Abstract: PURPOSE:To densify nozzles while holding the positional accuracy thereof without using special parts, by constituting the title recording head so that two head substrates each having a nozzle part and a flow passage forming part and having a specific outer shape of a specific dimension are formed on the surface of the same substrate in a superposed state. CONSTITUTION:The outer shape of each of head substrates 1 forms a line symmetric shape with respect to a center line (a) and a flow passage forming part consisting of a pressure chamber and a supply preparation chamber except the vicinity of a nozzle part is constituted so as to have an almost symmetric shape. Nozzles are formed so that the line (b) passing the center of the nozzle positioned at the central part is shifted by a distance 1/4 a nozzle interval T2 with respect to the center line (a) becoming a symmetric line at the leading end parts of nozzles arranged at an equal interval. Further, by assembling electrodes composed of metal plates, piezoelectric elements, wirings and a head cover, an ink jet head is constituted. That is, by superposing two head substrates in such a state the leading end parts of the nozzles are shifted by the distance 1/4 the interval of the nozzle with respect to the symmetric axis, the densification of the nozzles can be achieved easily.

Abstract: PURPOSE:To perform the simultaneous use and change-over use of a radio wave and a light wave without lowering the functions of both radio wave and light wave systems, by providing an optical system to the peripheral space part of a radio wave array antenna arranged in a planar state. CONSTITUTION:The radio wave signal from a transmitter 3 is supplied to an array antenna 1 by a duplexer 2 to be emitted to a space. The reflected signal from a target passes through the route reverse to that at the time of transmission to be sent to a receiver 4 by the duplexer 2 and the detection of a target signal is performed by a signal processor 5. The light wave allowed to radiate from the target is converted to an electric signal by a light wave detector 7 through the optical system 6 provided to the space part 10 of the peripheral part of the antenna 1. The light signal from the target converted to the electric signal is sent to a signal processor 9 through an amplifier 8 to perform the detection of a target signal. As mentioned above, by allowing the radio wave system and the light wave system to function independently each other, the effect exerted on the capacity of the radio wave system such as the lowering in the gain of the antenna 1 or the deterioration of side robe capacity becomes min. and, even when both radio wave and light wave systems are arranged in parallel, the lowering in the functions of both systems can be prevented.

Title: Inspection apparatus for shedding operation of loom
Inventor: MAENAKA KIMIHIRO
IPC: D03D51/46
Filed: 1988-07-21
Abstract: PURPOSE:To remarkably improve the operation rate of a loom by comparing a target shedding angle signal with a shedding angle signal determined from a mechanical angle signal and a warp-detection signal transmitted from a light- projection and receiving elements oppositely positioned on both shed faces, transmitting a deviation signal based on the compared result to determine the real speed of the shedding motion and correcting the motion. CONSTITUTION:A light-projection element and a light-receiving element are oppositely placed on both sides of a shedding face. A warp-detection signal transmitted from said light-receiving element and a mechanical angle signal of a loom measured by an encoder are inputted. When warp is absent in the weft-flying path, the state is detected as a shedding angle signal and displayed on a display. Said shedding angle signal is compared with the target shedding angle signal and a deviation signal is outputted. When the level of the deviation signal is higher than a prescribed level, a stop signal is transmitted from an additional circuit to stop the loom. When the shedding angle signal is larger than the weft-insertion starting angle signal, the above deviation signal detection operation is locked to numerically determine the real speed of the warp shedding angle.

Title: Recorder and recording method
Inventor: KAN FUMITAKA
IPC: B41J2/05
Filed: 1986-08-05
Abstract: PURPOSE:To enable high speed recording by providing an electron beam generator which generates an electron beam for ejection of a recording liquid through a heated nozzle. CONSTITUTION:Electrons generated from an electron beam source EBn by projecting an acceleration voltage into a nozzle W are projected to Wn (n=1, 2...) to heat Wn and at the same time, electrically charge a recording liquid IK in a nozzle Wn. If a heating part H becomes hot at a higher temperature than the evaporation temperature of the recording liquid IK in the nozzle W, bubbles B generate in the heating part H, resulting in the rapid increase of a pressure in the nozzle W. At the same time, part of the recording liquid which exists in a part between an orifice OF and the heating part H is discharged from the orifice OF. The discharged recording liquid becomes liquid droplets which are charged by a high voltage applied to the nozzle W. The liquid droplets hit recording paper A soon to cause a recording liquid to adhere to the surface of the paper. The recording liquid is replenished from a recording liquid supply direction on the orifice OF side and its opposite side following the contraction of the volume of the bubbles B by cutting off the electron beam which is projected to the heating part H.
