Title: Power consumption reducing apparatus of electronic device
Inventor: SERUBERU MISHIERU
IPC: H04B1/16
Filed: 1989-04-14
Abstract: PURPOSE: To prevent any useless or power consuming level transition from being promoted by suppressing a cyclic operation in a period in which any data signal to be processed is absent in an equipment. CONSTITUTION: When the final input packet of a queue FA is transmitted to a matrix MC, and then aligned queues FA0-FA15 are all made empty, a signal the inverse of FV is turned into a 0 state, and a counter CT incremented by a signal H is released. When the counter CT reaches the maximum capacity N, a time DP=N/F (F is the frequency of the signal H) is timed out with the transmission of the final packet to the matrix MC, and switching to at least one of output multiplexes S0-S15 is ended. The output the inverse of C of the counter CT is turned into a 0 state, the counter CT is released, and a gate ET1 is closed. Thus, the transition of a signal is not operated in a switcher CP so that power consumption can be extremely reduced.

Abstract: PURPOSE:To form a normal image and a mirror image of an original picture with a simple constitution and a simple circuit, by providing a means which can set a subscanning done in a reading mode of the original picture in the direction adverse to the direction set when the original picture is read in the form of the normal image. CONSTITUTION:The light of a light source 21 at a reader part 20 of an image forming device is irradiated to an original 22 to be copied. The original 22 is shifted toward an arrow G or H, and the reflected light of the original 22 is reflected by mirrors 23 and 24 and made incident to a CCD 26. This reflected light is digitized by an A/D converter 27, and the image information is given to a printer part 30. A laser 31 of the part 30 delivers the laser light based on the signal given from the part 20. This laser light is supplied to a photosensitive drum 33 via a rotary polyhedral mirror 31. The drum 33 is revolved toward an arrow to copy the image formed by the electric information. Then a CPU 40, a normal image designation key 42, a reverse image designation key 45, a drive circuit 48, etc. are provided to the drive system of the image forming device. The subscanning done in a reading mode of the original 22 is set in the direction adverse to the direction set when the picture is read in the form of the normal image. Thus both the normal image and a mirror image are formed with a simple constitution.

Abstract: PURPOSE:To enhance hardness at the time of containing no water and to enhance oxygen permeability and strength at the time of containing water by polymerizing composition containing a fluorinated monomer, N-vinyl lactam, and unsaturated dicarboxylic alkyl ester, and specifying the water content of the polymer. CONSTITUTION:The composition containing the fluorinated monomer, the N-vinyl lactam, and the mono- or di-alkyl unsaturated dicarboxylate as essential components is polymerized. The water-content of the copolymer is controlled to >=30wt.%. When the fluorinated monomer component is too much, the water content of gel at the time of wetting lowers and when too little, staining resistance lowers, and when the N-vinyl lactam is too much, the mechanical strength of the gel at the time of wetting reduces, and when too little, the water content reduces, and when the ester is too much, the water content of the gel lowers, and when too little hardness and mechanical strength at the time of wetting lowers, therefore, it is preferred to select the composition comprising the 1-50wt.% fluorinated monomer, the 15-90wt.% N-vinyl lactam, and the 1-50wt.% unsaturated dicarboxylic alkyl ester to embody the soft contact lens.

Title: Semiconductor manufacturing apparatus
Inventor: SHIMIZU MASAHIRO
IPC: H01L21/027
Filed: 1984-05-08
Abstract: PURPOSE:To secure a wafer so that the plane thereof is perpendicular to light rays regardless of any possible warpage of the wafer, by employing an electrostatic wafer chuck. CONSTITUTION:An electrostatic chuck 7 secures a wafer 3 thereon by means of electrostatic force so that the plane of the wafer 3 is perpendicular to light rays 1. This is effected because the electrostatic force is sufficiently strong, and the wafer 3 can be retained in this state even if it has warpage. The wafer 3 is removed by blowing air against it through air holes 6. Since the chuck 7 reliably secures the wafer 3 so that the plane thereof is perpendicular to the light rays, there is no offset of focal point within the wafer 3, so that it is possible to increase the production yield.
