Title: Light guide plate and surface light source device
Inventor: FUNAMOTO AKIHIRO
IPC: F21V8/00
Filed: 1998-07-15
Abstract: PROBLEM TO BE SOLVED: To lessen influence of a displacement of a point light source to a light incoming part, by providing plural small holes or grooves ranging to an external part in the vicinity of the light incoming part, and by diffusing and reflecting the introduced light inward in the boundary of the small hole or groove. SOLUTION: Longitudinal stripes 30 are provided on a light incoming part 24 facing a point light source and areas on its both sides. Thereby, light (f) incoming into a light guide plate 22 from the light incoming part 24 and its periphery is directed toward the corner part of the photo-conductive plate 22 by the light incoming part 24, and is also diffused on a parallel plane to a light outgoing emission surface by the longitudinal stripes 30. The longitudinal stripes 30 provided on both sides of the light incoming part 24 also introduce light from the point light source into the light guide plate 22 without being totally reflected. Accordingly, light utilization efficiency can be enhanced by a surface light source device using this type of light guide plate 22.  In addition, luminance distribution on the light outgoing emission surface can be uniformed, and particularly the corner of the light guide plate 22 is prevented from darkening.

Abstract: PURPOSE:To drive a lens speedily and to set plural distances by comparing a preset or stored distance value with the output of a lens position detecting means and driving a lens moving motor. CONSTITUTION:The output voltage of a lens position detector 85 consisting of a permanent magnet and a magnetoelectric converting element is compared 83 with the output voltage of a variable resistance 81 for preset distance setting, and transistors (TR) 91-94 forming a driving circuit 90 are turned on and off on the basis of the comparison output. Consequently, the motor 95 is rotated in such a direction that deviation is eliminated and stops where the deviation is zero. Then, when a release switch 101 is closed for shutter releasing, TRs 105 and 106 turn on and the driving circuit 90 is turned off to take a photography in a photographic lens still state.

Abstract: PURPOSE: To reduce power loss in a transparent electrode by collecting charges generated at the transparent electrode side to a metal film at the rear surface through a through hole provided at a metal substrate. CONSTITUTION: An amorphous semiconductor thin film 22 and a transparent conductive film 23 are stacked on the main surface at one surface of a metal substrate 21 providing through holes 26 with a constant interval. A metal substrate 21 is used as a first electrode and a transparent electrode as a second electrode to fort a cell.

IPC: B41J2/38
Filed: 1984-09-27
Abstract: PURPOSE:To maintain uniformity of density of printed dots and enhance printing quality, by preheating a heating element not supplied with an electric current for printing, at the time of printing. CONSTITUTION:At the start of printing, each of the heating element is in a thermal equibrium state. The heating element used for printing is supplied with a driving pulse with a width t1 to perform printing, while the heating element 1a not used for printing at this time is supplied with a printing pulse with a width t3 to heat the element to a temperature Ta, which is set to be not higher than the transferring temperature of a printing ribbon. The temperature of the heating element at the next printing period is either Ta (where the element has been used in the preceding- time printing) or Tb (where the element has not been used in the preceding-time printing). Accordingly, in the next printing, the heating element is driven with a printing pulse width t2 where the temperature thereof is Ta or is driven with a printing pulse width (t2+t4) where the temperature thereof is Tb, whereby a suitable dot can be printed. When not printing, the heating element is supplied with a printing pulse with a width t4 to heat the element to the temperature Ta, only when the temperature of the element is Tb. By carrying out the same treatment in the subsequent printing operations, it is made possible to print suitably.
