Patent JP-H11202723-A (JP)
Title: Image forming device
Inventor: ISHIDA NAOYUKI
IPC: B65H85/00
Filed: 1998-01-19
Abstract: PROBLEM TO BE SOLVED: To prevent the opening and closing means of a main body (for example, a carrying unit which can be opened in the outside direction of the main body) from being half opened in a state that an external device is attached, by covering the opening and closing means. SOLUTION: A grip 54b for releasing an engagement state between the carrying unit 53 and the main body 1 is made to project from the outside surface of the unit 53 when an engagement releasing is executed by the grip 54b. Then, a projection part 56 regulating the projection of the grip 54b from the outside surface of the unit 53 when the external device 4 is closed is attached to the external device 4. Therefore, since the grip 54b is not released when the external device 4 is closed, the unit 53 is prevented from being half opened. Besides, when the unit 53 is pressed in the direction of the main body 1 by the projection part 56 through the grip 54b in accordance with the closing action of the external device 4, the grip 54b is pressed by the projection part 56 in a process that the external device 4 is closed.  Then, the unit 53 is engaged with the main body 1 when the external device 4 is perfectly closed. Thus, the half-open state of the unit 53 is eliminated when the external device 4 is closed.

Abstract: PROBLEM TO BE SOLVED: To improve the utilization efficiency of light and to provide a high-luminance liquid crystal device by providing microlenses corresponding to the respective aperture areas of respective pixels on a first substrate on a second substrate and making the width of a light shielding layer corresponding to the switching elements or the like of respective pixels narrower than the line width of data lines or scanning lines on the first substrate. SOLUTION: The plural microlenses are arranged in the shape of matrix corresponding to respective pixel electrodes 11 on a second substrate 2, and a light shielding layer 23 is formed between the adjacent microlenses. This light shielding layer 23 is formed so as to be overlapped with a data line 35 or scanning line 31 in planar view, and its width is narrower than the line width of the data line 35 or scanning line 31. Namely, the contour of the light shielding layer 23 is made back into the data line 35 just by width LB rather than the data line 35 when it is watched from the side of the opposed substrate 2.  Thus, even when the alignment accuracy of both the substrates 1 and 2 or the dimensional accuracy of the light shielding layer 23 is only 1 μm level, the light shielding layer 23 is not protruded into the apeature area, further, the large aperture area can be secured and the utilization efficiency of light is improved.

Title: Variable magnetic permeability type magnetic drive system
Inventor: KATAYAMA AISUKE
IPC: H02N2/00
Filed: 1980-01-29
Abstract: PURPOSE:To generate stable and continous and high drive force by a magnetic unit by generating magnetic energy by means of the variation in the magnetic permeability of the magnetic unit. CONSTITUTION:A variable magnetic unit 2 formed of fluid ferrite or the like is arranged in a gap between stationary magnetic units 1. Further, a magnetic property varying unit 3 is provided at the right side of the magnetic unit 1. When the movable magnetic unit 2 of the fluid ferrite is located in the gap of the magnetic unit 1, the magnetic permeability of the magnetic unit 2 is retained at relatively high value. When the magentic unit 2 moves rightwardly in the gap, the magnetic permeability of the magnetic unit 2 is reduced by the magnetic property varying unit 3. Thus, since the magnetic energy of the magnetic unit 2 is increased, force for reducing the magnetic energy is operated to draw the magnetic unit 2 in the gap of the magnetic unit 1.

Title: Photosensitive material processing device, transporting roller and production of transporting roller
Inventor: MOGI FUMIO
IPC: B29K105/04
Filed: 1994-01-28
Abstract: PURPOSE:To improve drying efficiency without requiring maintenance and exchange, etc., over a long period and to prevent generation of uneven squeezing at the time of intermittent processing. CONSTITUTION:Squeezing rollers 60, 61 applied to an emulsion surface side are formed by machining roller body surface layers made of a closed cell foamed resin, opening the closed cells on the surfaces and forming open pores on the surfaces. The squeezing rollers 60A, 61A on the emulsion surface side are capable of swiftly sucking water from a film F like a sponge roller 4. The sucked water is not absorbed into the rollers and is returned to a washing tank, etc., by flowing on the surfaces. The squeezing rollers 60A, 61A absorb a large volume of water and are not contaminated. The volume of the water to be held in the water absorbing rollers is extremely little even if the rollers are used for a long time and, therefore, the thickening of the liquid does not arise and uneven squeezing does not arise.

