Patent JP-S55133378-A (JP)
Title: Manufacture of 55bromm55nitroo1*33dioxane
Inventor: UERUNERU GERUHARUTO
IPC: C07D319/06
Filed: 1980-04-03
Abstract: 1. A process for the production of 5-bromo-5-nitro-1,3-dioxane by reacting 2-bromo-2-nitro-1,3-propane diol with formaldehyde or paraformaldehyde in an inert solvent at elevated temperature and in the presence of concentrated sulfuric acid, characterised in that tetrachloroethylene is used as the solvent.
Patent JP-S61202398-A (JP)
Title: Read-only semiconductor memory device capable of electrical writing
Inventor: HAMADA MITSUHIRO
IPC: H01L27/102
Filed: 1985-03-05
Abstract: PURPOSE:To secure a stable writing action by having a collector area connected to a power supply or another power supply having a constant voltage level higher than the first power supply between the collector areas of different cell groups and therefore inhibiting formation of a transient current path made by transient pnp and npn transistors in a writing mode. CONSTITUTION:A current 100mA is flowed to a word driver WD2 from a digit line D11 via a pnp transistor (TR) Q42 to short-circuit the junction of an EB diode D42. In such a case, the base and collector currents of the TR Q42 are equal to 56mA and 44mA respectively as long as beta of the TR Q42 is set at 0.8. While the emitter of an npn TR Q82 is set at 2V and the base can rise up to 4.4V. Thus the TR Q82 can be completely turned on and this means the subtraction of current from the collector. However this means that the current is just subtracted from a power supply VCC since the collector of the TR Q82 is connected to the power supply VCC. Thus it is avoided that the write current is partly led from the line D11 to cause a writing defect.

Title: Debug processing system for logic circuit
Inventor: HARA HIROTAKA
IPC: G06F17/50
Filed: 1985-03-05
Abstract: PURPOSE:To reduce the scale of a searching tree by comparing the value obtained by tracing different buses at the start point of convergence with the convergence information of a circuit, and discontinuing the searching with those discordant values. CONSTITUTION:A searching route selection part 24 produces a searching tree which traces a circuit back to the input side from the output side and selects successively the routes to be searched next. When an end point is decided by a convergence end point deciding part 25, a start point contancy checking part 26 is started to check the value related to a different bus going back to the start point. If the value related to a different bus has conflict, a searching cut-off part 27 is called out. The part 27 cuts branches of the searching tree to discontinue the searching action and proceeds to the next new search. Otherwise, the present searching is advanced by a searching advancing part 28.

Abstract: PROBLEM TO BE SOLVED: To prevent slipping-off of a back hanger by locking a deformation expansion projection in a deformation locking hole by performing rotation after the deformation expansion projection of the back hanger is inserted in the deformation locking hole of a wall panel. SOLUTION: A deformation locking hole is formed in the bottom face of a wall panel 1, and the deformation expansion projection 6 of a back hanger 3 is locked in the deformation locking hole.

When the back hanger 3 is rotated, the projection 6 is locked in the edge part of the deformation locking hole, furthermore, when it is rotated up to 90 degrees, a floor frame support part is parallel to the wall panel 1, and locking is performed completely. In this state, the floor frame support part of the back hanger 3 is supported on a floor frame 4 to attach the panel 1. Thus, in the case of attaching work of the wall panel, even if the wall panel is slid, fear for slipping-off can be lessened.
