Title: Recording head
Inventor: SUWABE YASUSHI
IPC: B41J2/015
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To provide a recording head capable of recording a high resolution image by ejecting small ink drops without using a nozzle. SOLUTION: When an input signal from a signal generating means 32 is inputted to a vibration generating means 24 in accordance with an image signal, a piezoelectric vibration section 34A of an elastic section 34 is vibrated, thereby causing bending vibration of an elastic section 34B. As a result, a portion in the vicinity of a tip section 34C of the elastic section 34B is subjected to the bending vibration having the large amplitude to generate a capillary wave so that small ink drops are continuously ejected one by one.  As the elastic section 34 is equipped with the piezoelectric vibration section 34A as a piezoelectric vibrator element and the elastic section 34B as an elastic member and an adhesive face or another member (such as an adhesive) is not provided between the piezoelectric vibration section 34A and elastic section 34B, the vibration of the piezoelectric vibration section 34A is not attenuated so that it is directly transferred to the elastic section 34B.

Abstract: PURPOSE:To obtain a semiconductor device having a capacity part of high capacity value per unit area and excellent in electric insulation by making a substance, in which composition of a silicon nitride oxide film is changed in the film thickness direction, a capacity insulating film. CONSTITUTION:After forming a lower part electrode consisting of polycrystalline silicon on a silicon substrate and removing a natural oxide, an SiOxNy film is made to grow by reduced pressure chemical vapor growth using a consisting of N2O, SiH4 and NH3. At this time, the SiOxNy film changes its composition by previously studying the releration between the flow rate ratio and the composition ratio and changing the gas flow rates during growth. Then, a capactor insulating film having a composition distribution such that the content of oxygen increases towards both ends in the film thickness direction is formed to the thickness, for instance, 6.5nm, laser an upper part electrode made of polycrystalline is formed to constitute a capacity part. The capacitor insulating film formed in this way becomes about 5.5nm in terms of the film thickness of SiO2.

Title: Radiation thermometer
Inventor: ONO AKIRA
IPC: G01J5/60
Filed: 1980-03-28
Abstract: PURPOSE:To measure accurately the temperature of the object to be measured remotely without causing the device to approach this object, by constituting the simple device using an intensive radiation source for irradiation which oscillates in one wavelength band and a radiation detector which detects radiation in two wavelength bands. CONSTITUTION:Radiation of wavelength lambda1 is generated from intensive radiation source 1 for irradiation which oscillates in one wavelength band, and this radiation is irradiated to object 4 to be measured after chopped intermittently by chopper 2. Object 4 absorbs the energy of irradiation in proportion to the absorptivity in wavelength lambda1 and generates the temperature change. Heat radiation generated from object 4 is divided into two by radiation detector 8, and one is detected through interference filter 7, which permits wavelength lambda2 to pass through, by radiation detector 8, and the other is chopped intermittently synchronously with chopper 2 by chopper 9 and is detected through interference filter 10, which permits wavelength lambda1 to pass through, by radiation detector 11. Thus, the temperature of object 4 is measured accurately remotely without approach to object 4.

Abstract: PROBLEM TO BE SOLVED: To eliminate the scattering of a filthy water generated in a washing part over washed egg shells, avoid becoming unsanitary and increase sterilization effect by separating the first carrier device for washing egg shells and the second carrier device for sterilizing and drying the egg shells. SOLUTION: The washing section where the first carrier device 2a is placed and the sterilizing drying section where the second carrier device 3a is placed to spray ozonous water over egg shells for sterilization and subsequently to dry the egg shells, are separated, for example, by partitioning with a wall or by enclosing both the sections separately in a casing. Thus, the spray of the filthy water generated in the washing section does not come into the sterilizing drying section, and further the sterilization is efficiently carried out.

Title: Steam desuperheating piping
Inventor: UEKI KENJI
IPC: F22G5/12
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To prevent damage caused by a heat stress of a piping as pressure containing part by providing a means for turning steam on the upstream side from a position of spraying water to shorten an evaporation range of water spraying. SOLUTION: A means for turning steam is formed at an inflow part of steam 3 to a steam desuperheating piping 1. Steam 3 running into the steam desuperheating piping 1 after flowing through a steam pipe 2 being straightened turns to a spiral flow 4 at a connection part of the steam pipe 2 and the steam desuperheating piping 1 as inflow part. The spiral flow 4 flows to the downstream side through the steam desuperheating piping 1. On the other hand, spraying water 5 is sprayed into the spiral flow 4 of the steam in the steam desuperheating piping 1 from a spray nozzle 7 passing through a spraying water pipe 6. The steam in the steam desuperheating piping 1 as spiral flow 4 has a high effect to heat the spraying water sprayed from the spray nozzle 7 for evaporation thereby reducing an evaporation area V in the steam desuperheating piping 1.
