Title: Ink jet head and unit
Inventor: HIROZAWA TOSHIAKI
IPC: B41J2/05
Filed: 1996-11-13
Abstract: PROBLEM TO BE SOLVED: To minimize the effect of ink leak on the electrical joint of a recording element substrate by providing the recording element substrate with an ink supply port to be coupled with an ink supply coupling part and arranging the joint thereof on the back side of the piezoelectric connecting face of the recording element substrate. SOLUTION: A recording element unit is coupled separably with a drive element unit such that the recording element or a nozzle can be replaced easily upon occurrence of a defect or a failure therein. In the recording element unit, a port 10 for supplying ink into a liquid chamber 14 is made on the side opposite to the electric connecting terminal 8 a thereof, i.e., on the back side, while penetrating a recording element substrate 1b. According to the structure, an ink leaked through a joint is prevented from reaching the electrical joint of the recording element unit and a driving element substrate and thereby the possibility of failure or breakdown of the recording element unit and the driving element substrate due to electrical short circuit is suppressed.

Title: Ultraviolet ray receiving element and ultraviolet ray intensity distribution measuring apparatus
Inventor: DOI TAKASHI
IPC: G01J1/02
Filed: 1994-12-07
Abstract: PURPOSE: To observe the intensity profile of ultraviolet-rays purely optically and improve the noise resistant function by developing photochromism phenomenon to a signal light by radiating ultraviolet-rays and restoring the phenomenon by the signal light. CONSTITUTION: A plurality of light-waveguides 2A are formed vertically and transversely like a lattice to detect ultraviolet-rays 1 which an ultraviolet ray source 32, e.g. a welding arc, etc., emits by using a target produced by mixing and sintering TiO2 and SiO2 on the face of an optical substrate 3, e.g. a glass substrate, etc., as an ultraviolet-ray emitting element. When ultraviolet-rays 1 are radiated to waveguides 2A, Ti<3+> is produced due to photochromism of TiO2 , and signal light-rays with wavelength from a visible light region to a near infrared-ray region are absorbed and attenuated during the transmission and the intensity of the output signal light is lowered.  By stopping radiation of ultraviolet-rays 1, Ti<3+> is lessened by signal light-rays transmitted through the waveguides 2A and absorption is ceased and the intensity of the output signal light-rays returns to the initial value. Since ultraviolet-ray images 20 are focused through an image focusing lens 33 in the waveguides 2A, no optical filter is needed.
