Title: Liquid crystal display device
Inventor: TAJIMA HISAO
IPC: G02F1/1333
Filed: 1990-08-27
Abstract: PURPOSE:To prevent the deterioration in the orientation of a liquid crystal by falling impact and oscillation while utilizing an air damper effect and to prevent the disconnection of circuits by forming one face side of a unit constituting a liquid crystal panel and the peripheral circuits as an approximately hermetic space, supporting this unit to a panel fixing plate and constituting the device pendent via an elastic member. CONSTITUTION:A liquid crystal panel 100 approaches a back light 107 when this panel receives the falling impact in a +z direction. The bending deformation of the elastic member 115 supporting the panel fixing plate 112 pendent increases at this time and further, an approximately hermetic space 118 is constituted by a supporting member 114 and a back light frame member 116 and, therefore, the displacement quantity of the plate 112 and the panel 100 is suppressed and the deterioration of the image quality by a change in the orientability of the liquid crystal is prevented. The panel 100 is adhered by an adhesive 113 to the plate 112 and further, the circuit board 111 is fixed to the plate 112. The panel 100 is, therefore, displaced in the back light 107 direction but since the circuit board 111 follows up this movement as well, the stress acting on a printed wiring film 110 is sufficiently small and does not lead to the breakage of patterns.

Title: Overcurrent protective system
Inventor: WASHIO TOSHIFUMI
IPC: H02H9/02
Filed: 1988-09-09
Abstract: PURPOSE:To lower rated values of components and to reduce the cost and size by lowering the load voltage when the load current increases over steady current and interrupting the circuit when the maximum load current continues for a predetermined time. CONSTITUTION:A transistor Q is turned ON/OFF by means of switching pulses fed from a pulse width control section 1 so that power fed from a DC power source V is converted into AC power which is then fed to a transformer T and thereafter it is rectified and fed to a load. Primary current of the transformer T is detected through current transformers CT0, CT1. A load voltage lowering means 2 receives the output from the current transformer CT0 and provides a signal to the pulse width control section 1 so that the output voltage is lowered when the current exceeds over a steady level and lowest regular voltage is obtained for the maximum rate current. A switching pulse block means 3 receives output from the current transformer CT1 and blocks switching pulses fed from the pulse width control section 1 when the maximum rated current flows for a predetermined time.

Title: Treatment of chromium-containing discharged water
Inventor: KATO ISAMU
IPC: C02F1/70
Filed: 1993-09-13
Abstract: PURPOSE:To enhance the concn. of obtained sludge and to reduce sludge treatment cost in a method wherein a ferrous ion is added to hexavalent chromium- containing discharged water to reduce hexavalent chromium to trivalent chromium and alkali is added to the treated water to separate trivalent chromium as insoluble hydroxide. CONSTITUTION:A part of the sludge separated in a sludge separation process 4 is introduced into a reducing process 2. By this method, hydroxide such as Fe(OH)3 or Cr(OH)3 is precipitated on the surface of the sludge returned to the reducing process from the sludge separating process 4. Since hydroxide precipitated on the surface of the return sludge becomes a two-dimensional structure, the free water in the sludge is reduced and the concn. of the obtained sludge increases. The concn. of the obtained sludge can be enhanced to a large extent as compared with a conventional method by extremely simple operation. The generation amt. of a dehydrated cake can be reduced to a large extent.
