Abstract: PURPOSE:To facilitate easy erasing and operation by starting automatically a partial erasion mode when a blackboard eraser touches an input surface, and executing partial erasing. CONSTITUTION:An input part of an electronic blackboard device contains the 1st and 2nd group electrode terminals 51 and 52, a partial erasion mode detecting circuit 53, a voltage detecting circuit 55, an output terminal 56, sample holding cir- cuit 61 and 63, a control signal generating circuit 56, etc. together with the 1st and 2nd parallel electrode groups 2 and 3 for detection of X and Y coordinates. Then the 3rd electrode groups Q1-QR are added newly. These 3rd electrode groups are not connected to registers 4 and 5 to which the groups 2 and 3 are connected and used for discrimination between the input and partial erasion modes. Here it is automatically discriminated whether the pressure is applied to an input surface by a writing tool like a chalk, etc. or an eraser. If a chalk is decided, the contents of the chalk are displayed on a monitor screen. While the corresponding display contents are erased in case an eraser is decided. Then an input mode is set automatically when a partial erasion mode is over.

IPC: G11B20/06
Filed: 1990-09-12
Abstract: PURPOSE:To suppress spike noise attending upon a head changeover by changing outputs of 1st and 2nd FM demodulation means into an over-lapping period of a reproducing track of a tape-like recording medium. CONSTITUTION:A signal recorded on a magnetic tape 10 is reproduced by rotary heads 12 and 14 alternately. An output of the rotary head 12 is impressed upon an FM demodulation circuit 52 via a preamplifier 16, (a)-point of a switch 40, a BPF 44 and a limiter 48, while an output of the rotary head 14 is impressed upon an FM demodulation circuit 54. Outputs of the FM demodulation circuits 52 and 54 are changed by a switch 58 to be changed by a head switching pulse HSWP into the overlapping period to become continuous, and an output of the switch 58 is outputted via (a)-points of switches 60 and 62 to obtain the same reproduced sound signal from output terminals 64 and 66. Since the reproduced sound signal after FM-demodulating is changed by the head switching pulse HSWP, head switching noise is suppressed not to be superimposed over the reproduced sound signal.

Title: Vertical type heat exchanger
Inventor: MAKIHARA KATSUMI
IPC: F28D7/16
Filed: 1985-10-31
Abstract: PURPOSE:To reduce remarkably a temperature difference in the thickness of a bottom tube plate upon the initial supply of water and prevent the breakage, deformation, craking due to thermal fatigue or the like of the bottom tube plate by providing a filler layers, consisting of a multitude of solid matters, on the bottom tube plate in a shell. CONSTITUTION:A filler layer 10, filled with the multitude of solid mattes such as steel balls or the like for example, is provided on the surface of a bottom tube plate 3b in a shell 1. The inner side of the shell is heated previously by high-temperature heat medium, flowing through tubes, therefore, water supplied into a heat exchange deprives heat from the filler layer 10 and the bottom tube plate 3b and is evaporated while the filler layer 10 precludes generated steam from being released from the bottom tube plate 3b as well as water from being supplied onto the upper surface of the bottom tube plate 3b, and a steam layer is formed easily on the upper surface of the bottom tube plate 3b. The steam layer serves as a large heat resistance. Filler, such as the steel balls or the like, precludes contact between the water and the bottom tube plate 3b as well as cooling from the upper surface of the same plate 3b and, as a result, a temperature difference in the direction of the thickness of the bottom tube plate 3b can be reduced remarkably.

Title: Diesel engine with auxiliary chamber
Inventor: NAKAE KOICHI
IPC: F02B23/02
Filed: 1990-09-17
Abstract: PURPOSE:To enhance an air utilization factor by covering an opening of an intake valve on an exhaust valve side with a mask wall, making an interval between a pair of intake valves larger than that between the exhaust valves, and forming an injection hole of an auxiliary chamber on the inner wall surface of a cylinder head most apart from the exhaust valve among the intake valves. CONSTITUTION:An exhaust valve 7 is opened and closed prior to an intake valve 5. The exhaust valve 7 is opened, and then, after gas combustion is exhausted into an exhaust port 8. Since an opening of the intake valve 5 positioned on the exhaust valve 7 side is covered with a mask wall 15, most of fresh air flows along a conical circumferential wall portion 16 on the side opposite to the mask wall 15, thus generating a loop scavenging air flow. Fuel is injected into an auxiliary chamber 9 from a fuel injection valve 11 in the final stage of a compression stroke, for ignition combustion. A pressure inside the auxiliary chamber 9 is increased, and unburned mixture and combustion flame injected from an injection port 10 are mixed with air staying inside a recessed groove 13, for ignition combustion. Meanwhile, since an interval between the intake valves 5 is large, the unburned mixture and combustion flame proceeding between the exhaust valves 7 without being inhibited by the mask walls 15 flows in a lower space 17 formed downward at the time of closing of the exhaust valves 7, for ignition combustion.

Title: Optical information recording device and optical information recording medium used therefor
Inventor: AWANO HIROYUKI
IPC: G11B7/00
Filed: 1994-10-07
Abstract: PURPOSE: To enable recording and reproducing of optical information using recording marks smaller than the wavelength of the light source. CONSTITUTION: A slider 18 provided with an optical head 15 on one side of the optical information recording medium 30 and with a reflector on the other side of the medium 30 is disposed. The recording light emitted from the optical head 15 penetrates the medium 30, and is partly reflected with the reflector to re-enter the medium 30 and form a recording mark there. The reproduction light emitted from the optical head 15 penetrates the medium 30 and is partially reflected to penetrate the medium 30 again and be received by the optical head 15. By this process, the recording mark in the medium 30 is read out. Therefore recording marks smaller than the wavelength of the light source are formed to allow recording and reproducing information accompanied by improved crosstalk.
