Patent JP-S6356983-A (JP)
Title: Semiconductor laser device
Inventor: NISHIMOTO HIROYUKI
IPC: H01S5/042
Filed: 1986-08-27
Abstract: PURPOSE:To obtain a modulation bandwidth wider than 10 GHz and excellent reliability, by covering the portion other than the vicinity of a light emitting region with a high resistivity layer, on which a stopper layer is arranged to prevent the diffusion of impurity. CONSTITUTION:On the central protrusion of an N-InP substrate 1, the following are formed in order; i.e. an N-InP buffer layer 2, an InGaAsP active layer 11, a P-InP clad layer 12 P<+>-InGaAsP contact layer 13. Around the protrusion, an InP high resistivity layer 3 and an InGaAsP stopping layer 4 are embedded, on which an InP high resistivity layer 5 an an InGaAsP cap layer 7 are formed in order throughout the whole surface. Impurity diffusion is performed only on the upper part of the central protrusion, and stopped at the P<+>-InGaAs contact layer 13. In this structure, the InGaAsP active layer 11 is surrounded by the high resistivity semiconductor layer 3, so that most of the signal current injected from an electrode metal 9 flows into the InGaAsP active layer 11. Thereby a structure excellent with respect to high frequency response is realized. Further, when a diffusion region of low resistivity is formed by impurity diffusion on the central protrusion, the stopping layer 4 acts as a stopper of diffusion, and thereby the high resistivity is reserved in the high resistivity layer 3 around the active layer 11. Thus the production of superior yield is achieved.

Title: Shut detection method of automatic welding device
Inventor: NISHIMURA SHINGO
IPC: B23K9/127
Filed: 1991-08-13
Abstract: PURPOSE:To obtain a method for detecting a shut of an automatic welding device which can detect the shut positively even in butt welding of a thin plate where a route gap is equal to 0. CONSTITUTION:Normally, a laser beam L which is emitted from a light source 15 is subjected to reciprocating move within a specified length range which crosses a shut WL through a working mirror 17 which rotates within a specified amplitude and this reflection light is received by a sensor 23 and then a difference in the brightness is discriminated at a control portion, thus enabling the shut WL to be detected. Then, when deformation of a base material W due to welding heat becomes relatively large as in the case of butt welding of route gap 0 of a thin plate and then it becomes difficult to discriminate a difference in light and darkness due to this deformation from that according to crossing of the welding line WL, a length of the laser beam L which is projected to a welding portion is reduced by reducing a rotation amplitude of the working mirror, thus enabling the number of measurement points per length to be increased for enhanced resolution.

Title: Formation of protective film on resistor
Inventor: NAKAMURA TOSHIKAZU
IPC: H01C17/02
Filed: 1989-08-04
Abstract: PURPOSE:To form the protective film of a resistor which is superior in size accuracy and weather resistance performance by performing the 1st printing for an insulating material with a screen and then, after drying its printing, performing the 2nd printing for the insulating material with the screen having a wire diameter that is thinner than that of initial screen, and firing insulating materials simultaneously. CONSTITUTION:An insulating material 3, e.g. a glaze and the like, is printed on the surface of an insulating board 1 after attaching a screen that is not shown in Fig. on a resistor 2 which is formed by means of printing and so on and is treated with trimming. After drying the insulating material 3, the screen is attached to the material 3 and then, an insulating material 4 is printed so that it may cover the whole material 3. In the case of the 2nd printing, it is performed by using the screen having a wire diameter that is thinner than that of initial printing. Then, after drying the insulating material 4, insulating materials 3 and 4 which are used for both 1st and 2nd printings are fired simultaneously and a protective film is thus formed. As the thickness of its protective film comes to the prescribed value by the 2nd printing; besides, its side accuracy is determined by the screen with a thin wire diameter that is used for 2nd printing, the size of the protective film can be measured with high accuracy.

Title: Error detection circuit
Inventor: FUJINOBE YASUHIRO
IPC: H04L25/49
Filed: 1985-09-13
Abstract: PURPOSE:To detect the state of disparity such as 5B6B by outputting an error pulse when a state signal of +1 or -1 is inputted consecutively other than the nonuse state signal before one time slot or the nonuse state signal itself. CONSTITUTION:Only when a 2-bit '00' is inputted to a nonuse code detection circuit, the level is at L. Since a OR circuit 6 consists of a NAND gate, the output goes to H and an error pulse is outputted. A memory circuit 2 applies 1 time slot delay to an input '01' or '10' and a Q output of a FF is sent to a AND circuit 4 and a Q output is sent to a AND circuit 5 respectively. Only when an input is '00', L level is fed to the memory circuit 3 and H level is fed in other cases. The circuit 3 retards the input by one time slot and sends the delay signal to circuits 4, 5. When 3-input is all at H level, the circuit 5, 6 sends the output L to a OR circuit 6 to bring the output to H level. That is, when the input is other than '00' before one time slot and '01' or '10' are consecutive, an error pulse is outputted from the output of the circuit 6.

Inventor: MANO KIMIHIRO
IPC: G08B25/00
Filed: 1993-07-27
Abstract: PURPOSE:To acquire a call reason from a slave station without responding to the call from the slave station. CONSTITUTION:The slave station 2 is provided with a sub-address information generating part 22, a master station 1 is provided with a sub-address recognizing part 12, and in the case of detecting abnormal information by the slave station 2 and calling the master station 1, a call reason indicating the abnormal information is added to call information as sub-address information and transmitted. At the time of receiving a call from the slave station 2, the master station 1 recognizses the transmitted sub-address information. Consequently the master station 1 can recognize the call reason from the slave station 2 before responding to the call from the slave station 2 and thereby does not connect a line to a call whose monitoring is unnecessary, so that communication cost can sharply be reduced.

Patent JP-S6358214-A (JP)
Title: Recording device
Inventor: MARUI TOSHIHITO
IPC: B41J29/48
Filed: 1986-08-29
Abstract: PURPOSE:To eliminate a deficit in record by storing data during abnormality occurrence and sweeping them out after normal recovery. CONSTITUTION:When abnormality is detected by an abnormality detection sensor 12, an abnormality signal is inputted to a control means 3 through a photocoupler 13. A means 3 commands a warning means 16 and a recording means to interrupt recording operation. Input digital values to the means 3 during the interruption are written in a memory 4 in order and stored. When the abnormal state is removed, the output of the sensor 12 turns off and the means 3 recognizes that the abnormality is removed. When a rerecording switch 14 is connected, the means 3 sends a recording command to sweep the stored input digital values out of the memory 4 and records during the interruption is restored. Thus, a deficit in record at the time of the abnormality occurrence is eliminated.
