Title: Apparatus and method for detecting wafer polished condition
Inventor: SHIBATANI HIROSHI
IPC: B24B37/013
Filed: 1999-11-12
Abstract: PROBLEM TO BE SOLVED: To provide an apparatus and a method for detecting the wafer polished condition detectable for each head with high sensitivity, and in particular, favorable for detecting the polishing terminal of a multi-head type grinding apparatus. SOLUTION: Two sets of strain gages R1-R4 mounted on a diaphragm 212 at the positions symmetrical to the center of the diaphragm detect the displacement of the diaphragm 212 to indicate the polished condition. The displacement of this diaphragm 212 is converted to the voltage displacement by a Wheatstone bridge circuit formed of the strain gages R1-R4, and then, amplified by a differential amplifier 132. Then, the displacement of the diaphragm 212 converted into the voltage displacement is attenuated in the disturbance noise by a low pass filter 124. A synchronous detection circuit 125 makes the detection synchronous to the rotation of the head to form and output the polished condition signal C1 of the diaphragm 212. The polishing terminal is detected by comparing this polished condition signal C1 with the information on the polished terminal stored in a database 113.

Title: Production of magnetic recording medium
Inventor: YOSHIMURA MAKOTO
IPC: G11B5/84
Filed: 1992-12-03
Abstract: PURPOSE:To improve the smoothness on the surface of a magnetic layer by setting the peripheral surface temp. of metallic rolls forming nips with an elastic roll lower than the glass transition point of the magnetic layer of the magnetic recording medium. CONSTITUTION:The peripheral surface temp. of the metallic rolls forming the nips with the elastic roll is set lower than the glass transition point of the magnetic layer of the magnetic recording medium in the case the magnetic recording medium is passed through the nip of a pair of the metallic rolls and is then passed through the nip with the metallic rolls. Namely, the peripheral surface temp. of the metallic rolls 6, 10 forming the nips with the elastic roll 8 is set lower than the glass transition point of the magnetic layer of the magnetic recording medium 20. As a result, the rapidity of staining the peripheral surfaces of the metallic rolls 6, 10 forming the nips with the elastic roll 8 is retarded while the smoothness of the magnetic layer surface of the magnetic recording medium 20 is improved. The productivity is thus improved. The setting of the peripheral surface temp. of the respective metallic rolls 2, 6, 20 in contact with the magnetic layer is executed by a heating mechanism (not shown in Fig.) provided within the respective metallic rolls 2, 6, 10.

Title: Ink jet facsimile equipment
Inventor: YANAI AKIO
IPC: B41J2/01
Filed: 1994-12-27
Abstract: PURPOSE: To prevent the occurrence of the state of fall-back and to prevent the increase of communication time and communication cost by detecting the remaining capacity of a reception memory, comparing reception speed with printing speed and automatically varying printing speed. CONSTITUTION: A main control part 1 detects the remaining capacity of the reception input picture memory 2. When remaining capacity is judged as small, a recording control part 8 controls the system to execute printing at a high speed thinning mode. When remaining capacity is judged as large, printing is executed at a standard mode when a printing dot is not thinned. Then, a line is released and communication is terminated. The main control part 1 compares reception speed decided in a procedure before the reception of picture data with printing speed at the standard mode. When reception speed is faster than printing speed, the recording control part 8 controls the system to execute printing at a high speed thinning mode. When reception speed is slower than printing speed, printing is executed at the standard mode. Then, the line is released and communication is terminated.

Title: Electrifier for image forming device
Inventor: SATO MASUMI
IPC: G03G15/02
Filed: 1997-11-26
Abstract: PROBLEM TO BE SOLVED: To prevent an electrifying roller from minutely vibrating in the direction of its radius when starting to rotate, with the result that an electrification irregularity occurs. SOLUTION: The electrifying roller 3 and a cleaning member 4 for cleaning the surface of the electrifying roller 3 are supported by means of a cleaning hold member 5 and a pair of swing arms 11 with an even distance L between them. Therefore, when the electrifying roller 3 tends to vibrate minutely in the direction of its radius at the start of its rotation, the cleaning member 4 also tends to vibrate minutely in the same direction together with the cleaning hold member 5. However, a plate spring 15 for minimizing the vibrations is in contact with the cleaning hold member 5, therefore, the vibrations can be restricted to the smallest degree at which an electrification irregularity does not occur.

Abstract: PURPOSE:To increase the breakdown strength of a second gate insulating film existing between a control gate electrode and a floating gate electrode by mutually connecting the control gates of memory cells adjacent in the row direction through a first contact hole being penetrated through a first interlayer insulating film and reaching the control gate. CONSTITUTION:Contact holes 14 communicated with each control gate electrode 8 are bored to an interlayer insulating film 13. Wirings 15 are arranged through the holes 14, and electrodes 2 adjacent in the channel cross direction are connected respectively. Consequently, the control gate electrodes 8 can be operated as word lines because they are bonded mutually by the wirings 15. Since no cell slit is formed in polycrystalline silicon layers 6, the surfaces of the layers 6 are brought to an extremely flat state, second gate insulating films 7 are shaped, and there is no position where the corners of the floating gate electrodes 6 generating electric-field concentration and the electrodes 8 are faced oppositely among floating gate electrodes 4 and the electrodes 8. Accordingly, the breakdown strength of the insulating films 7 is increased.
