Title: Feeding mechanism for resistance welding machine
Inventor: MATSUZAKI MINEO
IPC: B23K11/06
Filed: 1985-11-15
Abstract: PURPOSE:To facilitate the wire handling which pulls out a new electrode wire for welding the succeeding can be providing the stopper column which reaches the upper end to the low level by the prescribed distance than the lower end of the feeding plate in welding. CONSTITUTION:Stopper columns 6A, 6B checks the descent by colliding with the lower face of the feeding plate 2 when the plate 2 which is descended at the same time is descended by the distance (d), in case of an electrode roller 8 being descended from a can shell seam 11 at the welding completion time of the can shell seam 11. In this case the inner face of the right side flange part 42b of the feeding plate 2 is separated from the end face of a feeding rotor 1 with the feeding plate 2 being pushed up to the right upper part along the side wall of the recessed place at the upper end of the column 5A. The wire handling of pulling out the new electrode wire for welding the succeeding can is made easy by descending the electrode roller 8 at the completion time of the welding work and by separating the feeding plate 2 from the feeding rotor 1.

Title: Magnetic pefrigerator
Inventor: MATSUOKA FUMIO
IPC: F25B21/00
Filed: 1988-10-12
Abstract: PURPOSE:To enable the title device to be continuously operated while keeping a temperature level constant at all times by providing a magnetic action material which generates heat due to the increase of a magnetic field generated from a magnetic generator and absorbs heat due to the decrease of the magnetic field, providing a high-heat source and a low-heat source both of which exchange heat with the magnetic action material through respective heat pipes with a thermal switch, and packing high boiling-point refrigerant in the high-heat source and low boiling-point refrigerant in the low-heat source. CONSTITUTION:Heat which a magnetic action material 1 generates by the increase of a magnetic field is transferred to high boiling-point refrigerant 11 in a high-heat source 3 through a heat pipe 13 with a first thermal switch and is used as latent heat for gasification of the refrigerant 11. On the other hand, heat which the magnetic action material 1 absorbs due to the decrease of the magnetic field is absorbed from low boiling-point refrigerant 12 in a low-heat source 4 through a heat pipe 14 with a second thermal switch and is used as latent heat for liquefying the refrigerant 12. As a result, the temperature levels of both the high-heat source 3 and the low-heat source 4 are not fluctuated accompanying the operation of a refrigerator but always kept constant so that heat can be utilized for a continuous heating and cooling operation.

Title: Photosensitive semiconductor element, photosensitive semiconductor device, photosensitive circuit, and frame control method using photosensitive semiconductor element or photosensitive semiconductor device
Inventor: PAUCHARD ALEXANDRE
IPC: H01L31/10
Filed: 1999-09-10
Abstract: PROBLEM TO BE SOLVED: To provide a small and durable photosensitive semiconductor element or photosensitive semiconductor device with high selectivity, effectiveness, and detection capability. SOLUTION: The photosensitive semiconductor element comprises a substrate 1, an intermediate layer 2, and an external layer 5 while the intermediate layer 2 at least partially embedded in the substrate 1 and the external layer 5 in the intermediate layer 2. The intermediate layer 2 and external layer 5 form a photosensitive region 22, generating a light-dependent signal such as optical current. The external layer 5 is divided into regions 11 which, spaced apart from each other, are isolated by a region 13 of the intermediate layer 2. The spaced region 11 of the external layer is used, for example, as an anode of a photosensitive semiconductor element, connected to a detection circuit. Thanks to the region 11, re-coupling of a charge carrier reduces, preventing formation of an inactive layer. Thus, the optical current generated by incident light increases.

IPC: G03G15/10
Filed: 1989-09-30
Abstract: PURPOSE:To restrain the deterioration of fixation characteristic by dividing a developing tank to a 1st developing tank which is used at the time of ordinarily forming an image, a 2nd developing tank which is used for cleaning after finishing copying and a 3rd developing tank which is used for cleaning before starting copying and making the capacity of the 3rd liquid tank maximum. CONSTITUTION:Carrier liquid K3 in the 2nd developing tank 19 whose evaporation characteristic is low is mixed in carrier liquid K3 in the 3rd developing tank 20, which is mixed in developer K1 in the 1st developing tank 18. When the carrier liquid K2 in the 2nd developing tank 19 whose evaporation characteristic is low is mixed in the carrier liquid K2 in the 3rd developing tank 20 and the carrier liquid K3 is mixed in the developer K1, the carrier liquid K2 in the carrier liquid K3 is caused to be mixed in the developer K1. Since the evaporation characteristic of the carrier liquid K2 is low, the fixation characteristic is deteriorated. Then, the capacity of the 3rd developing tank 20 is made maximum, so that the rising rate of the concentration of the carrier liquid K2 in the carrier liquid K3 gets low and the deterioration of the fixation characteristic, as a result, is restrained for a long term.

Abstract: PURPOSE:To stabilize an operating characteristic by impressing a shutter pulse on a semiconductor substrate synchronously with a vertical transfer pulse, in a vertical blanking period. CONSTITUTION:A shutter pulse Ps (and Pstau) as an electronic shutter function is impressed on a semiconductor substrate 1 synchronously with vertical transfer pulses V1-V4 (and Vtau+1-Vtau+4).

However, the shutter pulse Ps(and Pstau) which sweeps a signal charge Q in a light receiving part 2 is impressed synchronously with the vertical transfer pulses V1-V4 (and Vtau+1-Vtau+4), so that the potential of the substrate surface can be stabilized by preventing the vertical transfer pulses V1-V4 (and Vtau+1-Vtau+4 from depending on the potential. And also, the shutter pulse Ps (and Pstau) is impressed in a vertical blanking period (VBLK).

For instance, only the picture elements of odd-numbered columns are processed in odd-numbered rows and only the picture elements of even-numbered columns are processed in even-numbered rows. The printer prints only the processed every other picture element.

Furthermore, synchronizing signals corresponding to cos 2 omegat=0 and sin 2 omegat=1 are guide from a synchronization oscillator 5 and applied to a sampling circuit 12. The component of sin 2 omegat is taken out. By the same way, cos 2 omegat and sin omegat are taken out with the synchronization signals of sin 2 omegat=0, cos 2 omegat=1 and cos omegat=0 and sin omegat=1. As a result, only the terms of S1/2, S2/2, S3 and S0 are taken out by specified expressions. The terms are outputted from the sampling circuits 11-13 and a low-pass filter 10.
