Title: Magnetic eraser
Inventor: SAITOU YOSHIO
IPC: G11B5/127
Filed: 1979-09-22
Abstract: PURPOSE:To erase the magnetism of a magnetic tape automatically by demagnetizing the magnetic tape by moving the tape through the gap between a couple of channel-shaped iron cores wound with coils and by stopping the tape by detecting the tape passing. CONSTITUTION:A couple of channel-shaped iron cores 1 are wound with coil 3 and, while width A of the gap is made greater than the thickness of magnetic tape cassette 2, are arranged opposint to each other. When tape cassette 2 is inserted into gap A with main switch 13 on, microswitch 14 turns on to input the output of transformer 16 to voltage regulator 19. With the output of voltage regulator 20, coil 20 are excited to make contact 18, so that motor 8 rotates. At the same time, demagnetizing coils 3 are excited. Through motor 8, tape cassette 2 passes in the gap to demagnetize the magnetic tape and when cassette 2 moves a prescribed distance away from iron core 1, microswitch 15 is turned off to break contact 18, so that the excitation and motor stop. Therefore, magnetic erasure is automatically carried out.

Title: Receiver of multifrequency signal
Inventor: KANEKO TAKAO
IPC: H04Q1/457
Filed: 1982-07-13
Abstract: PURPOSE:To attain the economy at circuit integration, by multiplexing a band pass filter and a detecting circuit and operating them in time series to each channel of a multifrequency signal for decreasing the occupied area and power consumption of the filter and the detecting circuit. CONSTITUTION:The multifrequency signal divided into groups at band stop filters 1, 2 is inputted to limiter circuits 3, 4, where the signal level is detected and a rectangular wave having a period equal to a signal is outputted. Thus, an input signal of multiplex band pass filters 21, 22 is a rectangular wave having a equal period to one frequency among each four frequencies of low and high groups. The multiplex band pass filters 21, 22 have equal gain and Q, the center frequency is controlled for the filters from the channel 1 to the channel 4 split into four kinds of frequencies respectively for high and low groups by providing four sets of timing with a clock and is operated in time series. Thus, the occupied area and power consumption of the filters 21, 22 and the detecting circuits 23, 24 are decreased, and the economy is attained because the scale of circuit is small in case of circuit integration.

Title: Keyboard input device
Inventor: NAGAOKA SHUICHI
IPC: H01H13/76
Filed: 1986-05-27
Abstract: PURPOSE:To omit a misinput preventing diode by setting no key at a position where the misinput is caused by a detouring current when plural keys are depressed at one time and delivering the key information only to the key existing at an intersecting point where the push is detected. CONSTITUTION:When plural keys, e.g., the function keys 40A and 40B and a data key 50A are pushed at one time, the pushes of these existing keys 40A-50A are detected at a CPU 70 and at the same time the scan pulses applied to a scan line X2 while those three keys are pushed emerge on a detection line Y3 via the keys 50A, 40A and 40B. Thus the push of the key supposed to exist at the coordinates (2, 3) is detected. Then the CPU 70 immediately decides whether or not the detected key is included in those existing keys registered to a memory. The non-existing keys are neglected and the information on only those existing keys 40A-50A are delivered outside in a prescribed processing procedure and by N key roll-over system.

Air stream in the air supply duct 4 is passed through the heater core 22 by the damper 44 and then through an indoor device 34. Therefore, the rise of blow-out temperature is more raised than in the case of heating only by the indoor device 34.

Title: Method for determining draft schedule of rolling mill
Inventor: OKADA KIMIYUKI
IPC: B21B37/00
Filed: 1991-04-25
Abstract: PURPOSE:To determine rolling conditions that the shape of thick plate at each rolling stand is made into a prescribed allowable shape without increasing the number of treatment and also that satisfies the capacity of mill. CONSTITUTION:On the step 102, while considering so that the increase or decrease of set value is possible, the initial values of rolling conditions of the set value of thickness, bender pressure, etc., at each rolling stand are determined. On the step 106, while using the shape conditions at each rolling stand, the changing amount of thickness at each rolling stand is simultaneously determined from the deviation of crown at the final stand. And, on the step 108, in the case the obtained changing amount of thickness doesn't satisfy the capacity of mill, bender pressure at each stand is changed. Because the initial value is possible to increase or decrease the set value, the number of loop in the whole process can be reduced. It is not feared that the change is executed at only a specific rolling stand.

Abstract: PURPOSE:To improve electron mobility, and to increase working speed by crossing and disposing a gate electrode controlling an electron gas generated near a region, in which an impurity reaches only to the second semiconductor layer side on the interface of a hetero-junction, in the direction of stripe. CONSTITUTION:Both an Al0.3Ga0.7As layer 2 and a GaAs layer 3 are epitaxial-grown onto a semi-insulating GaAs substrate 1 in a non-doping manner. A mask 11 in which a large number of striped patterns are formed in a region in which a channel is shaped is formed onto the semiconductor base body by using SiO2, etc. on the layer 3. Ions such as silicon (Si) ions are implanted, and Si ions are activated and diffused through heating. Consequently, the N-type regions, into which Si is doped, of 4a in the GaAs layer 3 and 4b in the AlGaAs layer are formed. The N-type regions 4a, 4b into which Si is introduced are also shaped in ohmic contact forming regions. Sections not coated with the mask 11 in the Si introducing regions in the GaAs layer 3 and the AlGaAs layer 2 are removed regarding at least the channel forming region, and layers such as non-doped GaAs layer 5 are buried and grown in the sections. The N-type regions 4a, 4b are left regarding the ohmic contact forming regions. A gate electrode 7 is arranged crossed in the direction of stripe of a channel region shaped through said process.

Abstract: PURPOSE:To make a stable, accurate steering angle detecting action securable, by detecting whether it rotates in which direction from a rectilinear position by means of symmetrical steering angle switches being closed with the specified angle rotation of a steering column. CONSTITUTION:When a steering column 1 is rotated by more than 180 deg., an outward projection 5 of a cam member 6 kicks an intermediate rocking arm 7 to the left of the specified angle, while an arm body 7b slides somewhat to the side of a gear 8, and its tip is instantaneously engaged with this gear 8 and further rotates a solidified switch plate 9 to the right a far as a position for one tooth, whereby a right steering angle switch terminal 10b comes into contact with a conductor part 13, and a right steering angle switch 3 is closed. When the column 1 further rotates a turn to the right, again the switch plate 9 is rotated as far as one tooth portion but in this time also, the right steering angle switch 3 alone is closed. And, when it is restored to a rectilinear state, both symmetrical steering switches 3 and 2 are opened. On the other hand, in time of rotation to the left, the left steering angle switch 2 is closed likewise.
