Filed: 1989-11-21
Abstract: PURPOSE:To improve dimensional precision and yield by a method wherein a mask is formed by patterning a mask material film composed of inorganic material by using photolithography technique. CONSTITUTION:After a polysilicon film 2 is formed on a semiconductor substrate 1, a silicon nitride film 3a of 1000-2000Angstrom  in thickness is arranged on the film 2. A resist film 4 is formed in a desired pattern on the silicon nitride film 3a.

Abstract: PURPOSE:To prevent plastic deformation of locking spring parts and to prevent bending of a terminal metal fitting to prevent mutual interference between adjacent locking spring parts by providing a driver stopper in the locus of movement of a driver and providing rigidity reinforcing means in bend base parts of the terminal metal fitting and locking spring parts. CONSTITUTION:When an electric wire is inserted between a terminal metal fitting 7 and a locking spring part 13, the locking spring part 13 presses the electric wire to the terminal metal fitting 7 while deforming. At this time, the terminal metal fitting 7 tries to bend but is prevented from bending by a rigidity reinforcing means 8. The deforming force of one locking spring part 13 tends to be transferred to the other locking spring 13 via a bottom part 12, but the deforming force is prevented from being transmitted through a bottom part by a rigidity reinforcing means 20 provided in a bend base part 15. When the driver is inserted from a driver insertion hole 30 to push up the front end of the locking spring part 13 at the time of pulling out the electric wire, the locking spring part 13 is not excessively pushed neither plastically deformed because the driver comes into contact with the driver stopper and stops going.

IPC: B41J2/18
Filed: 1998-10-26
Abstract: PROBLEM TO BE SOLVED: To prevent a recording image from being disturbed by ending the operation of a carrying means after ending maintenance when a recording head is to be maintained by a maintenance means during recording operation. SOLUTION: Ink is ejected from a recording head simultaneously upon starting scanning operation of a carriage 2, and an image is formed on a recording medium, i.e., a recording sheet 4. When maintenance of the head is required, the carriage 2 back scans to a predetermined position while stopping a carrying means, i.e., a sheet feed roller 7 and then the head is maintained followed and the sheet is fed by a specified amount. According to the arrangement, position of the recording sheet 4 is corrected even if it is shifted due to vibration during maintenance operation. Furthermore, the image is not disturbed even after maintenance of the head during recording operation because the vibration mode of the entire printer immediate before recording operation is same as that during normal recording operation. Consequently, high image quality recording is realized.

Therefore, the feedback loop is made to be a steady state at the state that the output of the LPF 4 is zero, that means, the phase delay quantity (or the lead quantity) alpha is 90 deg.. Then, when the voltage or the current controlled type oscillating circuit 5 or 6 is set so as to be the oscillation frequency obtained by the voltage value (the current value) of the control terminal of the circuit 3 in the steady state, the oscillation frequency can be kept constant. Thus, the oscillating circuit can be constituted with no adjusting part.
