Title: Electronic dehumidifier
Inventor: NOGUCHI YASUTAKA
IPC: F24F1/00
Filed: 1986-09-16
Abstract: PURPOSE:To provide an electronic dehumidifier which is simple in construction, compact and low in noise by disposing an electronic cooling element and using one side of a set of vanes of a fan as a cooling side and the other side as a heat releasing side. CONSTITUTION:When a cooling fan 8 and a heat releasing fan 9 are operated, humid room air is introduced from a cooling side inlet 2 by cooling vanes 8a end heat releasing vanes 9a, and said air is delivered into the room from a cooling side outlet 3 and a heat releasing outlet 7. When a DC power is supplied to an electronic cooling element 4, a thermal flow is generated in the direction of the electron flow in an N-type semiconductor 18 and in the direction of the hole flow in a P-type semiconductor 19, and so a cooling plate 8a becomes at a low tempereture and a radiation plate 9b at a high temperature. Therefore, the air flowing along the cooling vanes 8a and cooling plate 8b loses its temperature by exchanging heat with the cooling vanes 8a and cooling plate 8b. Such air is cooled below the dew point temperature to cause the water vapor to dew on the cooling vanes 8a and cooling plate 8b to be dehumidfied. As the fans 8, 9 and electronic element 4 are unitized to make the space for air passage as small as possible, the construction can be simplified and compact. Since there is no movable part in the electronic cooling element 4, the noise can be reduced.

Title: Semiconductor device taking advantage of gunn effect
Inventor: IMURA KIMIHIKO
IPC: H01L47/02
Filed: 1990-08-17
Abstract: PURPOSE:To obtain a semiconductor device which is wide in variable frequency and quickly changeable in frequency by a method wherein a voltage is applied between an anode electrode and a cathode electrode so as to make an electrical field between them higher than a critical electric field where a Gunn domain is induced, and a bias voltage is applied to a Schottky electrode so as to enable a depletion layer to expand under the Schottky electrode as wide as the surface depletion layer of an N-type semiconductor layer. CONSTITUTION:When an N-type semiconductor layer 4 is used as an operating layer, a critical electric field which enables a Gunn domain to be induced is 3kV/am or so. Therefore, when a certain bias voltage is applied to all Schottky electrodes 11, 12, and 19 so as to enable depletion layers to expand under the Schottky electrodes as wide as the surface depletion layers between the Schottky electrodes while a direct current voltage of 3kV/cmX100mum or 30V is applied between an anode and a cathode, a Gunn domain is made to occur in the N-type semiconductor layer 4 on a cathode electrode 6 side and dissipates after it travels a distance of 100mum between a cathode and an anode. At this point, as an electron saturation speed is 10<7>/s, an oscillation frequency becomes nearly equal to 10GHz.

Title: Original placing plate
Inventor: SUZUKI TSUNEO
IPC: G03B27/62
Filed: 1982-12-09
Abstract: PURPOSE:To surely hold an original on an original placing plate and, at the same time, to prevent flying down and breakage of an original, by installing a soft member which at least has an original holding function as the original placing plate or original keeper. CONSTITUTION:At the back of an original keeper 4 an original keeping sheet 7 composed of a soft member is fitted in such a way that both sides of the sheet are glued to the original keeper 4 and the central part is slackened. At the time of copying, a prescribed original 11 is placed on a prescribed location on a glass plate 3 on an original placing plate 2 and the original 11 is fixed to the glass plate 3 by closing the original keeper. Since an elastic projected band 6 installed to the rear section of the original placing plate 2 is an elastic body and deformed when pressed by the original keeper 4, the original keeper 4 and original do not rise and no copying light leaks out. Moreover, because of the slackened part at the central part of the original keeping sheet 7 fitted to the back of the original keeper 4, the original keeper 4 firmly adheres to the original 11 and slipping of the original 11 due to vibration and impact can be prevented.

Title: Synchronous motor controller
Inventor: KAMEI KAZUNORI
IPC: H02P21/22
Filed: 1990-08-16
Abstract: PURPOSE:To reduce the size and to shorten the processing time by detecting the current flowing through an inverter circuit and determining a current command value based on the difference between the detected current value and a target current value thereby employing only one current detector. CONSTITUTION:A current control means 10 amplifies the difference between a target current value Ic fed from a host system or a speed amplifier and a current value If fed back from a current detector and a current command value is fed to a multiplying means 9. The multiplying means 9 multiplies the output from the current control means 10 by three signals, obtained by converting the output from a position detector 2 according to a ROM table in a sine wave generating means 8, and provides the products to PWM circuits 5, 6, 7, respectively. Switching transistor in an inverter circuit 3 is then turned ON/OFF by the PWM signal and current flows through each phase coil of a synchronous motor 1 thus rotating the synchronous motor 1. Since only one current detector is required, the size of controller is reduced and since multiplication is required only one time, processing time of microcomputor is shortened in current control.

Title: Optical information recording and reproducing device
Inventor: SASAKI KENICHI
IPC: G11B7/127
Filed: 1993-08-10
Abstract: PURPOSE:To eliminate interference between light spots and to make setting operation stable by putting off light except a light spot for detecting a focusing error signal until setting operation is completed at the time of focus setting. CONSTITUTION:A semiconductor laser diode 1 has two light emitting section 1a, 1b and the laser 1a is a light spot for detecting focus error. A control section makes a disk 5 rotate, turns on the laser 1a, and moves an object lens 4, at the time of focus setting. During the time, since a servo signal detecting light flux is in out of focus, an adjacent detector for detecting light for verifying also is in out of focus in light detector 9, 10. However, since the laser 1b for verifying spot is put off, a light flux does not exist on the surface of the detector and interference between light spots does not occur. After that, the laser 1b is turned on at the time of finish of setting operation by the laser 1a, and a recording and reproducing state by the laser 1a and 1b is obtained. Thereby, interference between light spots is prevented and setting operation is stabilized.
