Title: Semiconductor laser module
Inventor: KOSUGI TOMOYA
IPC: H01S5/022
Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor laser module which is improved in cooling performance than the conventional module by contriving the structures of the components of the module, particularly, the structures of the laser setting-up and lens setting-up sections of the substrate of the module. SOLUTION: The upper surface of the substrate of a semiconductor module is composed of two sections having a level difference between them and the height of the upper surface of one section, a YAG-welded lens setting-up section 14b, is made lower than that of the upper surface of the other section, a laser setting-up section 14a, by about the radius of a lens 16. The lens setting-up section 14b is formed in a two-layer state of an upper layer and a lower layer respectively made of two different materials having different coefficients of thermal conductivity and the lower layer part 14d of the section 14b is integrally formed with the laser setting-up section 14a by using the same material.  In order to make the coefficient of thermal conductivity of the material used for forming the upper layer part 14w of the section 14b lower than that of the material used for forming the lower layer part 14d, for example, an iron-nickel-cobalt alloy can used for forming the upper layer part 14u and a copper-tungsten alloy can be used for forming the lower layer part 14d. Alternatively, the lens setting-up section 14b can be formed in one layer by using a different material having a low coefficient of thermal conductivity instead of forming the section 14b in the two layers.

Title: Differential limiting torque controller
Inventor: SHIMIZU KOICHI
IPC: B60K23/04
Filed: 1992-10-30
Abstract: PURPOSE:To secure car deceleration information through highly estimated accuracy by performing car deceleration corresponding control on the basis of a car deceleration operated value found out by way of differentially operating a driven wheel speed turning to a turning outer wheel side in conformity with the discrimination of a tuning direction. CONSTITUTION:At the time of deceleration turning, each driven wheel speed at both right and left sides is detected in both right and left driven wheel speed detecting means (b) and (c), and a turning direction is discriminated in a turning direction discriminating means (d). In a car deceleration operational means (e), the driven wheel speed turning to a turning outer wheel side in conformity with the discriminated turning direction is differentially operated, whereby the extent of car deceleration is found out, and in a target differential limiting torque setting means (f), a target differential limiting torque for stabilizing all car actions according to the car deceleration operated value is thus set up. Then in a differential limiting torque control means (g), a control cod capable of securing the target differential limiting torque is outputted to a differential limiting torque imparting means (a). With this constitution, stability in the vehicle behavior is thus securable through highly controlled accuracy without using any longitudinal acceleration sensor.

Title: Speaking device
Inventor: YOSHIDA TAKEHIRO
IPC: H04M11/00
Filed: 1993-10-28
Abstract: PURPOSE:To reduce the unpleasant feeling caused by the facsimile procedure signal when a speaking device calls a facsimile equipment by reducing the level of a receiving system when a call is produced and then increasing the level after a voice signal is detected. CONSTITUTION:A control circuit 50 transmits a signal to a signal line 50b and sets a prescribed loss to a gain control circuit 10 to reduce the level of the receiving system. Then the circuit 50 sends a designated telephone number to a signal line 50f and generates a calling command pulse to a signal line 50g to call the designated opposite party through a calling circuit 26. When a voice signal is detected after input of the signal of a signal line 20a, a signal is transmitted to a signal line 50b to increase the level of the receiving system. Thus it is possible to reduce the unpleasant feeling caused by the facsimile procedure signal even through a facsimile equipment is connected to the opposite party side and also the circuit loss is small when the speaking device calls the facsimile equipment.

Title: Measuring method and apparatus therefor
Inventor: OOSAKAYA TAKAYOSHI
IPC: H01L21/66
Filed: 1985-12-27
Abstract: PURPOSE:To make it possible to measure the luminous intensity of a second wavelength in an ultraviolet region without using a complicated apparatus, by detecting the concn. of gas, which is formed by generating reaction by the light of the second wavelength, by light having a first wavelength. CONSTITUTION:A light source 10 emits ultraviolet rays A having a wavelength of 254nm and ultraviolet rays B having a wavelength of 185nm. A filter 3 transmitting only the ultraviolet rays A is provided in front of a light receiving element 4. At first, nitrogen gas 9 is made to flow through a measuring cell to detect the intensity I0 of the ultraviolet rays A emitted from the light source 10. Next, when oxygen gas is made to flow through the measuring cell, the oxygen gas absorbs the ultraviolet rays B to form ozone with concn. proportional to the intensity of the ultraviolet rays B. Because ozone absorbs the ultraviolet rays A, the concn. of ozone, that is, the intensity of the ultraviolet rays B is calculated from the output I1 of the light receiving element 4 at this time and the previous output I0.

Title: Pasting device and carton-forming device
Inventor: WATANABE RYOZO
IPC: B31B50/62
Filed: 1996-11-05
Abstract: PROBLEM TO BE SOLVED: To simplify a pasting device by a method wherein a paste feeding means is travelled along the longitudinal direction of the rectangular surface of an object, and the paste feeding means is actuated during travelling intermittently or continuously. SOLUTION: In a pasting process, by rotating a disc through the actuation of a motor P4 , a first and a second guns 7a and 7b are reciprocated in a X- direction. During their travelling in a forward passage toward a vertical wall F1 side, when the first and the second guns 7a and 7b reach a certain speed, the first and the second guns 7a and 7b simultaneously and intermittently actuate. As a result, onto the rectangular surface of an object, paste adheres so as to stand intermittently in lines to the longitudinal direction (X-direction) of the object. Since the first and the second guns 7a and 7b actuate during their travelling at the certain speed, the proper amount of the paste is adhered to the rectangular surface by setting the certain speed to a predetermined speed, at which the proper amount of paste is jetted from the first and the second guns 7a and 7b.

Filed: 1987-11-20
Abstract: PURPOSE:To enable to execute in a short time without the need for burying the sand cylinder using a silica sand of high purity by specifically forming the height from the lade bottom part face to the upper face of a flattened silica sand. CONSTITUTION:The silica sand formed by building up in semi-spherical shape on the lade bottom part 4 is flattened by stamping, etc. and the height (h) from the ladle bottom part 4 face to the silica sand 2 upper face is made to be <=1/5 of the outer diameter of a receiving brick 5.

The upper part of the silica sand 2 is sintered by the molten steel, but the sintered layer becomes in a thin plate shape. As a plate is weak at its strength compared to a spherical shell a plate like sintered layer is easily destroyed by the static pressure of the molten steel, so the natural opening is enabled.
