Title: Protection system for memory contents
Inventor: OKAMURA KOUSUKE
IPC: G06F11/00
Filed: 1981-04-17
Abstract: PURPOSE:To prevent the contents of a specific memory from being modified in case of the runaway of a central processing part due to an intermittent fault, by controlling writing to a memory through the central processing part on the basis of an external control signal. CONSTITUTION:A flip-flop 9 is normally in a reset state, and set under the control of a peripheral equipment only for the modification or editing of a user's program, so that an address specifying part 4 attains writing address to a memory part 5 for the first time. While the flip-flop 9 is set, an arithmetic processing control part 1 controls the address specifying part 4 under the control of a system program regarding the modification or editing in response to a write request from the peripheral equipment through a peripheral-equipment control part 8. Consequently, while reading operation is performed upon occasion, memory access to desired addresses for writing is performed to modify or edit the contents of the memory part 5, namely, the user's program as desired.

Title: Quenched tempered glass container
Inventor: KATOU TAKETOSHI
IPC: C03B27/06
Filed: 1980-04-30
Abstract: PURPOSE: A quenched tempered glass container, having stable practical strengths, and prepared by molding a glass container having a specified wall thickness range on the body part thereof, quenching and tempering the molded material, and forming a layer of higher compression stress on the inner surface of the body part than that of the outer surface.  
     CONSTITUTION: A glass container is molded to give an average glass wall thickness value (X) in the body part of 1.7W3.8mm, the maximum glass wall thickness value in the range expressed by formula I and the minimum glass wall thickness value in the range expressed by formula II. The resultant molded glass container is then quenched in a temperature range of about 0W150°C below the deformation point of the glass at a cooling rate of about 20W30°C/sec by adjusting the velocity of a fluid, e.g. air. Thus, a compression stress layer on the outer surface and a compression stress layer having a higher stress value on the inner surface than that of the outer surface thus formed provide improved practical strengths such as improved scuff resistance, synergistically enhanced internal pressure strength and impact strength in the quenched tempered glass container.

Title: Drop on demand ink jet head
Inventor: SHIODA TOYOJI
IPC: B41J2/055
Filed: 1987-03-11
Abstract: PURPOSE:To make the injecting direction of ink drop uniform and to prevent occurrence of foam, by projecting the end face of a head containing rows of nozzles formed with accumulated nozzles from the head body and making the width of projecting face at most about two times of the cross-section of each nozzle and symmetrical with respect to the nozzle rows. CONSTITUTION:The surface containing nozzles 21 projects by a width of (b1+b2+b3) to form a projecting face 10, where b1, b3 are shorter than half of the nozzle width b2. When a head is driven, the end face is wetted by ink, but since a projecting section 11 has a narrow width, ink adhered to the projecting section 11 forms a thin film and excessive ink flows into a recess 12. The end face is formed from hydrophylic material in order to promote dispersion of ink. When an ink drop is injected, surface tension is balanced between an ink drop 27 and ink around the nozzle 21 if the projection 11 is symmetrical with respect to the nozzle 21, thereby injecting direction of ink drop is made uniform thus retarding entrapment of foam into the nozzle.

IPC: G09F9/00
Filed: 1978-05-17
Abstract: PURPOSE: To produce the elements of superior characteristics and appearance with good yield by using low melting point glass frit paste.  
     CONSTITUTION: After low melting point glass frit paste 8 is coated in the specified positions in one or both of upper and lower glass substrates 1, 2, the substrates are individually subjected to primary firing to preglaze the frit paste 8 to vitrified sealing material 9. After this, the upper and lower glass substrates 1, 2 are superposed and are then subjected to secondary firing. This causes the solvent and binder in the frit paste 8 to decompose and fly off into the atmosphere during the primary firing, thereby forming the vitrified glass sealing material 9 free from bubbles. In addition, the frit paste 8 may be readily and accurately coated in the specified sealing position and therefore the upper and lower glass substrates 1, 2 are accurately and surely sealed.

The dispersion so obtained is mixed with an aqueous solution containing an emulsifying agent and the mixture is homogenized. Polymerization is then effected to form a magnetic-polymer latex containing hydrophobic vinyl aromatic polymer particle. More organic monomer component may be added immediately prior to or during polymerization. Alternatively, the magnetically-charged material may be dispersed into an organic phase comprising an organically soluble initiator and a water-soluble organic compound. An organic monomeric component is added to the aqueous-organic phase mixture after homogenization and prior to or during polymerization, which is effected to form a magnetic-polymer latex containing hydrophobic polymer particles. The magnetic-polymer latices obtained are useful in paints, magnetic tapes, recordings, and biological applications.
