Abstract: PURPOSE:To prevent a medium for recording from becoming contaminated or a discharge orifice of a recording head from becoming blocked by providing an ink absorbing element which absorbs extra ink wiped off by a wiping member, and covering the ink absorbing element using a covering material, in the form of a thin plate having through-holes, fixed to the recording head. CONSTITUTION:One surface of ink absorbing elements 3, 4, each consisting of porous resin is fixed to both lateral surfaces of a recording head 1. Each ink absorbing surface 3a, 4a of the ink absorbing elements 3, 4 is formed, in parallel with a discharge orifice surface 1a, at a position which is adjacent to the both sides of the discharge orifice surface 1a and recedes from the discharge orifice surface 1a to the extent of the thickness of covering members 5, 6. The covering members 5, 6 which cover the entire surface of each ink absorbing surface 3a,4a consists of a material having appropriate rigidity and abrasion resistance, and have many through-holes 5. The extra ink sticking to the discharge orifice surface 1a is wiped off by a wiping member 2, then is carried to the sliding contact surface of the covering members 5, 6 and finally is absorbed by the ink absorbing element 3 after passing through the through- holes 5a, 6a.

IPC: H01L21/027
Filed: 1983-08-08
Abstract: PURPOSE:To decide acceptable or defective final electrical characteristics by measuring electrical characteristics at the process of a wafer, to improve final yield and to reduce cost by photoetching an acceptable semiconductor element forming region formed to the surface of a substrate to a star shape. CONSTITUTION:Aluminum is evaporated on the whole surface of a wafer to which an element is formed, a photo-mask with a star-shaped pattern is used, and an electrode is shaped through a photoetching method. Wirings are wired regularly only to a star-shaped section in the electrode, and the whole surfaces of the element are coated with aluminum in regions 21 not masked. Since crystal defect regions in the wafer can be made sure through etching and a final defective region can be grasped from final inspection, the star-shaped pattern can be determined from both results, and the regions 21 coincide with the crystal defect regions. When inspecting electrical characteristics, the regions 21 are decided to be defectives, a sealing to a vessel in a process to follow is suspended, and the whole rate of yield does not lower on the inspection of electrical characteristics after the sealing to the vessel.

Abstract: PURPOSE:To prevent a cover from being deformed or coming off even when a drum is rotated at a high speed for centrifugal hydration, by a method wherein the cover is supported so that it is able to slide along the circumferential face of the drum, and a connector is formed at the edge of the cover and inserted under the brim of a laundry inlet when the cover is closed. CONSTITUTION:To open a cover 38, a hand hole 57 is pushed down to release a stopper latch 56 from a receptacle 53, and in this state, the cover 38 is slid to the opening direction. When the cover 38 is closed, the cover 38 is slid to the closing direction, so that the stopper latch 56 is raised by the slope of the receptacle 53 and automatically connected to the receptacle 53. At this time, a connector 59 slips under the lower part of the mouth of a laundry inlet 34 and engages to the laundry inlet 34. As the connector 59 engages to the lower part of the mouth of the laundry inlet 34, the cover 38 is prevented from being deformed or coming off even when the drum is rotated at a high speed and a centrifugal force is exerted on the cover 38 during dehydrating process.

Title: Designed metal and its production
Inventor: NAKAGAWA TORU
IPC: B05D7/24
Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To obtain a metal having contamination preventability, durability, high reflectibility on heat rays and designing properties by allowing a water-repellant film formed on a metallic base material to contain silicon oxide and molecules having carbon fluoride chains and controlling the thickness of the film to a specified range. SOLUTION: The thickness of the film is 0.07 to 0.6 μm. A metallic base material is coated with an organic soln. in which a methoxysilane compd. or an ethoxysilane compd. which does not contain carbon fluoride chains, a methoxysilane compd. or an ethoxysilane compd. which contains carbon fluoride chains, water and an acidic catalyst are dissolved by a prescribed amt., and baking is executed. Light made incident from the air is partially reflected (reflected on the fixed edge) on the surface of the water-repellant designed film 2 and partially transmits. The transmitted light is reflected (reflected on the free edge) on the metallic base material 1 and progresses from the water-repellant designed film 2 into the air. When the film thickness (d) is given thereto, interference is allowed to occur, and wavelength λ to be increased each other is found, by which the base material seems to be the equivalent color. The film coated on the metallic surface does not so absorb heat rays in the case the film thickness reaches <=0.6 μm.

Title: Sampling pulse generating circuit
Inventor: MATSUDA EIJI
IPC: G11B20/02
Filed: 1977-12-07
Abstract: PURPOSE: To obtain sampling pulses stable to horizontal synchronizing signal by always taking the phase synchronization of sampling with the horizontal synchronizing signal thereby generating clock pulses.  
     CONSTITUTION: A monostable multi 13 outputs the pulse signal of negative characteristics of a pulse width longer than 1/2 of the period of the horizontal synchronizing signal and shorter than 1 at the pulse fall of the TV composite synchronizing signal. This is to make the period of the vertical and horizontal equalization pulses the same as the period of the horizontal synchronizing signal and the fall frequency of each pulse coincides with that of the horizontal synchronizing signal. When the VCO 17 of a frequency multiplier generates the clock pulses necessary for sampling and flows the same to a clock control circuit 10 and frequency dividing counter 18, the circuit 10 makes the same to the output of a sampling pulse generating circuit at the time necessary for sampling and the counter 18 makes them the same frequency as that of the horizontal synchronizing signal and supplies these to a PD 15 thereby making the clock pulses free from any phase difference. Hence, the sampling pulses stable to the horizontal synchronizing signal may be obtained.
