Title: Ink-jet recording head and its manufacture
Inventor: SUEOKA MANABU
IPC: B41J2/05
Filed: 1992-09-09
Abstract: PURPOSE:To enable high-quality and high-reliability recording which can perform high-yield and stable printing, by a method wherein a delivery port is sealed at the time of manufacturing of a recording head at least during a cutting process. CONSTITUTION:A negative type photosensitive dry film is laminated on a base where a thermal conversion element is formed and a nozzle wall 264 is formed by performing patterning by making use of a photomask. Then an adhesive layer is applied thin to a top, to an ink supply port of which a filter is joined by a roll coater and after registeration with a wafer provided with a nozzle, they are joined to each other by a pressing machine. Hereupon, casting ports 268 for casting by corresponding to a casting groove of a padding formed in the top simultaneously with a nozzle pattern are formed on both ends. Then the ink supply port is sealed by a tape. With this construction, neither an inflow of cutting water containing chips within a liquid chamber happens nor chippings on the circumference of a delivery port also is generated. Then the padding is removed by applying ultraviolet rays to the same.

Title: Alignment state inspection device of pin-like part
Inventor: WADA KOJI
IPC: H01G13/00
Filed: 1990-09-13
Abstract: PURPOSE:To automatically inspect an alignment state of a tin-like part held by a holder by inspecting the 'number' and the 'pitch' of a pin-like part using a photosensor and by inspecting whether or not the alignment state of the part is normal. CONSTITUTION:An arm tart 5 is reciprocated at a fixed velocity along an alignment direction A above holders 2, 3 through operation of a controller 7. In the middle of the movement, measurement beam from a photosensor 6 is screened every fixed time by a plurality of diodes D which are held. Therefore, the time when the measurement beam is screened by the diode D is converted to a pulse signal. In the pulse signal, a part showing a fixed peak shows each diode D, respectively. When a pitch between adjacent peaks does not coincide with a fixed pitch, a CPU 19 detects and judges it as 'abnormal', and lights an abnormality display part of the controller 7 corresponding to holding parts (1) to (12) including the diode D of the abnormal peak.

Title: Feeding device for roll paper
Inventor: TAKADA KOTARO
IPC: G03G15/00
Filed: 1987-09-25
Abstract: PURPOSE:To keep the stability of the travel of a recording paper and feed the sheet of recording paper at a uniform speed by providing a movable guide arm which is swingably set on the upper part of a guide plate. CONSTITUTION:A certain quantity of sag is ensured for a recording paper 10 prior to the operation of a cutter 11. When it becomes a cutter operating time, since the recording paper 10 is interposed between the edges of the cutter 11 and fixed, it is gradually stretched. As the recording paper 10 is stretched, a movable arm 16 is also rotated centering around a supporting pin 17 and pushed upward. At the moment when the cutter operating time is over, the sheet of recording paper is stretched to the maximum while the movable arm 16 also reaches its highest point. In this case, since a guide plate 15 has a length larger than the sum of the shortest distance between the cutter 11 and a delivery roller 13 and the feeding quantity of the sheet of recording paper 10 which is conveyed during the cutter operating time, the delivery roller 13 will not fail to send the sheet of recording paper 10.

Title: Roller-type paper feeding device
Inventor: KINOSHITA HIROSHI
IPC: B65H3/52
Filed: 1988-09-27
Abstract: PURPOSE:To stabilize the rotation of the driving group as well as the carrier speed of paper by forming the frictional surface of a friction pad such as to set the frictional force of the downstream side part in the paper carrier direction smaller than that of the upstream side part. CONSTITUTION:Even if a sheet of paper 15 closest to a paper feeding roller 25 is fed into a paper feeding device 22 being attached to the paper sheet conveyed following the rotation of the roller by frictional force, the paper sheet 15 is stopped by a friction pad 25, and conveyance does not take place. Accordingly, paper is conveyed sheet by sheet. Moreover, since the frictional surface of the friction pad 24 is made such that the frictional force of the downstream side part in the paper carrier direction is set smaller than that of the upstream side part, the load provided to the paper sheet 15 decreases gradually when the rear edge of the paper sheet slips out from between the paper feeding roller 25 and the pad, thereby generating no big load fluctuation. Accordingly, in this paper feeding device 22, both the rotation of the driving group and the carrier speed of the paper 15 are stabilized.

Abstract: PURPOSE:To form a striped quasi-mesa structure of substantially same width by making progressively thick the width of a striped mask layer as it goes to the end of a substrate. CONSTITUTION:InGaAsP of 1.3mum oscillation wavelength is employed as a laser active layer 14b, and with side surface etching for the optimum width of the layer 14b taken into consideration the width of a mask 12 is made 1.2 times or more at the opposite ends of a substrate 10 with respect to that at its central portion, and is gradually narrowed up to a location 3-5nm separated away from the opposite ends and is made 2mum at the central portion. With such construction, the active layer 14b has its thickness of 0.9mum or more even along the periphery of the substrate 10 with its substantially uniform width along a striped quasi-mesa structure. Thus, it is usable up to the surroundings of the substrate as a device. Further, it can be prevented from deteriorating over the entire stripe owing to exfoliation of the mask layer, and allows the yield of the resulting device to be improved.
