Title: Circle-to-straight line converting optical device
Inventor: HASEGAWA OSAMU
IPC: G06K7/10
Filed: 1980-05-30
Abstract: PURPOSE:To increase the light intensity on optical axis by forming the end faces of the optical fibers which constitute a circle to straight line converting device and are arranged in a linear shape into a spherical shape. CONSTITUTION:End faces of optical fibers 11 are once metlted by heating and spherical faces are obtained by the generated surface tension. If they are optical fibers made of quartz, they are generally constituted of multielement glass and therefore they can be melted when heated to about 650-800 deg.C. For the optical fiber groups which have already been arranged into a linear shape by resins or the like, they can be melted, if they are heat-treated by scanning or the like of, for example, a burner or the like. By such operations, the end faces of the fibers 11 are made into a spherical lens (convex lens) shape, whereby the diffusion of light outputs is prevented and the light intensity on the optical axis is increased.

Title: Method and device for monitoring and controlling air ratio of burner in operation
Inventor: YAMAZAKI MASAKAZU
IPC: F23N5/08
Filed: 1988-03-25
Abstract: PURPOSE:To provide a control circuit having a high response characteristic and stability without being influenced by heat radiation of visible light and infra-red rays by a method wherein OH emission spectrum is detected in response to a linear relation between a strength of OH emission spectrum and an air ratio at a flame base part just after an outlet of a burner. CONSTITUTION:A light 17 emitted from a flame base part passes through a flame viewing hole 16, passes through a choper 21 and inputs into a spectroscope 22. Detected OH spectrum is photoelectrically converted by a photomultiplier 23. OH emission spectrum converted into an electrical signal is transmitted to a control part 3. A control unit 31 stores a constant of the fuel. The value of the OH emission spectrum strength corresponding to a desired target air ratio is set in reference to an input signal from a fuel flow meter 13. An air flow rate control valve 4 is controlled for its driving operation in such a way as the OH emission spectrum strength signal from the spectrum detection part 2 may coincide with this target value, thereby the most appropriate operating air ratio can always be kept.

IPC: H01R33/76
Filed: 1996-03-27
Abstract: PROBLEM TO BE SOLVED: To perform a sufficient wiping and reduce inductance by providing a guide part sliding with a contact member on a contact pin. SOLUTION: When an IC package P is inserted from above, and pressure of a cover 5 is released, each part of a contact pin 2, a contact member 3, and the cover 5 are returned to positions shown by the actual line, and the lead L of the IC package is nipped by the contact member 3 and a cap 4.

Title: Voltage detection circuit
Inventor: SAWAMURA HIROSHI
IPC: G01R19/00
Filed: 1993-03-08
Abstract: PURPOSE:To detect a high voltage with high accuracy by a method wherein one terminal of a voltage-holding circuit is connected to a ground terminal of a voltage detection circuit and a terminal voltage is maintained at a constant level. CONSTITUTION:A voltage-holding circuit 2 consists of a zener diode 21 and a resistor 22 and the value of the resistor 22 is so selected that the current flowing in the diode 21 permits the zener diode to have the most stable zener voltage when a current to be detected is applied to an input terminal 11a. Assuming that a zener voltage is Vz and detected voltage of a voltage detector 1 is Vd, a voltage of the ground terminal 16 of the detector 1 held by the circuit 2 is Vz. When an input voltage is higher than Vd+Vz, an output transistor 14 turns off and when the voltage is lower than that, it turns on. The detection error of the circuit is equal to the sum of an error of the detector 1 and the voltage Vz so that when selecting the diode having the stable voltage, the highly accurate detection of a voltage can be performed.

Abstract: PURPOSE:To attain high speed data transfer without incurring increase in a data storage circuit or requesting high processing speed of a host device by allowing two transfer means to execute separately the detection of presence of a fault of a reception frame and preparatory processing including a DMA transfer or the like. CONSTITUTION:In the case of receiving plural consecutive frames, two reception data control circuit sections 2, 3 apply DMA transfer of the reception data of a frame to a host device alternately for each frame. While one reception control circuit section 2 (3) receives a frame and applies DMA transfer of the frame to the host device, the host device discriminates it that no error takes place in the data of the frame received by other reception data control circuit section 3 (2). Then the setting of the address and length for DMA transfer control required for the reception of the succeeding frame and the execution of various control instructions required for flag synchronization are applied to the other reception data control circuit section 3 (2). Thus, the high speed data transfer is applied to the host device without incurring the increase in the data storage circuit and requesting a high speed processing to the host device.

CONSTITUTION:A light permeable conductive film, which is the first conductive film 2, is formed on the whole surface of a substrate with an insulating surface, for instance a glass substrate 1. Then a laser beam is applied to form the first open ditches 13 for scribe lines and the first electrodes 15 are formed in respective activation element regions 31 and 11. After that, a non-single crystal semiconductor 3 is formed over the whole surface. Further, the second open ditch 14 is formed over the left side of the first open ditch 13. High-intensity light with a wavelength of 500nm or longer is applied to the non-single crystal semiconductor to form an I-type semiconductor as a semiconductor with column shape grains whose grain direction is vertical to the substrate. At that time, the semiconductors of the passivation regions 34 and 33' in the ditch 13 are kept from annealing by a metal mask 50 to provide isolation between the first electrode of the element 31 and the first electrode of the element 11.

Abstract: PURPOSE: To improve the stability and heat transmissibility by specifying the structure of the gas sensitive member and the heater for the member.  
     CONSTITUTION: A gas bluk-shaped sensitive member 1 mainly composed of an oxide semiconductor such as SnO 2  and ZnO is joined on the heater 2 for the gas sensitive member as a bulk-shaped resistance element made up of a composite body of a conductive ceramics, a metal resistor, precious metal such as Ag, Pd and Pt and a heat resisting oxide such as Al 2 O 3  and ZrO 2  with a conductive adhesive 4 or the like including Ag, Pd and Pt. The heater 2 is energized with the lead wires 5' and 6' to heat the gas sensitive member 1. The change in the resistance of the member 1, caused when the combustion gas is absorbed by the gas sensitive member 1, is detected as the change in the resistance between the electrode 3 and the heaters 2 or 6. Thus, the gas detection is performed. This can uniformize and stabilize the joining of the heater 2 on the gas sensitive member 1 while minimizing the deterioration in the heater 2 thereby bettering the heat transmissibility to the gas sensitive member 1.
