Title: Pressure control valve
Inventor: MITO AKIO
IPC: F16K17/10
Filed: 1981-03-23
Abstract: PURPOSE:To obtain a control valve which can be operated with small work force by providing an input device, the force of which is opposite to the reaction force of the spring of valve body, and providing backup force to this input device corresponding to the reaction force of spring. CONSTITUTION:The control valve is equipped with a valve body 10, a spring 11 which is a displacement -- force conversion element to push down the valve body, and an input device 12. A mechanism 13 which generates backup force opposing to and corresponding to the reaction force of spring 11 which acts upon the input device 12 is also provided to give the backup force to the input device 12. Accordingly, even if the reaction force of spring 11 is large, load imposed on the input device 12 can be made sufficiently small, and thus high speed operation with small work force is facilitated.

Title: Optical semiconductor element
Inventor: UJI TOSHIO
IPC: H01S5/00
Filed: 1983-03-15
Abstract: PURPOSE:To enable an optical output level to be directly controlled by a single element corresponding to an optical input regardless of laser oscillated beams or naturally emitted light by a method wherein semiconductor layers with low carrier concentration and specific band gap energy Eg comprising semiconductor layers with Eg=Eg2 as main light emitting layers are other semiconductor layers with Eg=Eg4 as main light absorbing layers are formed. CONSTITUTION:When this optical semiconductor element is supplied with current in normal direction, firstly electron - hole are recoupled in the fourth P type InGaAsP layer 25 emitting litht with wave length of around 1.3mum (0.95eV). Due to lower P type concentration in the first, second and third P type InGaAsP layers 22, 23 and 24, the barrier against the fourth P type InGaAsP layer 25 is lowered. Therefore leak current is increased corresponding to increased current saturating the optical output with wave length of 1.3mum with current 10mA. At this time, if optical output with 1.06mum is entered through a window, it is absorbed into the second P type InGaAsP layer 23 to form hole - electron. Corresponding to increased intensity of the entered light, the hole concentration in the second P type InGaAsP layer 23 is increased making hole Fermi level approach to valence band raising barrier against the electron of the fourth P type InGaAsP layer 25.

Title: Optical branching and coupling device
Inventor: YUI MASARU
IPC: G02B6/26
Filed: 1991-02-14
Abstract: PURPOSE:To accurately obtain a desired coupling ratio by arranging electrodes on a substrate so that an electric field can be applied crossing the travel direction of light propagated in optical waveguides. CONSTITUTION:A voltage is applied to the electrodes 4a and 4b to produce the electric field crossing the propagation direction of the propagated light on the substrate 1 between the optical waveguides 3a and 3b. In this area, the refractive index, therefore, varies according to the applied electric field and the ratio of coupling between the optical waveguides 3a and 3b can be varied continuously. The electrodes 4a and 4b are not present on the optical waveguides 3a and 3b. Therefore, the influence of the loading of the electrodes 4a and 4b upon optical characteristics of the light propagated in the optical waveguides 3a and 3b are substantially little.

Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To improve ease of use through controlling of the output state of a setting type illumination load that can be set to multiple operation modes according to an operation, mode, and reporting the completion of the setting of the operation mode by using the setting type illumination load as a reporting illumination load. SOLUTION: When a setting signal of an illuminance sensing mode A from a setting operation part 10 is set in a luminaire 1, a setting signal for a mode B that is one of the illuminance sensing modes is newly transmitted as a remote control signal, and the mode B is thereby set. The mode B allows a setting type illumination load 5 to set its output level smaller than that of the mode A, outputs it during time t1, and thereafter stops the output during time t2. Accordingly, the setting type illumination load 5 is not originally want to output it, but the control part 4 allows the setting type illumination load 5 to output a reporting output as a reporting illumination load 15 for reporting the setting of the mode B.  After the setting completion of the operation mode has been reported, the output of the setting type illumination load 5 is controlled in accordance with the operating condition of the mode B.

Title: Strip for manufacturing material of packing container
Inventor: ANDERUSU SUYOSUTOROOMU
IPC: B65D65/34
Filed: 1993-03-03
Abstract: PURPOSE: To prevent the damage of a pull tab in the formation of strips, the transportation and the like by preventing the pull tab from projecting from a rear edge by forming a cut-out on the longitudinal rear edge of the strip of a material for manufacturing a packaging container. CONSTITUTION: Strips of material for manufacturing packaging container are sometimes provided with aids to opening in the form of pull tabs extending transversely across the strip 1 of the material. When the tab is folded round one rear edge 4 of the longitudinal side of the strip 1, the damage to the projecting tab parts is prevented by the fact that the fold is made round a part of a rear edge 4 provided with a cut-out 7 in the form of an arc of a circle. This is particularly important when the strip is formed into a roll, since the tab parts projecting outside the end surface of the roll can easily be damaged during handling of the roll.
