Title: Bipolar-type semiconductor device
Inventor: KURAISON TORONNAMUCHIYAI
IPC: H01L29/78
Filed: 1993-12-27
Abstract: PURPOSE:To increase a switching speed and reduce a switching loss by a method wherein a porous region in which minority carriers are recombined is formed around an active region with a required spacing. CONSTITUTION:A porous region 7 which reaches the end 6 part of a chip is formed around an active region 10 with a required spacing La. With this construction, a depletion layer is extended as shown by a broken line at the time of the reverse bias of a diode but, as the required spacing La exists, a leakage current is not increased. At the time of the forward bias of the diode, minority carriers are injected into an N-type region 2 through a P-N junction 4. The minority carriers which are diffused in the N-type region 2 and reach the porous region 7 vanish by recombination and the minority carriers accumulated in the part of the N-type region 2 between the active region 10 and the end 6 of the chip are reduced. Therefore, when the diode is switched from the forward bias to the reverse bias, a reverse recovery time is reduced, so that a switching speed is increased and, further, a switching loss is reduced.

Title: History device
Inventor: KIMURA TOSHIO
IPC: G06F11/34
Filed: 1988-12-26
Abstract: PURPOSE:To facilitate the analysis of a fault by performing the comparison between the change pattern of each sequence and the pattern obtained by tracing the control signal of an input/output interface, holding the code corresponding to the relevant sequence as the history information when the coincidence of a comparison is obtained, and holding the trace information as the fault information when no coincidence of comparison is obtained. CONSTITUTION:The expected value is read out of an expected value memory 7 with the address set at a selector 4. This expected value is compared with the value of the control signal of an input/output interface traced by a trace register 9 via a comparing part 10 only when the value of the control signal is changed. When the coincidence of comparison is obtained, the several high- order bits of the address of the memory 7 held by the register 5 are successively stored in a sequence code memory 8 as a unique code showing the relevant sequence. In the case on coincidence of comparison is obtained, the value of the register 5 obtained when the no coincidence of comparison is detected and the value of the register 9 are stored in a fault register 11. As a result, the information of the fault is coded and the analysis of the fault is facilitated.

Title: Transilluminator for observing electrophoretic gel
Inventor: OKAMOTO HISASHI
IPC: G02B5/22
Filed: 1993-12-27
Abstract: PURPOSE:To eliminate the need of protection against ultraviolet rays by irradiating an absorbing filter, which can transmit the visible light in the exciting wavelength range of a visible light exciting fluorescent dye, with a visible light at a specified incident angle and then irradiating an electrophoretic gel, subjected to dyeing with a visible light exciting fluorescent dye, with a visible light of predetermined wavelength passed through the filter. CONSTITUTION:Light from a visible light source 1 passes through a condenser lens 4, a heat absorbing filter 7, and an ND filter 5 and then reflected on a mirror 6 to enter into an exciting filter 2 at an incident angle of about 90+ or -20 deg.. The filter 2 passes a light in such wavelength region as exciting the visible light exciting fluorescent dye without lapping over the wavelength region for fluorescent observation. When the light impinges on an electrophoretic get placed on the cover glass for the filter 2, the visible light exciting fluorescent dye which has dyed the nucleic acid in the gel is excited. The nucleic acid is detected by observing and measuring the fluorescence. This constitution eliminates adverse effect on the human body because ultraviolet rays are not employed in the measurement.

Abstract: PURPOSE:To simplify the structure by supporting the undriven-side end part of a magnet shaft rotatably on the undriven-side wall of a developing tank through a tank bearing while the end part penetrates the flange in the undriven side. CONSTITUTION:The undriven-side end part 22b of the magnet shaft 22 penetrates the flange 16 in the undriven side and is supported rotatably on the undriven-side tank wall 24 of the developing tank 11 through the tank bearing 25.

A driving force is transmitted directly to the magnet shaft 22 from outside and a magnet body 13 which is fixed on the magnet shaft 22 rotates to change its magnetic pole position. The undriven- side end part 22b of the magnet shaft 22 is borne by the tank wall 24 of the developing tank 11, so both bodies of rotation, i.e. the sleeve 14 and magnet body 13 are supported by one magnet shaft 22 running through a flange bearing 21 and the tank bearing 25. Consequently, the structure is simplified.
