temp. operation range, the pressure in the main ink reservoir is reduced and the ink is returned to the main ink reservoir 158 through the balanced capillary 148. During this period, a vent pipe 154 takes in and out air between the auxiliary ink reservoir 150 and the open air and this pressure regulation continues until the ink of an ink jet pen is perfectly exhausted.
