Title: Ink jet head
Inventor: NARUSE OSAMU
IPC: B41J2/135
Filed: 1985-02-13
Abstract: PURPOSE:To contrive an assembling work to be made easy and a mass productivity to be improved by making a construction of a head section of an ink jet recording apparatus to be a modular system. CONSTITUTION:This ink jet head is made into a modular system with a head body 1, a nozzle plate 2, and a vibrator 3 being formed integrally. The sizes of the outside diameter D and a length L of the head body 1 are determined such that the D and the L are made larger than a resonance frequency by 5-20% previously, since the resonance point is determined by these sizes, and in the forming time thereof, the vibrator 3 is inserted into the head body 1 and formed integrally. A fusion between the nozzle plate 2 and a resin is difficult since the former is composed by metal. A resin coating or a bonding material is applied to a position where the nozzle plate is removed previously, then the injected resin is melted thereon, since the nozzle plate 2 is made of metal and it is difficult to be melted with the resin. In this manner, an effect of a mass productivity can be obtained by reducing a number of parts of the head construction and simplifying thereof.

Title: Optical coupling structure of optical semiconductor element and optical fiber
Inventor: HORIMATSU TETSUO
IPC: G02B6/42
Filed: 1987-02-06
Abstract: PURPOSE:To raise the optical coupling efficiency by sticking the end face of an optical fiber and the end face of an optical semiconductor element through an optical adhesive agent provided with a refractive index being roughly equal to a refractive index of a core of the fiber. CONSTITUTION:At the time of assembly, first of all, an optical adhesive agent 20 is dripped down to an optical semiconductor element end face 5, and the adhesive agent 20 is placed in a dome shape on the element end face 5. Subsequently, a fiber end face 10A is allowed to be adjacent to the element end face 5, and in a state that the fiber end face 10A has abutted on the top part of the adhesive agent 20, an optical fiber 10 is adjusted as to its movement on the surface being parallel to the element end face 5, and after the adjustment has been ended, a relation position of the optical fiber 10 and a photoconductor 1 is fixed by hardening the adhesive agent 20. As for the optical adhesive agent 20, that which has a refractive index being roughly equal to a refractive index of a core 11 is selected, therefore, in case the optical semiconductor 1 is a photodetector, when a reflected light by the fiber end face 10A is monitored by connecting the optical fiber 10 to a light source, the reflected light is abundant before the fiber end face 10A abuts on the optical adhesive agent 20, but when the fiber end face 10A abuts on the adhesive agent 20, this reflected light scarcely exists.

Title: Interruption detecting method of supply of items to be incinerated in fluidized-bed incinerator
Inventor: ZENBOU ISAHARU
IPC: F23G5/50
Filed: 1990-02-06
Abstract: PURPOSE:To properly detect an interruption of supply of items to be incinerated to a furnace, and stabilize the operation by a method wherein radiant heat energy generated by primary combustion is measured, and when the measured value drops below the specified set value, it is judged that supply of the items to the furnace is interrupted. CONSTITUTION:A radiant heat thermometer 38 is installed in a furnace 11 to measure radiant heat energy generated by primary combustion. In the case the supply of items G to be incinerated is interrupted and the measured value of the radiant heat thermometer 38 drops below the specified set value, the conveying speed of a screw conveyer 18 is increased by a controller 39 to supply the items G quickly and water supply from nozzles 35 is stopped to prevent a fall of the temperature of fluidized medium S. A signal is sent to a primary air flow controller 23 and a secondary air flow controller 28 so that the primary air flow is limited to the minimum requirement value and the secondary air flow is reduced. As a result, a stable operation can be carried out without hindrances such as a sharp reduction in the steam generation amount and an excessive drop of the temperature of the fluidized medium S caused by interruption of supply of the items G to be incinerated.

Title: Hardening method by laser
Inventor: MEGURO TAKASHI
IPC: C21D1/09
Filed: 1981-02-25
Abstract: PURPOSE: To adjust the rate of absorption to hardened parts and to produce hardened parts of good quality at a low cost with high accuracy in laser hardening by removing the laser absorbing material films of the parts vulnerable to overheating and melting or controlling the thickness thereof.  
     CONSTITUTION: An absorbing material film of about 15W30μ is formed on the hardened surface of a gear, after which the absorbing material film of the tooth crest which is of a high rate of absorption of laser and is vulnerable to overheating is removed thoroughly, or is controlled to about 0W5μ thicknesses, after which laser hardening is executed under conditions permitting sufficient hardening down to the bottom land. Thereby, the respective parts of the gear are heated almost uniformly, whereby the good quench-hardened layer is obtained. In some cases, the requlation of the angle of laser irradiation to the hardened face gives equally good results.

Title: Graph code
Inventor: KAKI HIROAKI
IPC: B42D15/10
Filed: 1987-02-09
Abstract: PURPOSE:To show a numeric character of a large digit number in a space smaller than a 'Karlar code' by rearranging four squares forming a square with cross partially shown by figure (a) in a single longitudinal row against a bar code so that the lateral space extension is reduced. CONSTITUTION:A numeric character can be specified by painting out either one of four squares. This specification of numeric characters can be standardized by applying a rule defining that the four squares 1, 2, 3 and 4 are painted out with preference in the order of larger values. A 'column' obtained by painting out all four squares is set on the forefront row of another 'column' in consideration of the use of an optical reader (scanner). Thus the start point of the corresponding code is shown. Thus said 'column' containing four painted-out squares is also used to show a section between both numeric characters and the numeric characters of >=2 different groups can be shown. Furthermore the lateral space extension of a code can be suppressed by changing four regular squares into four rectangles.
