Title: Automatic marking device for examination paper
Inventor: OKANO NORIO
IPC: G09B7/00
Filed: 1990-05-25
Abstract: PURPOSE:To minimize the burden of work to a marker and to easily generate detailed educational materials by directly reading marking symbols entered on an examination paper by manual work and discriminating whether they are correct or not and automatically calculating the marks. CONSTITUTION:When an examination paper P is placed on a marking board BD and marking symbols are entered for individual answer columns A1 to A5, their coordinate data are read by the marking board BD. A position recognizing means 11 recognizes positions where marking symbols are entered based on read coordinate data, and a correct/wrong discriminating means 12 discriminates whether marking symbols are correct or not, and an allotment processing means 13 uses outputs of the position recognizing means 11 and the correct/wrong discriminating means 12 to determine correct or wrong answers in individual answer columns A1 to A5 and calculates the obtained marks. Thus, the burden of work to the marker is minimized, and marking data including correct or wrong answer results of respective questions at every student is automatically accumulated to automatically generate detailed educational materials.

Title: Conductor for connection of semiconductor device
Inventor: SAWADA KAZUO
IPC: H01L23/48
Filed: 1985-06-21
Abstract: PURPOSE:To obtain the titled conductor for connection made of Al alloy which is improved in ball-forming property in ball bonding without deteriorating electric conductivity and corrosion resistance by providing a composition consisting of prescribed percentage of Pb and the balance Al. CONSTITUTION:The conductor for connection of semiconductor devices consists of 0.1-10wt% Pb and the balance Al, to which 0.2-2wt% of 1 or >=2 elements preferably selected from the group consisting of Si, Mg, Mn and Cu are incorporated so as to improve strength and workability. The above conductor for connection excels in ball-forming property in ball bonding as compared with the one made of conventional Al alloys. It is thought that the above effect results either from the increase in surface tension or from the change in characteristics of the oxide film formed on the surface in the melting at the time of ball formation, owing to Pb contained in the above prescribed percentage.

Title: Improved winding preventive device for web printing machine
Inventor: RONARUDO KARAN
IPC: B41F33/14
Filed: 1996-05-07
Abstract: PROBLEM TO BE SOLVED: To prevent the damage to printing machine rolls when a printed web product is broken by installing means which are arranged at intervals in the length direction of upper and lower rollers and make the rollers line- contact the web and other means. SOLUTION: Since the breakage of a web occurs downstream from printing units, an anti-warp device is arranged between the last printing unit 10D and a drier. When the web detector 25 of the drier detects the breakage of webs in a drier unit, different from a conventional system, while a printing machine unit is decelerated to be stopped completely, the anti-warp device is constituted so that rolls pull out the webs 30 from printing units 10A-10D, and the matching of the speeds of the printing machine rolls is not required. Since the webs 30 are led from the printing units to be collected in the floor space between the apparatus 50 and the drier, broken webs are returned upstream from the drier unit to be prevented from being wound onto a blanket cylinder 5 of the printing unit 10D and others.

IPC: G11B17/04
Filed: 1994-06-20
Abstract: PURPOSE:To prevent the end of a disk cartridge from abutting on a lower side magnetic head in the case of inserting the disk cartridge in a holder. CONSTITUTION:The magnetic disk device 1 is constituted by assembling the holder 5, a slider 15 and a shield cover 16 on a frame 2 in an overlapped state. An abutting preventing member 21 regulating the insertion height position of the disk cartridge 4 in the case of inserting the disk cartridge 4 in the holder 5 is freely burnably provided on the frame 2. The member 21 has a guide part 21a guiding the disk cartridge 4 to the insertion height position where the cartridge 4 does not abut on the lower side magnetic head 10 by running onto a projecting part 24 on the frame 2. Since the engaging pin 15m of the slider 15 is directly engaged with a fitting hole 21d, the member 21 turns to an abutting preventing position or an abutting prevention releasing position as the slider 15 slides in a direction AB.

Title: Heated toilet seat
Inventor: OSHIMA KOJI
IPC: A47K13/30
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To prevent a toilet seat from being too hot or too cold and to save energy with high instantly heating property by magnetically shielding a temperature detecting element in a heated toilet seat. SOLUTION: The temperature detecting element 5 detects the temperature of a heater and a controller controls a power source for induction heating by an output value from the element 5, to control the heater at a proper temperature. Then, since the element 5 is in close contact with the heater through a thermal conductor 7 of high thermal conductivity, the heat is quickly transmitted to more precisely measure the temperature of the heater. In addition, as the element 5 is covered with a magnetically shielding material 6 consisting of a ferromagnetic body, the element 5 interrupts a magnetic field generated from an energizing coil for heating and never generates the raising of a temperature due to induction heating.  In addition, as the material 6 is an electrically insulated body or a semiconductor, the raising of a temperature due to the induction heating of the material itself is reduced and a temperature is measured precisely without giving influence to the generated magnetic field.
