Title: Data holding system
Inventor: TAKAHASHI NOBUHARU
IPC: G09G5/26
Filed: 1989-07-25
Abstract: PURPOSE:To evade such a case that data which is already written is deleted and can not be used again and to improve the processing speed when an outline font is printed out by holding dot-format data which is generated only when specific size is specified on a nonvolatile memory. CONSTITUTION:It is decided whether or not the specific size, i.e. size which is used frequently is specified for the dot-format data which is generated by conversion from the outline font. When the specific size is specified, the dot- format data which is generated by the conversion is held on the nonvolatile memory and stored semipermanently. Consequently, the case wherein the data which is already written is deleted and can not be used again is evaded and the amount of data is reducible, so retrieval is facilitated and the processing speed when the outline font is printed out is increased.

Title: Semiconductor integrated circuit
Inventor: YAMADA MICHIHIRO
IPC: G11C11/407
Filed: 1983-10-13
Abstract: PURPOSE:To hold a boosted level for a long period by providing a charge pump circuit to an output circuit which generates an output signal boosted above a source voltage. CONSTITUTION:MOS Transistors (TR) 5, 6, 7, and 8 and a capacitor 9 for a charge pump constitute the charge pump circuit 12. The output signal PHIB is boosted above the source voltage VCC at time t4. For example, the level ''H'' of the output signal PHIB decreases slightly owing to a leak current at time t6 after a long time is elapsed. Then when a clock signal PHIC from an oscillator 4 rises at time t7 from the level ''L'' to the level ''H'', the level at a node 11 is boosted above VCC+VTH by the capacity coupling of the capacitor 9 for the charge pump and the MOSTR8 turns on to supply a charge from the capacitor 9 to the output signal PHIB. Therefore, the level ''H'' of the output signal PHIB recovers at the time t7.

Filed: 1998-07-09
Abstract: PROBLEM TO BE SOLVED: To provide a method for forming microlenses, having a step for achieving hydrophilicity by eliminating a hydrophobic deposited film formed on each of the microlenses at total dry etching. SOLUTION: In a method for forming microlenses, a resist film 4 on a lens material film 3 is patterned, in such a way that each microlens forming area is separated individually. Each of the resist films 4 is formed in the shape of a convex lens through heat melting. The resist films 4 and the lens material film 3 are etched back by total dry etching with a mixture of oxygen and a as exhibiting depositability for transferring the form of convex lenses to the lens material film 3. In this case, a hydrophobic deposited film 8 is formed on the surface of the microlenses 7 by the total dry etching with the mixture of oxygen and the gas exhibiting depositability.  The hydrophobic deposited film 8 sheds water during later operation of wafer dicing and eliminates the possibility of defective pixels after assembly due to chippings of silicon or the like which may remain on the surface if they are not washed down. Then after this operation of transfer, there is a step for obtaining hydrophilicity, by eliminating the hydrophobic deposited film 8 on the surface of the microlenses 7 by oxygen plasma treatment.

Abstract: PURPOSE:To enhance the responsiveness of a check valve by providing a magnetically urging means for urging a valve element movably disposed in a valve chamber and made of magnetic materials in a direction in which it closes a through-hole in a valve seat. CONSTITUTION:A valve seat 7 formed therein with a through-hole 16 is provided in a large diameter section 15 on the upstream side of the latter, and a valve element 22 made of magnetic materials is disposed in a valve chamber 21 between a partition wall and the valve element 17. A magnetic coil 23 as a magnetically urging means is wound on the outer peripheral surface of the large diameter section 15 of the valve body 11. When a differential pressure larger than a magnetic force by which the coil 23 attracts the valve element 22 is effected between the upstream and downstream sides of the valve seat 17 in a valve closing condition, the valve element 22 is lifted from the valve seat 17. Accordingly, even though the differential pressure does not vary greatly, the valve element 22 can fully open the through-hole 16, thereby it is possible to enhance the responsiveness of the check valve for the differential pressure.
