Title: Electromagnetic drive shutter
Inventor: HIROHATA MICHIROU
IPC: G03B7/087
Filed: 1980-02-08
Abstract: PURPOSE:To prevent an exposure error due to the bounding of a shutter, influences of variation in exposure due to time lag, etc., by specifying the opening characteristics of a subordinate aperture. CONSTITUTION:Through shutter release operation, an electric current is supplied and a rotor rotates counterclockwise to slide shutter blades 8... in their opening directions. Prior to the shutter opening of blades 8..., a subordinate aperture starts openings by subordinate blade window 8a of blades 8 and mask part 22a of subordinate blade 22. Consequently, the exposure is corrected and an exposure error due to the time lag of shutter closing operation after the generation of a shutter closing signal is prevented. Next, the shutter which is to open closes the subordinate aperture again through blades 8 corresponding to the time of bound occurrence and no shutter closing signal is generated; and the shutter closing signal is generated when the subordinate aperture is opened to half during fully opening operation of the shutter, so that influences of variation in exposure due to the bounding of the shutter will be prevented.

CONSTITUTION:A necessary word voltage VCH is applied to a row wire PS1 to correspond to a B1.1 and a voltage 0V is applied to a column wire phiB1 to correspond to the B1.1. A block selecting P-MOS transistor Q1.1 is turned-ON and a feeder P1.1 belonging to the B1.1 is charged with a voltage Vch. A gate voltage of a P-MOS transistor constituting a word driver belonging to the B1.1 is definite and the Vch is charged in a selected word line. After the P1.1 is applied the voltage only for a desired period, it is discharged in the 0V through an N-MOS transistor being connected to it. As a feeder of a non- selection block is always actuated in the 0V, a subthreshold current is not made to flow through the word driver in the non-selection block. Accordingly, the whole through current is significantly decreased to one piece of a through current only in roughly a selection block.

Filed: 1991-01-14
Abstract: PURPOSE:To generate enlarged characters, etc., with stroke width of the same ratio with dot enlargement by changing calculation expressions for node coordinates according to the direction of a vector and adjusting the stroke width of characters or a figure after enlargement. CONSTITUTION:A character code and an enlarged character size are inputted from a keyboard 7. A CPU 3 reads vector data corresponding to the character code out of a dictionary 2 and writes it in a memory 4. The CPU 3 performs a magnification varying process for enlarging each vector data to the specified size. In this magnification varying process, node coordinates are calculated from 'nX(Bi+1)-1' when the vector is so directed that X>=0 and Y<=0, or X<=0 and Y<=0. When the vector is in the opposite direction, the node coordinates are calculated from 'nXBi'. Here, (n) is a magnification rate, Bi coordinate values of the vector, X the left direction of the vector, and Y the downward direction of the vector. The enlarged character based upon said values has a dot deficiency eliminated in the right direction and downward direction.

Title: Glass bonding method for magnetic head
Inventor: ONISHI KAZUMASA
IPC: G11B5/60
Filed: 1986-01-28
Abstract: PURPOSE:To prevent very effectively the occurrence of air bubbles in a glass by performing glass bonding in the pressured atmosphere of inert gas. CONSTITUTION:Pressured inert gas (like N2) from an inert gas bomb 21 is supplied to a closed vessel 20 directly, namely, without passing the pressure reduction process. If pressure is deficient when gas is supplied merely from the gas bomb 21, gas is pressured by a pressure pump 22. When an assembly A is heated by a heater 23 simultaneously with this introduction of pressured inert gas, a fused glass rod 15a enters into a gap G between a magnetic core 11 and a magnetic head inserting groove 14 and grooves 11d on the surface of the magnetic core 11 to perform glass bonding. Thus, air bubbles included in the fused glass are not expanded, and especially, they appear scarcely appear on the surface of the glass.

Abstract: PURPOSE:To prevent the destruction of another program due to only one bug of a processing program, by adding a protecting circuit having a process register and a time managing circuit to a central processing unit. CONSTITUTION:For example, while a processing program A is processed by a central processing unit (CPU) 1, a protecting circuit 6 monitors whether storage areas other than those assigned to the processed program A are processed by the CPU or not. If it is detected that said storage areas are processed, an interrupt signal 10 is sent to the CPU1. Then, the CPU1 judges the processing program A to have a bug and interrupts the processing and performs a corresponding countermeasure processing. This processing time is controlled and managed by a time managing circuit 5; and when the processing request of a processing program B is generated newly, a new number is assigned to the program B when the program is returned to a control program, and the processing is executed similarly to the program A. The protecting circuit 6 monitors storage areas other than those assigned to the program B at this time also.
