Title: Electronic blackboard system
Inventor: HASHIMOTO TAKESHI
IPC: H04N7/15
Filed: 1984-07-31
Abstract: PURPOSE:To enable the attendants of a conference, etc. to omit the job for transcribing the contents written on a blackboard and also to display the charts, tables, etc. at all times by means of the rear side (white board) of the blackboard, by providing a white board to the rear side of an electronic blackboard which records patterns, characters, etc. written on a writing medium made of a rolled sheet. CONSTITUTION:When an electronic blackboard system is used, a user writes patterns, characters, etc. on a writing medium 1 and then pushes a key on an operation panel 15 for recording those patterns, characters, etc. Thus an optical reading means 9 reads patterns, characters, etc. while the medium 1 is taken up to a holding mans 2. These read patterns, characters, etc. are recorded on a recording form 13 in the form of digital signals by a recording means 12 via an amplifier 10 and an A/D conversion means 11. A white board 18 on the rear side of the blackboard can be used by turning a main body part 14 by 180 deg. centering on a post 17. Thus the patterns, characters, etc. can be written on the board 18.

Abstract: PURPOSE:To obviate the generation of axial misalignment and to allow the exact butting of the front end faces of respective pairs of fibers by fixing the butt surfaces of the fibers inserted into the holes of a capillary with a 1st resin and fixing a cap body and a substrate with a 2nd resin layer. CONSTITUTION:A UV curing resin having nearly the same refractive index as the refractive index of the cores of the fibers 14a, 14b is injected into grooves 8 of the capillary 2. The front ends of the fibers 14a, 14b are then respectively separately inserted into the holes 9a, 9b of the capillary 2 and the front end faces are butted against each other. The coated tape optical fibers 13a, 13b are then fixed by, for example, fixing jigs, etc., not shown in Fig. The capillary 2 is irradiated with UV rays to cure the UV curing resin, by which the 1st UV curing resin layer is formed. The UV curing resin 19 is injected over the entire front surface of the substrate 1 and the cap body 10 is put on the substrate 1. The front surface of the substrate 1 is irradiated with the UV rays through the cap body 10 to cure the UV curing resin 19, by which the 2nd UV curing resin layer is formed. Such connecting device is small in connection loss, is stable in performance and is excellent in environmental resistance.

Abstract: PROBLEM TO BE SOLVED: To improve the reliability of a product and reduce the manufacturing cost on the product by integrally providing a coin-type battery holder with a lock mechanism. SOLUTION: In a housing structure for a coin-type battery holder that is used for housing a battery holder 16 in a battery housing part of a casing 15 of a small electronic equipment, this structure having a lock knob 31 exposed to the outside comprises a crank strip 30 formed in the shape of a cantilever, an engaging projecting part 34 protrusively formed on the crank strip 30, a tapered strip 32 protrusively formed on the outside end of the lock knob, an engaging recessed part 21 that is formed in the battery housing part and is interfittable with the engaging projecting part 34, and a stepped part 23 having a tapered surface 36 which is engageable with the tapered strip 32.  In this case, since the engagement of the battery holder 16 with the battery housing part is performed by interfitting the engaging projecting part 34 with the engaging recessed part 21, the engaging state is not released, even if a force in the ejecting direction is imposed on the battery holder 16. Furthermore, when the engaging state is released, the tapered strip can be slided on the stepped part, so that the battery holder 16 can be taken out smoothly.

IPC: G01B7/28
Filed: 1986-07-14
Abstract: PURPOSE:To obtain a method which is especially convenient for evaluating patterns of a number of samples by a method wherein, after an object pattern to be evaluated is formed, a stripe pattern is formed with material containing tungsten silicide by depressurized vapor deposition and the electric resistance of the stripe pattern is measured to evaluate the cross-sectional shape of the sample indirectly. CONSTITUTION:A fine object pattern 2 to be evaluated is formed on a substrate 1 and a WSi2 (tungsten silicide) film 3 is deposited by depressurized chemical vapor deposition so as to make itself cross the pattern 2 at least one time. Then resist is applied to the WSi2 film 3 and the WSi2 film 3 is partially removed with the resist as a mask to form a stripe pattern 31 with the width of about l-3mum. Therefore, an oxide film 4 is uniformly formed on the top surface of the pattern and on the surface of the substrate 1 and, at step parts, the oxide film 4 is so formed as to cut into the inside. With this constitution, if a resistance between both the ends A and A' of the WSi2 stripe pattern 31 crossing the pattern 2 whose cross-sectional shape is to be formed is measured by a tester or the like, the cross-sectional shape of the foundation of the object pattern 2 to be evaluated can be evaluated indirectly.
