Title: Optical thin film and refelction preventive article
Inventor: OKA KOICHIRO
IPC: G02B1/14
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To obtain the reflection preventive optical thin film easy in manufacture and superior in abrasion and scratching resistance by using a specified compound subjected to hardening treatment. SOLUTION: The reflection preventive optical thin film is made of the hardened compound represented by the formula in which Rf is an alkylene group containing F atoms; (a) is 0 or 1; and (b) is 0, 1, 2, or 3. Rf may be a straight car branched alkylene group, and a part or all of the H atoms are substituted by the F atoms. The preferable alkylene group to be used is a straight chain one from the point of easiness of manufacture and all the H atoms are, preferably, substituted by the F atoms in the case of perfluoroalkylene in order to obtain the optical thin film as low as possible in the reflective index. It is favorable from the point of the easiness of manufacture that (a) is 0 or 1, and if (b) exceeds 3, the hardness of the optical thin film tends to become insufficient.

Title: Scanning electron microscope
Inventor: MORIWAKI HIRONOBU
IPC: H01J37/28
Filed: 1981-05-28
Abstract: PURPOSE:To enable the physical change with a long cycle of a sample to be observed by providing a means of switching the sample into a different physical state synchronously with the horizontal scanning of electron rays irradiating the sample, and providing a means of displaying plural sample-images each corresponding to a different physical state of the sample. CONSTITUTION:A scanning-signal generating circuit 9 produces a scanning signal with a frequency twice the frequency of the output of a scanning-signal generating circuit 4 according to the output of the circuit 4. Since the frequency of a coil 11 is several hundred times that of the horizontal scanning signal, the two- dimensional scannings of both a sample surface and a Braun-tube picture surface are carried out. When a coil 16 is supplied with the output current of a rectangular-wave generating circuit 17, which produces a current with rectangular waves indicated in the figure 5 according to the output of a generator 3, a breakable sample such as silicon steel undergoes an a.c. breakdown. Scanning images displayed on the right and the left sides of the Braun-tube picture surface, respectively, correspond to the states of the breakable sample broken in (+) direction and (-) direction. As a result, two different images of the sample placed under different conditions can be observed at the same time.

IPC: B24B37/30
Filed: 1979-06-30
Abstract: PURPOSE:To obtain a substrate having highly excellent flatness by a method wherein a mirror finish is effected on a convex side of a warpage produced by lapping with diamond paste to cancel a concaved deformation and the convexed warpage each other. CONSTITUTION:A load 5 is applied on a ceramic or crystallized substrate 4, both sides of which are roughly ground, through a ring spacer 6 corresponding to the substrate 4 and a lapping work is effected thereon. In this case, the substrate 4 produces a warpage so that a lapped surface 4a thereof becomes convex in accordance with a difference of stresses between the same in a loaded portion and a nonloaded portion due to the ring spacer 6. Next, a mirror finish is effected with diamond paste on the convex surface 4a of the base plate 4 already produced the warpage to cancel a concaved deformed portion and the convex warpage, and thus, the substrate 4 having highly excellent flatness may be obtained.

Filed: 1994-03-15
Abstract: PURPOSE:To provide good dust-proof structure and high operability by arranging a rubber sheet, a rubber pillar or the like in a multi-way switch or a position specifying device having a circuit substrate to mount a switch or a displacement detection mechanism. CONSTITUTION:A key 1 is secured with rubber pillars 13 erected on a rubber sheet 10 and operable with a minimum force in a direction horizontal to the flat surface of a substrate 20. When the key 1 is operated horizontally, one of four projections 2 thereof pushes the corresponding projection 11 of the sheet 10 externally from a center. A skirt 12 has a low profile along a center direction and the lateral shift of the projection 11 is restricted, thereby being tilted about the inner lower section thereof as a support point. Also, the electrode 16 of an electrode sheet 15 on the reverse side of the projection 11 is pushed down and a contact 21 and the electrode 16 come in contact with each other, thereby closing a switch. In the case of a position specifying device, a resistance member is used for the electrode 16, and the area of contact with the contact 21 or pressure changes. The switch is, therefore, is used as an analog sensor. Also, approximately complete dust-proof structure can be provided, due to the use of the rubber sheet 10.
