Title: Determining method for rust-proofing degree in steel ground processing
Inventor: TAKAHASHI HIROTAKA
IPC: G01N21/57
Filed: 1980-04-25
Abstract: PURPOSE:To objectively and quantatively determine and evaluate a rust-proofing degree, by a method wherein a gloss retention rate of a rustproof-treated surface is measured from correlation between the rust-proofing degree and the gloss retention rate. CONSTITUTION:In an unprotected steel material, the steel plate whose whole surface is rusted, the steel plate which is simply derusted by means of a wire brush, the steel plate which is enoughly derusted by means of a power brush and a disc sander, the steel plate applied with wash primer as shop primer, and an epoxyzinc primer coated steel plate are prepared. A plate, which is rusted under a condition to be exposed to the outdoors, and a plate, which is processed in a manner described in the unprotected steel material, are used as a material to be tested, and a gloss retention rate, which is obtained from a 60 deg. mirror surface reflection of each processed surface, is measured. As a result, it is found that, with the improvement of the rust-proofing degree, the gloss retention rate increases. The optical measurement of the rust-proofing degree in a manner described above reduces influence produced due to an individual difference and also permits the simple determination and evaluation.

Title: Phase confirming circuit for power supply in combustion control system
Inventor: ITSUSHIKI RIYUUKOU
IPC: G01R31/02
Filed: 1981-04-13
Abstract: PURPOSE:To prevent accident of explosion or the like resulting from erroneous wiring connection of grounding phase of the power supply circuit to a control box by a method wherein power can be supplied to a control circuit only when polarity of both the power supply and control circuits is matched. CONSTITUTION:A relay X to confirm abnormality is provided between an earth line 3 and a grounding point E in the subject circuit located between the hot line 2 and earth line 3 in which a combustion solenoid valve SV, an ignition transformer IGT and the control circuit 1 for the above are provided.

In addition, a pair of b-contact Xb of the relay X is provided on the earth line 3 at a point beyond the abnormality indicator lamp RL but no farther than the control circuit 1. This feature allows application of voltage on the relay X to open the pair of contacts Xb when grounding phase of the power supply circuit is erroneously applied to the R- phase, thereby power supply to the control circuit 1 can be impeded. Simultaneuosly, the abnormality indicator lamp RL is lighted to inform erromeous  wiring by closing the pair of contacts Xa.

Title: Dust preventive breathing protector
Inventor: IIO TOSHIAKI
IPC: A61F9/06
Filed: 1988-03-11
Abstract: PURPOSE:To widen the visibility of a worker as well as to contrive an improvement in workability by pivotally mounting a face cover onto a helmet, covering the face cover with colored but transparent glare protection lenses at its front and side surfaces, mounting a welding plate in such a way as to be freely opened and/or closed, and thereby connecting an electric fan in order to supply positive pressure inside. CONSTITUTION:During operations under dust environment, for example, TIG welding operations, when a worker puts a helmet 1 on his head with its face cover 2 lowered, with its welding plate 16 closed and with an electric fan 7 driven, compressed air is blown off between the face cover 2 and his face out of the blow-out port 11 of a pipe section 2a via an air hose 5 so that the space can be maintained at normal pressure. The worker therefore will never breath dust at all, he can thereby keep up the work while making sure of section to be welded through the welding plate 16. And when it is required to make sure of the finish of welding with welding works suspended, the finish can be confirmed through a glare protection lens 13 with a window frame 13b opened upward. Since a part of the colored but transparent glare protection lens 13 is exposed on each of the both sides of the face cover 2, the visibility of the worker is widened, workability is thereby improved.

Filed: 1993-03-17
Abstract: PURPOSE:To allow introduction of strain to a GaAs layer in aGaP-GaAs hetero superlattice by forming a quantum well of a GaP barrier layer and a GaAs well layer in an Si substrate. CONSTITUTION:A quantum well, i.e., a GaP-GaAs hetero superlattice 3, comprising a GaP barrier layer 3B and a GaAs well layer 3A is formed in an Si substrate 1. When a strain is applied to the GaP-GaAs hetero superlattice 3, the GaAs well layer 3A is subjected to strong compressive strain whereas the GaP barrier layer 3B is subjected to weak compressive strain.

Title: Collision deciding device
Inventor: SUZUKI HIROAKI
IPC: B60R21/16
Filed: 1992-02-10
Abstract: PURPOSE:To provide a collision deciding device whereby collision can be decided by a single G sensor. CONSTITUTION:In an output signal (a) of a G sensor mounted onto a vehicle, a frequency is analyzed by a Fourier frequency analytic part 2. A collision mode decision part 3 decides a collision mode based on a feature of this frequency analysis. A DELTAV threshold value setting part 4 sets a DELTAV threshold value alpha0 matched with the collision mode. On the other hand, a G signal integrating part 5 integrates the signal (a) processed. This integrated value DELTAV is compared with the DELTAV threshold value alpha0 in a collision deciding part 6. When the integrated value DELTAV is increased larger than the DELTAV threshold value alpha0, the collision deciding part 6 outputs a collision signal. When the collision signal is output, a squib starting part 7 is started to inflate an air bag not shown. Since a DELTAV threshold value alpha0 matched with the collision mode is set, collision can be decided by a single G sensor.
