A shift control system for an automatic transmission, comprising a shift unit for selecting by manipulating a shift lever an automatic shift mode, in which a gear stage is determined on the basis of a running state of a vehicle, and a manual shift mode in which a gear state is determined from an output signal based on the manipulation. The shift unit has a drive range capable of setting a plurality of forward gear stages and a plurality of range positions arrayed and includes: a first shift path for guiding the shift lever into the range positions; a second shift path intersecting the first shift path for guiding the shift lever; two third shift paths formed at the two end portions of the second shift path, the third shift paths having at their individual end portions gear stage positions for indicating the forward gear stages in the automatic shift mode and for guiding the shift lever; and a manual shift instructor for outputting a signal instructing a gear stage corresponding to the gear stage position when the shift lever is moved to the gear stage position. The shift control system comprises a gear stage setter for setting the gear stage which is instructed by the output signal of the manual shift instructor.

An electronic flash device fires one or a pair of flash tubes sequentially for continuous shooting photography with a motor driven photographic camera, for substantially continuous illumination or for sequential illuminations at intervals, as well as fire the flash tube a single time for one shot photography. The flash device is provided with a main capacitor and an auxiliary capacitor which selectively energize the flash tube or tubes. The auxiliary capacitor is charged by the main capacitor and discharged to energize the flash tube for a small amount of flash light and shorttime restoration of the flash firing circuit. When a pair of flash tubes are employed, they are alternatively actuated for the sequential firing and one of them is actuated for the single time firing. The pair of flash tubes are coupled with each other through a commutation capacitor and switch elements for quick repetition of their firings.

A color measuring apparatus for measuring the color of a sample has a light source measuring section for detecting color temperature of light coming from a light source without passing through or being reflected by the sample. Relationship between a plurality of color temperatures and a plurality of emission time periods of the light source is stored in a memory. A microcomputer compares each of detected color temperatures with a predetermined value and determines a certain time period on the basis of both the relationship stored in the memory and a comparison result. A lighting circuit energizes the light source during the time period determined by the computer so that the light source keeps lighting the sample. A sample measuring section detects light coming from the sample and the microcomputer measures a color of the sample.

A light sensor comprises optical filters, an interference filter and a photoelectric converting element which receives and photoelectrically converts light which has passed through the optical filters and the interference filter. An incident angle of the incident light on the interference filter can be changed so as to realize a desirable spectral sensitivity in a combination of the optical filters, the interference filter and the photoelectric converting element. The incident angle can be changed by a mounting structure that can rotate about an optical axis.

An enlarger for copying a film is provided having two modes of operation. A first mode of operation permits preliminary adjustment of the focus of the lens system while the second mode of operation permits an actual exposure, the first mode of operation being inhibited during the actual exposure of the film in the second mode.

An enlarger for use in photography capable of printing a color copy from a color original film includes a light source for generating a plurality of primary colors and a microcomputer for controlling the light source. The microcomputer has various functions which are: for providing a plurality of exposure data corresponding to a plurality of primary colors; for designating at least one of the primary colors; for altering the exposure data corresponding to the designated primary color; for displaying an information relating to the exposure data to be altered; for indicating the direction of change in tone of the color copy caused by altering the exposure data; for selecting the type of the original film; and for controlling the relation between the direction of change in tone of the color copy as indicated and the direction of change in the exposure data as displayed in response to the selected type of original film.
摘要:
A spectrophotometer utilizes a band-pass filter array for splitting incident light into a plurality of light components of different wavelengths, a plurality of silicon photodiodes for receiving the respective light components, and a memory for storing spectral sensitivity information. The spectral sensitivity information is obtained by integrating the spectral sensitivities of spectrodetectors relative to each sectionalized wavelength regions sectionally generated from a measurement wavelength region. Each of the spectrodetectors include a band-pass filter array and a silicon photodiode in combination. A central processing unit calculates simultaneous equations representing the relation between the output from each of the silicon photodiodes, the spectral sensitivity information stored in memory and the light intensity of the sectionalized wavelength region, to obtain the light intensity.
