Filed: 1984-05-18
Abstract: PURPOSE:To economize the time required for designing an optical system and to economize the time and cost required for development of an optical head by adding a beam splitter to a condenser lens and diaphragm lens, considering the optical system constituted thereof as one object to be designed and correcting an aberration over the entire part of the optical system. CONSTITUTION:The wave surface 10 of the light which is emitted from a semiconductor laser 1 and is past the 1st group optical system constituted of the condenser lens 9 consisting of a single lens having positive power and the beam splitter 3 contains the wave front aberration symmetrical with the optical axis. However, the wave surface can be approximated to the ideal plane wave by designing adequately the optical system. The diaphragm lens 4 which is the 2nd group optical system is designed to form a satisfactory spherical wave 11 after correcting the aberration remaining slightly in the surface 10 and making the light incident on a transparent parallel plate 5 for protecting the recording surface. Said lens forms the light spot of a satisfactory microdiameter on the recording surface 6. The diaphragm lens satisfying such performance is realized by a combination lens of three pieces. The number of the lenses required for the entire part of the optical head is made four pieces and is reduced by approximately half as compared to the conventional head.

Filed: 1984-05-21
Abstract: PURPOSE:To form a uniform coated film, by providing with variable exhausting means which control quantity to be exhausted according to a detected output developed from means for measuring a flow rate of exhausted gas. CONSTITUTION:Inside the cup 16 which consists of an upper cup 16a and a lower cup 16b, partitions 22, 24 are formed, with their lower ends extended to the lower cup 16b and with their upper ends extended to a wafer 2. The partition 22 can reduce a volume in the space 24 to be exhausted, so that air flow having a sufficient flow rate can be produced over the wafer 2 surface even if the space 24 is exhausted by an evacuating system having a limited ability. Therefore, since a flow rate of air flowing across the wafer 2 surface can be selected over a wide range with the partition 22 being formed inside the cup 16, a rotating rate of the turn table and a flow rate of air can be controlled over a properly wide range, thus to provide a coated film with a required thickness.

Title: Switch and input device using switch
Inventor: TANIGUCHI MINORU
IPC: H01H9/18
Filed: 1990-04-17
Abstract: PURPOSE:To simplify discrimination of first terminal, so as to enable correct connection to an input device, and to avoid malfunction of device by electrostatic discharge or internal element destruction, by indicating a marking on the first terminal of a switch. CONSTITUTION:A marking 7 to discriminate the first terminal 5 of a switch 8, is indicated by paint, etc., on casing 4 near a terminal 5. In an input device using the switch 8, internal element 9 of the input device is connected to second terminal 6 of the switch and the first terminal 5 is connected to the ground side of the device. Therefore, on the switch, the electrostatic discharge applied to an operating button 1, is transmitted to the first terminal 5 via the first contact 3a, but not to the second terminal 6. In the input device because the first terminal 5 is connected to ground side, the electrostatic discharge is transmitted to the ground side through the first terminal 5 and hardly transmitted to internal element 9, then malfunction of the input device or breakdown of the internal element can be prevented.
