Title: Thermal ink-jet printer head
Inventor: NAKAJIMA MITSUYASU
IPC: B41J2/05
Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To provide a thermal ink-jet printer head which discharges ink drops with an energy as little as possible for forming a necessary dot landing diameter. SOLUTION: An orifice plate is formed in a thickness of 25 μm or smaller, preferably 17 μm whereby a discharge resistance becomes small. A heating resistor is formed to have a relatively small area of 25×25 μm whereby a discharge energy becomes 1 μJ. A ratio of the thickness of the orifice plate and an inner diameter of a discharge nozzle (orifice plate thickness/discharge nozzle inner diameter) is variously changed by variously changing a diameter of the discharge nozzle. Whether a printing quality is good or not is judged through visual measurement. Given that an allowable range of an aspect ratio is from an evaluation level '5' when a landing dot having almost proper diameter and position as a printing dot is obtained to an evaluation level '4' when the position of the landing dot in one-dot range becomes irregular, a proper aspect ratio is 0.75-1.3.  The diameter of the discharge nozzle can be set on the basis of the proper aspect ratio.

Title: Page-turning device
Inventor: MOCHIZUKI AKIRA
IPC: B42D9/04
Filed: 1988-10-05
Abstract: PURPOSE:To obtain an automatic page-turning device simple in construction and reliable by enabling a page-turning means, a fixing means end a restraining means to be rotated on an arbitrary shaft. CONSTITUTION:Driven rollers 2 and page-turning rollers 1 in a page-turning device can be rotated on a shaft 4. When a passbook 17 fed is recognized by a sensor 16, driving rollers 10 are stopped, and the passbook 17 is stopped at a predetermined position. In this case, the driven rollers 2 are moved upward in a direction B, and side plates 19 are rotated in a direction C, whereby the page-turning rollers 1 are lowered in a direction D. When a thick booklet is fed in, the driven rollers 2 are moved upward in the direction B, while the rollers 1 are lowered in the direction D. With the rollers 1 thus lowered in the direction D, the amount of deformation of friction parts 1a of the rollers 1 under compression is increased, and a corresponding reaction force is also increased proportionally. Therefore, a page-turning force equal to the reaction force multiplied by the coefficient of friction between the friction part 1a and the paper is increased.

Title: Manufacture of metal foilclad laminated plate
Inventor: ERIGUCHI HIDENORI
IPC: B32B15/08
Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To efficiently detect a void to obtain only a void-free metal laminated plate by applying specific voltage to an upper and a lower metal foil of a prepreg. SOLUTION: The metal foilclad laminated plate is formed by laminating a metal foil on the upper and the lower face of a prepreg and heating these members under pressure. The prepreg to be used is constituted of a base such as paper, glass woven fabric or glass non-woven fabric and a resin with which the base is impregnated such as an epoxy resin, a polyimide resin, a triazine resin or a modified resin thereof. The metal foil to be used is a copper foil which shows an electrical continuity and is ideally applicable in terms of economy and electrical reliability. In addition, a void which swells at a solder melting temperature or a short-circuiting conductive foreign substance is efficiently detected by applying voltage equivalent to 5-30% of dielectric breakdown voltage of the metal foilclad laminated plate to the metal foil on the upper and the lower face of the prepreg.  Thus is it possible to remove defectives by efficiently detecting the void in the metal foilclad lamination layer with a thin insulating layer and secure the void-free metal foilclad lamination layer.

Title: System for optimizing object by assignment of argument for internal procedure call to register
Inventor: YAMAMOTO HIDEKI
IPC: G06F9/45
Filed: 1991-09-30
Abstract: PURPOSE:To provide the object optimizing method for argument reference and setting of internal procedures with respect to an object generated by a compiler. CONSTITUTION:When compiling a procedure call instruction, a call procedure discrimination processing 1 discriminates whether procedures are internal procedures or external procedures. A main procedure breakable register search processing 2 obtains breakable registers in the case of internal procedures. A breakable register search processing 3 obtains breakable registers. A register assignment determination processing 4 discriminates whether an argument can be assigned to a register or not. An argument-register assignment processing 5 substitutes variables in internal procedures with registers based on a table and deletes unnecessary transfer instructions. Consequently, registers are effectively used at the time of argument transfer, reference, and setting of internal procedures to optimize machine language instructions.

Title: Photovolatic element
Inventor: NAKAJIMA YUKIO
IPC: H01L31/0352
Filed: 1986-10-20
Abstract: PURPOSE:To obtain a photovoltaic element with less deterioration due to light and with capability of stable electric generation, by forming a photovolatic element into superlattice structure in which (i) layers as the first layers and the second layers, whose average coupling energy is different from that of the first layers, are laminated alternately. CONSTITUTION:A (i) layer group 6 made of a-Si is formed into a superlattice structure in which the first layers 7 and the second layers 8, which are smaller in their average coupling energy than the first layers 7, are laminated alternately in numbers. Then electrical defects inside amorphous films, which are generated in the first layers 7, are absorbed into the second layers 8 which are small in their average coupling energy, so that distorted coupling due to optical deterioration is reduced. Output with desired capability of electric generation can be obtained by regulating film thickness of the (i) layer group 6. Hence, a photovoltaic element with long-term and stable capability of electric generation can be obtained.

Abstract: PURPOSE: To automatically fit an inflexible seal by inserting a plunger having a cross sectional shape kept in contact with the seal supported inside a tubular element into the groove of a pipe in an inclined state with the seal inclined by means of an operating means. CONSTITUTION: This device 16 is provided with a tubular element 1 supporting a seal 6 having an outer diameter larger than the inner diameter of the socket 3 of a pipe 4 and the operating means 10 of a plunger 7 inserting the seal 6 into a fitting groove 14. In a first stage, the plunger 7 enters a tubular inside cavity 2 from the initial position of the tubular element 1. A front surface 9 collides with the seal 6 and gradually pushes the seal 6 forward. The tip edge of the seal 6 is forcefully stopped by the fitting groove 14. When a tip section 8 continuously pushes the seal 6, the inclination angle of the seal 6 is gradually increased. A side face 20b is practically kept in contact with the seal 6 and inserts the seal 6. The complete insertion of the seal 6 is attained when a front surface 9 passes over the groove 14 and the seal 6 is completely inserted by the side face 29b.

Title: Ultraviolet prevention type fluorescent lamp
Inventor: SHIBATA HARUO
IPC: H01J61/35
Filed: 1990-09-19
Abstract: PURPOSE:To enable an ultraviolet prevention type fluorescent lamp having larger lamp current density than the predetermined value to be manufactured easily and less expensively without any deterioration in beam and independent of a forming process by forming a specific film on the external surface of a non-linear glass tube. CONSTITUTION:A basic characteristic point common to all compact type fluorescent lamps is that a tube having a smaller diameter than a conventional general lighting fluorescent lamp is used, and ultraviolet radiation becomes large in proportion to lamp current density. The current density of a circular 30W type, largest among conventional fluorescent lamps, is 0.105A/cm<2>, and the present invention is limited to such a lamp as having current density above 0.105A/cm<2>. On the other hand, an upper limit to the current density for the thickness of an ultraviolet absorbing film mainly composed of zinc anode is 3.97mg/cm<2> to keep a beam at the same level as in the conventional ultraviolet prevention lamp. A lower limit is 0.2mg/cm<2> required for the film thickness of smallest 4W type, according to the result of an experiment for the compact type fluorescent lamp. An ultraviolet ray mainly comprising a 365nm spectral line cannot be absorbed by smaller film thickness.
