IPC: B41J2/16
Filed: 1991-09-19
Abstract: PURPOSE:To constitute the title method so that sticking of piezoelectric elements each to cavities each is performed easily, by a method wherein after a large-sized and single piezoelectric element which sits astride of a large number of cavities is fitted to the head in the lump, the piezoelectric element is split into a large number of small piezoelectric elements corresponding to the cavities each. CONSTITUTION:A large-sized and single piezoelectric element 20 covering the whole cavities is fitted to an ink-jet printer head 1 having a large number of the cavities in the lump. Then the large-sized and single piezoelectric element 20 is split into large numbers by laser processing. In other words, the large-sized and single piezoelectric element 20 is split into a large number of small piezoelectric elements 21-28 corresponding respectively to the cavities each at parts 31-37 where is no piezoelectric element. Since the piezoelectric elements 21-28 are independent electrically of each other, respective electrodes are driven separately, through which the cavities each corresponding to the electrodes can be operated without causing the other piezoelectric elements 21-28 to interfere with the cavities. With this construction, sticking of the piezoelectric elements 21-28 is performed simply in the lump.

Abstract: PURPOSE:To prevent filming of a toner on the surfaces of a developing sleeve and a photosensitive body and fogging on an image by mixing a specified fluorinated compound with the toner and allowing it to be adsorbed to the surface of the toner by an outside addition process. CONSTITUTION:The adsorption power of the fluorocompound to the surface of the toner is remarkably increased by forming >= 2 parts in the molecule of the compound to be adsorbed to the surface of the toner and to exhibit the addition effect sufficiently without changing the mixing ratio with the lapse of time. The fluorocarbon compound to be added to the toner comprising a binder resin and a colorant is represented by formulae I and II in which each of R1 - R6 is F, COOH, COONa, or the like, and (n) is an integer of >= 2, thus permitting the obtained toner to prevent film forming due to melt attaching of the toner to the surfaces of the developing sleeve and the photoconductive sensitive body and to form an image free from fog.

Title: Method for attaching discharge port with ultrasonic wave
Inventor: YAMADA KAZUKI
IPC: B29C65/08
Filed: 1997-08-20
Abstract: PROBLEM TO BE SOLVED: To attach a discharge port in even a cold state to a container without damaging a thin part by applying ultrasonic vibration of specific frequency to a connecting surface of a flange of the port to the container, and welding the flange to the container. SOLUTION: In an ultrasonic sealing apparatus to be used, the frequency of ultrasonic wave to be given to a connecting surface of a flange 1b of a discharge port 1 to a container 2 by an ultrasonic horn 15 is set to 25 kHz or more. The flange 1b of the port 1 is ultrasonically vibrated by the horn 15 during ultrasonically sealing of the port. This vibration is propagated from the flange 1b to an inner shield 1c. In this case, since the frequency is set to the 25 kHz or more, the vibration is abruptly attenuated while propagated through the shield 1c, and hence not so propagated to a thin part 1d. Therefore, the part 1d is not damaged by the vibration.

Title: Manufacture of semiconductor device
Inventor: NOJIRI KAZUO
IPC: H01L21/76
Filed: 1984-11-16
Abstract: PURPOSE:To obtain an element isolating layer having a fine width, by providing a first mask on an SiO2 film, coating the side surface by a second mask, opening a hole in an SiO2 film, and performing selective oxidation. CONSTITUTION:On a thermal oxide film 2 on a P type Si substrate 1, Si3N4 3 and SiO2 4 are laminated. A resist mask 3 is applied. Dry etching is performed and a first mask 4a is formed so that l1=l2=1mum is obtained. SiO2 6 is overlapped, and RIE is performed. A second mask 6a is formed on the side surface of the mask 4a. After B ions are implanted, the masks 4a and 6a undergo wet etching and the masks are removed. Then the side surface of the SiO2 under the Si3N4 mask 3a is etched by about 0.02mum. Then selective oxidation of the substrate 1 is performed, and an isolating layer 8 is formed. Bird's beaks 9 are formed on both sides. The width l5=0.4mum of the window of the mask 3a is added to the beak widths 0.3mumX2 on both sides, and the isolating layer 8 having the width 1mum is obtained.

Title: Load detector
Inventor: KUSAKI TAKAMI
IPC: G01L1/26
Filed: 1985-10-29
Abstract: PURPOSE:To enable a load detector to be prevented from the deterioration of performance or from a breakage even when an excessive load is applied to the detector by bringing a pin-shaped member into contact with part of an inner wall when the load exceeds a rated value. CONSTITUTION:When an excessive force F shown by an arrow is applied to a rigid body portion 3, flexible beams 4 and 4' are deformed and the rigid body portion 3 is displaced relative to another rigid portion 2. Therefore, the portion of an opening 21 belonging to the rigid body portion 3 is also displaced and the connecting portion j1 between a slit 16 and the opening 21 and a pin 22 are brought into contact with each other. When a displacement is further continued, the connecting portion j1 presses down the pin 22 to bring the pin 22 and another connecting portion j2 into contact with each other at last. Although the force F, because large, tends to further deform the flexible beams 4 and 4', since the connecting portions j1 and j2, that is, the rigid body portions 2 and 3, respectively, are in a condition to be connected to each other via the pin 22, thereafter, the force F is directly transmitted from the rigid body portions 2 to 3 without through the flexible mean 4 and 4'. Thus, even when a large load above a rated load is applied, no excessive stress is produced in the flexible beams and a load detector can be prevented from the deterioration of performance and from a breakage.

CONSTITUTION:A laser section 8 having a stripe-shaped current injecting region 5, and a monitor section 9 are together monolithically integrated in the same substrate 1, with the laser section 8 and the monitor section 9 being electrically separated each other. A trench 10 for separation is formed with the sidewall 11 on the side of the laser section perpendicular to a p-n junction while the trench being formed with the sidewall 12 on the side of the monitor section inclined at 40-50 deg. to the p-n junction. As a result, the emitted laser beam 14 from the laser section 8 is reflected by the sloped sidewall 12 on the side of the monitor, and thus the reflected laser beam 14 is emitted outward with being perpendicular to the p-n junction, thereby the semiconductor laser with monitor can be easily coupled to any optical fibers. Moreover, since a reflecting film 16 with high reflectance is formed on the far-end surface, the threshold current of the laser can be effectively reduced.
