Title: Substrate holder for film formation by sputtering
Inventor: YAMADA MASAYUKI
IPC: C23C14/34
Filed: 1992-02-24
Abstract: PURPOSE:To prevent the cracking of a substrate for film formation by sputtering during film formation by using a thermal insulating material to form the contact part of the substrate holder consisting of the contact part to be imposed with the substrate for film formation by sputtering and a frame part holding the contact part. CONSTITUTION:The substrate holder for film formation by sputtering is formed by fixing a spacer S made of a fluororesin to be directly imposed with the outer edge part of the glass substrate G to the inner side of a substrate transporting tray T having a square frame shape. The tray T carrying the substrate G is moved in an arrow direction so as to intersect orthogonally with a target R in a vacuum chamber D and the target R is sputtered by a sputtering gas, by which the film is formed on the substrate G. Since the spacer S has a thermal insulating characteristic at this time, the smaller temp. difference between the outer edge part of the substrate G and the film forming surface on the inner side is only necessitated. The cracking of the substrate G is thus prevented.

Title: Driving device for focusing lens
Inventor: SUZUKI NOBORU
IPC: G02B7/28
Filed: 1987-03-26
Abstract: PURPOSE:To permit exact and smooth movement of a focusing lens to a focal position at a desired speed by correcting the change in the moving speed of the focusing lens by a change in the load on an AF motor arising from the ambient temp. at the time of photographing or the position, etc., of the camera at that time. CONSTITUTION:The focusing lens 53 is first driven by a driving signal of a predetermined duty ratio. The correction value for the deviation in the speed occurring in disturbance such as ambient temp. and difference in the position is determined in accordance with the difference between the moving speed of the focusing lens 53 during said driving and the duty ratio stored in a memory. The driving conditions for obtaining an arbitrary speed lower than said moving speed is determined in accordance with the moving speed of the focusing lens 53 during the movement, the correction value and the relations stored in the memory. The driving conditions for moving the focusing lens 53 smoothly to the focal position are thereby exactly determined regardless of the disturbance.

Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To minimize unpleasantness given to the surrounding due to noise at the time of reporting call-incoming, by stopping vibration when the difference between front/back external sound pressures is larger than a regulated value at the time of reporting call-incoming by vibration. SOLUTION: When call-incoming operation with calling is generated from an opposite party to a terminal device, a receiver 16 for controlling radio communication measures and stores the sound pressure level of outside and after then, instructs a vibration generator 15 to operate to vibrate in order to inform a user of the call-incoming. The receiver 16 measures a sound pressure level generated by vibration, compares it with a sound pressure level measured before vibrating operation and at the time of judging the difference between the sound pressure levels to be larger than a regulated value level set in advance, stops vibrating operation of the generator 15.  Thus, when noise caused by vibration is large in a situation where the terminal device is on a table, etc., the vibration for reporting call-incoming is stopped at a moment at the time of call-incoming and unpleasant feeling given to the surrounding by noise can be minimized.
