Title: Column for liquid chromatography
Inventor: MIYATA SHINJI
IPC: G01N30/60
Filed: 1989-04-10
Abstract: PURPOSE:To achieve a high density packing of a filler by dividing a hood in two - liquid inlet and outlet sides. CONSTITUTION:For the purpose of packing a filler, an inner cylinder 1 is placed at an end fitting 7 on the liquid outlet side where a liquid outlet side filter 4 and a gasket 5 are fitted and a flange part is pressed with a liquid outlet side hood 12b to screw down the fitting 7. Then, the inner cylinder 1 is fixed. Then, a packer is screwed down on a male screw of the hood 12b to pack a slurry packing material. In the column as the packer is removed, the inner cylinder 1 is extruded outside the hood 12b and the packing material swells at the top of the inner cylinder 1. Therefore, the inner cylinder 1 is fixed on the fitting 7 with the hood 12b and in the removal of the packer, the inner cylinder 1 will not move to be taken off the hood. This enables high density packing with easier work of shaping of the surface of a packing material into a mound.

Title: Bridge type converter protection apparatus
Inventor: OKATSUCHI CHIHIRO
IPC: H02M7/48
Filed: 1991-04-19
Abstract: PURPOSE:To safely cut off an over current by connecting in series a P-channel IGBT and an N-channel IGBT which ensures wider safe operation area than such P-channel IGBT and turning off the gates, if an over current is detected, of both P-channel IGBT and N-channel IGBT after limiting the over current with the N-channel IGBT. CONSTITUTION:Upon reception of an over current detecting signal el7, a gate control circuit 32 executes gate squeezing operation of N-channel IGBT (N) 22, 24, 26. Therefore, a current I is limited. During this period, a gate voltage is normally applied to the P-channel IGBT (P) 27, 28, 29. Accordingly, P27, 28, 29 are not deteriorated. Thereafter, a time delay circuit 31 outputs a signal e31, the gate voltages of N22, 24, 26 and P27, 28, 29 turn off and each element turns off to cut off an accident current. Thereby, since the current I is limited, P27, 28, 29 safely turn off.

Filed: 1990-04-04
Abstract: PURPOSE:To prevent a picture from being deformed at rewrite of a picture data or the like by providing plural memories and a comparison means comparing a memory number of the plural picture memories with a memory number of a picture memory accessed at present. CONSTITUTION:A memory control section 21 compares a memory number of a picture memory designated from a sender side with a memory number of a picture memory accessed at present. When it is discriminated that they are coincident, the memory number designated from the sender side is revised according to the memory number stored in a storage means and the received picture data is stored in frame memories 14-16 of the revised number. Thus, a unsightly pattern such as deformed picture is not displayed at rewrite of the picture data.

Title: Heating device for bonding lamination steel plate
Inventor: IWASAKI YUKIHIRO
IPC: H02K1/18
Filed: 1994-04-26
Abstract: PURPOSE:To heat a steel plate with high accuracy by simple equipment by performing the induction heating of a steel plate only during a heating period of time which is automatically set on the basis of a temperature before heating the lamination steel plate. CONSTITUTION:The control part 34 is provided with a frequency control means 90 for setting the frequency of an induction heating means 32 and a heating time controlling means 92 for setting a heating time, and at the same time a radiation thermometer (temperature detecting means) 94 disposed within a firing base 36 for detecting a temperature before heating a laminated steel plate 18 is connected to the control part 34. When a frequency becomes low, the uniform distribution of the heating temperature of the steel plate 18 is made better and however, the heating time is made longer to make a heating cycle time longer. On the other hand, when a frequency becomes high, the heating time is made shorter and however, the uniform distribution of the heating temperature of the steel plate 18 is made worse. Therefore, in order to obtain the uniform distribution of a temperature by heating in a relatively short time, the applicable frequency may be set within the range of 10Hz to 100Hz.

Title: Binarizing processing unit
Inventor: OGAWA NOBUO
IPC: G06T5/00
Filed: 1992-04-09
Abstract: PURPOSE:To separate a binarizing area and an intermediate area regardless of a line width of a line pattern by taking presence of an edge and a density gradient history into account so as to discriminate whether or not each picture element is to be binarized. CONSTITUTION:Gradient history information obtained by a gradient discrimination means 112 is stored in a history storage means 113. A discrimination means 114 discriminates whether or not a relevant picture element is a binary picture based on the history information and the result of detection by an edge detection means 111, and gives an instruction to a binarizing processing means 101 accordingly. The storage means 113 stores the gradient history information from the density increase gradient discrimination to the density decrease gradient discrimination. Moreover, while the said history information is stored and the detection means 111 detects an edge, the discrimination means 114 discriminates the said picture element to be the binary picture. In this case, the part between both edges of a linear pattern forming a character or a line drawing is discriminated to be the binary picture based on the storage history information. Thus, a binary picture area and an intermediate area are separated regardless of the line width of the line pattern.
