Title: Waste ink container and ink jet recorder
Inventor: SUENAGA KOJI
IPC: B41J2/175
Filed: 1999-12-02
Abstract: PROBLEM TO BE SOLVED: To house a larger volume of waste ink per unit volume while preventing leakage of waste ink due to variation of attitude. SOLUTION: A double tube member 46 is placed on the upper plate 36A of a container body 36. The double tube member 46 comprises an inner tube for passing waste ink into the container body 36, and an outer tube for interconnecting the inside and outside of the container body wherein the inner end parts 48A, 50A thereof are located at the center 60 of inner volume of the container body 36. Even if the attitude of the container body 36 is varied while containing waste ink by less than half of the inner volume thereof, waste ink in the container body 36 does not leak because the inner end parts 48A, 50A are located above the liquid level of waste ink. Since waste ink is housed directly in the container body 36, a larger volume of waste ink can be housed per unit volume.

Abstract: PURPOSE:To eliminate dislocation of a designated stop position of a wiper by stopping a motor after turning an AS switch fully once in case the AS switch is connected with IG when a wiper switch and an intermediate wiper switch is turned off by a driver's decision. CONSTITUTION:When an output of an intermediate control block 15 is H, if a driver turns a switch off while a motor 11 is turning, an output of a NAND gate 23 in FF 60 is H and an output of an AS(autostop) switch 10 is H and an output of the NAND gate 24 is L and a wiper control relay 18 holds a closed condition. Then, if the AS switch 10 varies to L, the relay 18 is opened after delay time passes in a delay circuit 50 but at that time, as the AS switch 10 is GND, current will flows from a brake contact point of the relay 18 to terminals 2, 3 of the AS switch 10 and the motor 11 will continue to rotate. Then, if the AS switch 10 turns from GND to IG, both ends of the motor 11 become IG so that the motor is stopped at a determined position.

IPC: H01L21/76
Filed: 1998-12-03
Abstract: PROBLEM TO BE SOLVED: To uniformly planarize an insulating film in the case where the insulating film is formed on a pattern having steps and then is planarized. SOLUTION: Trenches 3 are formed in a Si substrate 1 by using a SiN film 2 having openings in the device isolating regions of the Si substrate 1 as a mask. An oxide film 4 is formed on the Si substrate 1 such that it is buried in the trench 3.

The circuit 3 subjects information signals d to d4 to multilevel modulation by the carrier having a frequency N1f1 from the multiplier and outputs the result to a multiplier 4. Meanwhile, the circuit 6 generates a spread code with the signal having a frequency f1/N2 from the frequency divider 5 as the clock signal and supplies it to the multiplier 4 through an LPF 7. Consequently, spread modulation of the multilevel modulation wave is performed by multiplication of the spread code in the multiplier 4, and the result is sent as an SS modulated wave.

Abstract: PURPOSE:To obtain a product having good quality because of little deformation of a frame having small size and light wt. by transferring reaction at the time of forging to a top frame and a bottom frame through a center frame and a bed and connecting both frames with a column. CONSTITUTION:The bed 2 fixed to the ground 1 and having a pitman 12 vertically moved by rotation of an eccentric shaft 11 at the lower surface is provided.
