Title: Communication equipment
Inventor: OYANAGI HIROYUKI
IPC: H04M3/42
Filed: 1990-09-04
Abstract: PURPOSE:To facilitate an operation as against the acquisition of a line at an external device by releasing the line holding state of a main device when a line holding release request is outputted to the main device from the external device in a state where the line is held in the main device. CONSTITUTION:When a system is set to the line holding state by the operation button 2 of the main device 1, the release request of the line holding state (the hooking of the external device or a special number dial tone, for example) is outputted to the main device from the external device. When it is detected, the control circuit 11 of the main device releases the line holding state and connected a line wire with the external device 3. Thus, the line holding of the main device can be released by outputting the request of line holding release to the main device when the line is acquired in the external device after the line holding state in the main device. Thus, the operation for the acquisition of the line in the external device is facilitated.

Title: Elliptic polarizing plate and liquid crystal display device
Inventor: NAKAMURA TAKU
IPC: G02B5/30
Filed: 1994-09-29
Abstract: PURPOSE: To obtain an elliptic polarizing plate with reduced stiching processes, causing no stripping, bubbles nor wrinkles even under a high humidity condition by using an optical anisotropic element provided with an optical anisotropic layer containing a disk like compound on a saponified cellulose triacetate. CONSTITUTION: The elliptic polarizing plate is composed of at least a polarizing element and the optical anisotropic element provided with the optical anisotropic layer containing the disk like compound on the saponified cellulose triacetate. The sticking processes at the time of forming the elliptic polarizing plate are reduced by using the optical anisotropic element as a protective film of the polarizing element.  Though it is thought that the remarkable difference of shrinkage property by heat or humidity between the stuck optical anisotropic element and the polarizing plate results in stripping defect, wrinkle deffect, bubble defect or the like on the stuck boundary, the defects are prevented by providing the optical anisotropic layer containing the disk like compound on the supporting body and using the cellulose triacetate, which is conventionally used as the protective film of the polarizing plate, as the supporting body for the optical anisotropic element.

Title: Method and apparatus for removing phosphorus in water
Inventor: MATSUNAGA AKIRA
IPC: C02F11/04
Filed: 1993-09-22
Abstract: PURPOSE:To provide a dephosphorization method and apparatus in which the dephosphorization function is maintained without troubles by dephosphorizing the dewatering filtrate of digested sludge even when DO in inflow water is elevated with the decrease in phosphorus concentration in water to be treated. CONSTITUTION:A dissolved oxygen meter 40 and a flow meter 41 are installed in inflow water 11; a dewatering filtrate temporary storing tank is equipped with a pH meter 43, a pH feedback controller 44, and an alkali injection device 45. A polymeric coagulant is injected to concentrated digested sludge which was digested in an aerobic-anaerobic tank 42, and the sludge is dewatered with a dewaterer 25. The reagent injection ratio is calculated on the basis of the stoichiometric relationship between phosphorus and a dephosphorization reagent obtained from the data on the phosphorus concentration in the dewatering filtrate and the dissolved oxygen in the inflow water. The final reagent injection ratio is determined by multiplying the calculated reagent injection ratio by the data on the flow rates of the dewatering filtrate and the inflow water. In this way, the treatment to make phosphorus insoluble is conducted by injecting the reagent to make phosphorus insoluble to the dewatering filtrate, providing the dephororization method and apparatus.

Title: Cleaning tape
Inventor: YASUDA JUN
IPC: G11B5/008
Filed: 1984-11-08
Abstract: PURPOSE:To clean a magnetic head without damaging it unnecessarily by repeating alternately a magnetic head cleaning tape which becomes shorter slowly and a picture quality checking tape. CONSTITUTION:The titled tape is constituted such that more than one set of the picture quality checking tape and the magnetic head cleaning tape which becomes shorter slowly from its tip are alternately repeated. The magnetic head is cleaned by the magnetic head cleaning tape 1 first time, and then the picture quality is checked by the picture quality checking tape 2 first time. However, when the cleaning is not carried out, the tape is further advanced to clean the magnetic head. The necessity of the cleaning is less compared with the initial step. Here the 2nd cleaning is executed. However, if the cleaning is finished on the way, the polishing amount of the magnetic head is decreased, because the magnetic head cleaning tape 1 is shorter than the magnetic head cleaning tape first time. Accordingly more appropriate cleaning can be carried out.

Abstract: PURPOSE:To enable EGR control in response to a deterioration condition of a diesel engine by shorteningly compensating an exhaust gas reflux rate to an operation condition in response to decrease inside pressure of the engine detected with an in-cylinder pressure sensor. CONSTITUTION:In an ECU 20, signals of an engine speed sensor 22 provided at a fuel injection pump 21 and an acceleration opening sensor 23 are inputted.

Opening of an EGR valve 6 is controlled so as to perform exhaust gas reflux(EGR). The exhaust gas reflux rate is shorteningly compensated in response to decrease of pressure in a cylinder of the engine 1 detected by an in-cylinder pressure sensor 29, that means a secular change of the engine 1. Consequently, discharge of NOx is decreased without deterioration of HC, smoke exhaust characteristic, fuel consumption characteristic and the like.

IPC: G03B9/10
Filed: 1998-08-21
Abstract: PROBLEM TO BE SOLVED: To provide a shutter for a camera constituted so that the lowering of exposure accuracy may be restrained to be small even though two shutter blades turning reciprocatively bound when their opening actuation is stopped at a specified aperture position by an aperture regulating member. SOLUTION: The opening actuation of the shutter blades 17 and 18 is stopped by making the abutting part 17c of the blade 17 abut on the regulating pin 14e of the aperture regulating member 14. The shape of the aperture at such a time is regulated by line segments A, B, C, D, E and F, and the line segments A and D are the circular arcs of concentric circles, and the center is the driving pin 12d of an opening/closing member 12 fit in the long holes 17a and 18a of the blades 17 and 18. Therefore even though the blades 17 and 18 bound and are vibrated when the abutting part 17c abuts on the pin 14e, they exert influence on aperture area only in the actuating directions of the blades 17 and 18.