Title: Output voltage detector for inverter
Inventor: MORI MASATO
IPC: H02M7/48
Filed: 1990-01-18
Abstract: PURPOSE:To detect on which side of DC power source a voltage at an output end of an inverter by a method wherein a voltage is detected as appearing at the output end of the inverter to be compared with a reference voltage and an output of a comparison means is averaged. CONSTITUTION:A voltage waveform appearing at an output end N is turned to an intermediate voltage with resistances 11 and 12 depending on a direction of current i+ and i- flowing through a load 4 and compared 14 with a reference voltage. When a voltage at the output end N is H, an output of a comparison means 14 goes to L and current flows from a power source potential point V1 to let a light emitting element 16a, which turns ON a photo detector 16b. Current flows to an output end 16c from a power source potential point V2 and a capacitor 19 begins to be charged to raise a voltage detection signal. When the voltage at the output end N is L, the voltage detection signal lowers. Hence, a mediam is obtained corresponding to a ratio of H to L. In other words, a waveform as given when the capacitor 19 is charged or discharged indicates the output end N is connected to a positive (negative) side of a DC power source 1. An average output voltage at a cycle can be detected by charging and discharging time.

IPC: D21H17/29
Filed: 1995-01-24
Abstract: PURPOSE: To obtain both a new cationized starch and a new size for papermaking having a low cationic equiv. in spite of a high nitrogen content possessed thereby and further a low size viscosity while maintaining a high molecular weight. CONSTITUTION: The cationized starch and size are substituted with a quaternary ammonium salt and/or a tertiary amino group. The relationship between the nitrogen content of the cationized starch derived from the quaternary ammonium group and/or tertiary amino group in the catinized starch [X(%): (a measured value obtained by a semimicro Kjeldahl method)] and a cationic equiv. value of the size Y (mequiv.): [a measured value obtained by colloidal titration using potassium polyvinyl sulfate (PVSK)]} satisfies Y<0.70097X-0.00495 in the case of a natural terrestrial stem starch, Y<0.32936X-0.00495 in the case of a natural subterranean stem starch having ester type substituent groups and Y<0.40942X+0.02211 in the case of a natural subterranean stem starch without any ester type substituent group.

Title: Shell and tube type evaporator
Inventor: ABE NORIMITSU
IPC: F28F13/12
Filed: 1987-01-20
Abstract: PURPOSE:To prevent the heat exchange efficiency of the evaporator from being largely lowered in a separate flow region and further to suppress the increase in pressure loss to a minimum value by inserting in a tube axial direction a stirring member into a clearance on the outside of a heat transfer tube in a region where the fluidizing mode of a fluid to be evaporated flowing within a shell is a separate flow. CONSTITUTION:A region of a separator flow produced in the step of the flow of a fluid to be evaporated flowing within a shell 1 while evaporating is produced in the vicinity of an inlet for the fluid to be evaporated of the shell 1, that is, a position where the fluid to be evaporated is easily dried. Accordingly, when a torsion plate 4 is inserted in the vicinity of the inlet for the fluid to be evaporated, the fluid L to be evaporated flowing at the lower part of the shell 1 is swirled up to the upper part of the shell 1 by the stirring effect of the torsion plate 4 to wet the dry surface of the heat transfer tube 2 disposed at the upper part of the shell 1. For this reason, it is possible to prevent the heat exchange efficiency in the separate region from being largely lowered. Further since the torsion plate 4 is inserted only in the vicinity of the inlet for the fluid to be evaporated, the pressure loss is only slight.

Title: Transformer
Inventor: KIYOHARA AKIHIKO
IPC: H01F27/245
Filed: 1980-01-29
Abstract: PURPOSE:To simply reduce the leakage flux and to prevent the generation of the vibratory noise of the subject transformer by a method wherein the width of the bottom leg on the E type core made of a grain-oriented silicon steel plate is made by the prescribed magnification of the width of the side leg. CONSTITUTION:When the width of a center leg 2 on the E type core 8 is b, the width of the bottom leg 3 is c, the width of the side leg 10 is d and the width of an I type core 9 is e, c=1.15d-1.30d is obtained. With c=1.12 or thereabout, the vibratory noise is reduced to the degree that is does not cause trouble and when it is above c=1.30d, the leakage flux becomes extremely small due to saturation and becomes equivalent thereto. Accordingly, by taking into consideration of safeness, the width c is set at 1.15 times or above of the width of the side leg 10, and it is to be maintained below 1.30 time not to have a large-sized transformer maintaining the same efficiency. As a result, the leakage flux is simply reduced and the generation of the vibratory noise can be prevented.
