Title: Shearing machine for wire rod bundle
Inventor: FUNAHASHI MUNEO
IPC: B23D23/00
Filed: 1983-08-25
Abstract: PURPOSE:To undo a bundle simultaneously with shearing, and to cut exactly a wire rod to pieces by inclining a cutting edge with respect to an axis of the wire rod, and also forming stepwise a step difference along the cutting edge, on the surface opposed to a wire rod bundle of at least one edge. CONSTITUTION:A wire rod bundle 1 of a wire rod 1a bundled by a grid band 2 is fed out in the direction A, the wire rod bundle 1 is pressed firmly against a receiving base 5 by a holding plate 6 and fixed, and thereafter, a moving edge 4 is moved in the direction C and brought to reciprocating driving in the direction roughly vertical to the axis of the wire rod 1a so as to pass each other with respect to a fixed edge 3, and the wire rod bundle 1 is shorn. In this case, the band 2 is cut diagonally by inclining a cutting edge of the edges 3, 4 with respect to the axis of the wire rod 1a, and also the wire rod bundle 1 is shorn to pieces by a step difference 4a formed stepwise along the cutting edge, on the surface opposed to the wire rod bundle 1 of the edge 4. In this way, a bundle of the wire rod can be uncoupled effectively at the same time as shearing of the wire rod.

Title: Output terminal equipment of multiplex transmission remote controller
Inventor: HISAMATSU NOBUO
IPC: H04Q9/16
Filed: 1984-07-25
Abstract: PURPOSE:To reduce the load of software by attaining a 1-shot action of a latching relay just through transmission of the control data on an ON state performed by a control controller. CONSTITUTION:When a control circuit 5 of an output terminal equipment fetches control data from a central controller, an output of H is produced from a control output terminal RD1. Then an output of H is also produced from a control output terminal RD5. Then a relay drive output is produced from a DRD terminal for a fixed period of time. Thus an H level is produced from an AND circuit A1. Then the circuit A1 turns on a transistor TRT1 to flow an energizing current to a set coil 5 of a latching relay RY and securs a setting action of the RY. At the same time, an FF8 is set and an output Q' is set at an L level. Then a counter C is actuated. An output Q1 is set at an H level by counting the first clock, and a TRT2 is turned on to flow an energizing current to a reset coil R of the relay RY. Thus the RY is reset to its original state for the 1-shot action of the RY. An output Q2 of a counter C resets the FF with the next clock. Then the counter C is put again under a reset mode.

Abstract: PURPOSE:To obtain a semiconductor light emitting device having a simple arrangement and a long lifetime, by depositing a diffusion preventing film in such a manner that the film is relatively thin at the side surfaces of a stripe part of an active layer but relatively thick at the other part, and diffusing an impurity only into the side surfaces of the stripe part. CONSTITUTION:At InGaAsP active layer 2, a P-type InP clad layer 3, a P-type InGaAsP electrode contact layer 4 are successively epitaxially grown on an N-type InP substrate 1. An etching mask 5 is formed to carry out inverted mesa etching and, subsequently, a diffusion mask is deposited using a plasma CVD apparatus. When an Si3N4 film 6 is deposited to a thickness of about 2,000Angstrom , since the deposition rate is anisotropic, the film 6 is relatively thin, i.e., about 100Angstrom , only at and near the side surfaces of the active layer 2. When, in this state, Zn is diffused, Zn is diffused only into thin parts 7 of the Si3N4 film 6. Thereafter, the diffusion mask 6 is removed, and a P-type InP buried layer 8 and an N-type InP buried layer 9 are grown and then electrodes 10 and 11 are formed to complete a laser diode having a buried double hetero-structure.

Title: Combustion control method based on concentration of o2 and co in combustion waste gas
Inventor: NISHIYAMA TETSUJI
IPC: F23N5/00
Filed: 1978-12-15
Abstract: PURPOSE:To prevent combustion with excessive air or incomplete combustion by controlling the feed rate of air for combustion on the basis of the concentration of CO when CO is found in the waste gas, and on the basis of O2 when CO is not found in the waste gas. CONSTITUTION:Since CO rarely occurs in an ordinary combustion in a combustion furnace 4, a signal representative of the concentration of O2 from an O2 meter 5 in a waste gas pipe 3 is input into a deviation detector 10 via a regulator 9. In the detector 10, the mentioned signal is compared with a signal representative of an object concentration of O2 to compute a deviation. A signal representative of the deviation is converted to a signal representative of flow rate of air in a conventer 11 by using a predetermined conversion factor with respect to deviation in O2 concentration and flow rate of air. With a signal from the converter 11, a control valve 8 for controlling the feed rate of air for combustion is operated. When abnormal combustion or combustion with a low concentration of O2 takes place, the concentration of CO is detected by a CO meter 6. Then, a switch 13 is shifted to a contact b by an output from a CO generation detector 12, and an output from the detector 12 is given to the control valve 8 through an air converter 14 to control the valve 8.

Filed: 1999-06-02
Abstract: PROBLEM TO BE SOLVED: To provide a protecting case for a connector capable of surely protecting connected connector from foreign object. SOLUTION: A connected connector is accommodated in an area αformed by a housing 41. A projecting part is fitted to a recessed part at a seal part 45 when the housing 41 closes.

A rib 44a becomes ring-like shape when the housing 41 closes. A part of a cable extending from each connector is fastened from all directions (namely, circumferential direction). Each rib 44a prevents invasion of foreign object from a through hole β by this fastening. In other words, foreign object can not invade into the area α along the axial direction of the cable by action of each rib 44a.

Abstract: PURPOSE:To provide stable oscillation and wide frequency variable width even when the resonator of a narrow induced band is used by connecting both the poles of an SAW (surface acoustic wave) resonator through a circuit provided with a parallel circuit composed of a variable capacitor and a coil. CONSTITUTION:A parallel resonance circuit is constituted by connecting a coil 15 to a VCO(voltage controlled oscillator) 10' parallelly to a variable capacity diode 12. Both the poles of an SAW resonator 11 are connected through this parallel resonance circuit. Thus, the VCO is operated preferentially for oscillation, the band showing inductivity is widened, and stable oscillation not affected by distributed capacity can be provided. Namely, the induced band of the resonator 11 is widened by connecting the coil 15, and the inductance of the parallel circuit is enlarged at a frequency lower than a parallel resonance frequency. In this case, when the resonance frequency is changed by the variable capacitor, the inductance is changed, and the induced band of the resonator 11 can be varied. Further, when the resonance frequency of the parallel circuit is made close to the oscillation frequency, a big inductance change can be provided by a small capacity change.
