Title: Manufacture of thin-film transistor
Inventor: SASANO AKIRA
IPC: H01L21/336
Filed: 1984-05-09
Abstract: PURPOSE:To form an overlap in a self-alignment manner by shaping a mask layer between a photo-resist and a gate electrode and utilizing the over-etching of the mask layer. CONSTITUTION:A gate electrode pattern 2 in Cr is formed on a glass substrate 1, a gate insulating film 3 in Si3N4, etc. is shaped on the pattern 2, a-Si 4 is deposited on the insulating film 3, and an organic resin (polyglycidyl methacrylate) 8 is applied and cured as a mask layer. A positive type photo-resist 5 is applied, and ultraviolet rays are projected from the back of the glass substrate to expose the photo-resist. The photo-resist 5 is removed, thus obtaining a pattern 8 in polyglycidyl methacrylate having width narrower than gate width by approximately 4mum (2mum on one side). Cr and Al are evaporated, and polyglycidyl methacrylate is removed, thus forming a source 6 and a drain electrode 7 overlapping at every 2mum.

Title: Remote controller
Inventor: KITAMURA TETSUO
IPC: E06B9/68
Filed: 1997-04-09
Abstract: PROBLEM TO BE SOLVED: To simply delete an undesired registration signal by providing a control means for the controller which deletes a registration signal corresponding to a transmitter identification signal other than a transmitter identification signal of a new transmitter. SOLUTION: At application of power by the operation of a power switch 11, the controller is set in the delete mode where an unnecessary registration signal set to a controller body is able to be deleted. Furthermore, whether or not delete of an unnecessary registration signal stored in an EEPROM 13 is reserved is discriminated. When having already been reserved, all unnecessary registration signals except a new registration signal among the stored registration signals are deleted from the EEPROM 13. When delete of the unnecessary registration signal is not reserved, the controller is set in the delete reservation mode where the delete of the unnecessary registration signal is able to be reserved and a timer 14 starts time count for the delete reservation processing.  If it is discriminated that a remote control signal from a new transmitter is sent consecutively for 30 seconds within 5 minutes, the delete of all unnecessary registration signals except a new registration signal among the stored registration signals set to the controller body are reserved.

Abstract: PURPOSE:To obtain the optimum gain of a focus servo system and to reduce equipment noises by providing a position detecting mechanism for an objective lens, and varying the gain of the focus servo system according to the detected amount of surface undulation of a disk. CONSTITUTION:A capacity plate 14 is so constituted as to vary in capacity C linearly with unipolarity over the entire movement range of the objective lens 5, so the variation in capacity C is detected to know the position of the objective lens 5. The position of this objective lens 5 is converted by an oscillation circuit 15 into a frequency, which is converted into a DC voltage by an FM detecting circuit 17 after noises are removed through a band-pass filter 16. Some of the output of the FM detecting circuit 17 which contains position information on this objective lens 5 is inputted to a low-pass filter 18 to remove an abrupt variation component of the objective lens due to surface undulation, thereby detecting the mean position of the objective lens 5 determined individually by the thickness of the disk. A differential amplifier 19 eliminates the difference to detect the amount of displacement of the objective lens 5.
