Title: Synchronizing system for supersonic switch
Inventor: INOUE HIRONOBU
IPC: H03K17/945
Filed: 1980-08-14
Abstract: PURPOSE:To prevent mutual interference between similar aparatus in an apparatus that detects existence of bodies by sending and receiving supersonic pulses by emitting a synchronizing signal of different frequency while reflected waves are present and suppressing a trigger signal while receiving a synchronizing signal. CONSTITUTION:By instruction of a trigger circuit 1, an oscillator 2 outputs f1 and an oscillator 12 outputs a synchronizing signal f2 and emits through an adder 11, an amplifier 3 and a transmitter 4. The output of a wave receiver 5 separates f1 in a filter 13 and controls the oscillator 12, and at the same time, rectifies and shapes in a signal processing circuit 15 to make it an output signal. The f2 separated in the filter 14 controls the trigger signal generating circuit 1 by a trigger suppressing signal generating circuit 10 through a rectifying circuit 16. However, while reflected waves f1 are present, the oscillator 12 continues to work by the output of the filter 13. The signal processing circuit 15 is controlled by a gate circuit 9 that determines timing to prevent detoured entrance of direct waves and incidence from remote places beyond the object of detection. By this way, mutual interference between nearby similar apparatus can be prevented surely through radio frequency f2.

Title: Serial bus connecting device
Inventor: TAWARA TAMOTSU
IPC: H04L69/40
Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To prevent a fault effect and to improve reliability by detecting a failure state through self-stack detecting means in a function unit and stopping a signal to a serial bus. SOLUTION: A self-stack detection circuit 40 is connected to serial bus output lines 36 on an output side of a serial bus output controlling part 35, and the on/off state of an output of three open collector driver elements 37-1 to 37-3 is controlled by an output enable line 50 that is connected to an output side of the means 40. The means 40 detects that any of three serial bus output lines 36 continues to output a signal for more than a fixed time (over the length that is impossible in a usual data transmission and receiving), and if it continues to output it equally to or more than the fixed time, the means 40 suppresses an output to a serial bus 20 by turning off the line 50 that is connected to the elements 37-1 to 37-3.

IPC: G11B17/056
Filed: 1980-08-18
Abstract: PURPOSE:To facilitate record replacement, etc., by turning a tone arm up to a play start position only when a turntable moves from a record-disk replacement position to a play position and a record disk has been placed on the turntable. CONSTITUTION:When a rack driving gear 15 is turned clockwise, a slide base 9 having an installed turntable 44 moves from a record-disk replacement position to the play position side of a player cabinet 1 together with a rack 16. At this time, the record detection pin 40 of the turntable 44 is held lowered by the weight of a record disk R and according to the turning of the turntable 44, a record detection lever 36 is inverted to make the end part 36b of the lever 36 engage with a guide cam 12, so that the base 9 stops at the play position. Then, a driving plate 28 coupling with the gear 15 through a crank 43 and a lead-in latch 29 nip a pin 24 implanted in a pickup plate 23 to turn the tone arm up to a play start position. Consequently, even if operation is started without the record R placed, the arm 5 will  not turn, thus preventing the damage, etc., of the pickup.

Abstract: PURPOSE:To eliminate the necessity of excess operation at the time of a normal initialization operation by executing a rechecking operation only when the information of a battery backup memory storing the control information of a stored medium and a real condition of a storing shelf are recognized by seeing the opening or the closing of the outside door of the device at a data recording medium automatic exchanging device. CONSTITUTION:This device is provided with an outside door opening/closing detecting mechanism 11 for machanically storing the opening/closing of a device outside door 5 and the condition of this mechanism 11 is detected by a shelf position detecting sensor 6. Also, a microswitch is attached to the outside door pening/closing detecting mechanism 11, the opening/closing of the outside door 5 is detected by a lutch circuit fed from a backup power source and held electrically. Thus, since the stored medium is managed without the medium existance sensor of the medium storing shelf, the stored medium management is operated at a reasonable cost and a reliability is improved by reducing a sensor.

Title: Information recording medium
Inventor: ISHIWATARI KAZUYA
IPC: G11B7/24024
Filed: 1988-05-12
Abstract: PURPOSE:To maintain good adhesive strength by forming a part worked with fine ruggedness to a region excluding a recording region on the surface of a substrate or protective substrate and using an adhesive agent of a hot melt type having weak adhesiveness to an adhesive agent layer. CONSTITUTION:The part 6 worked with the ruggedness of arbitrary shapes such as stripes is formed to the region 9 exclusive of the recording region 8 on the surface of the substrate 1. The use of the adhesive agent of the hot melt type which does not damage the recording layer 2 for adhesion of the substrate 1 and the protective substrate 4 is thereby enabled. While the provision of the part worked with the ruggedness on the protective substrate 4 is possible as well, the adhesiveness between the substrate 4 and the adhesive agent layer 5 is increased by activating the surface of the substrate 4 by a UV ozone treatment, by which the adhesive strength is increased and the exfoliation at the boundary face is substantially prevented. The good adhesive strength is, therefore, obtd. without disturbing the recording medium.

Filed: 1990-04-27
Abstract: PURPOSE:To obtain a code signal in which DC and low frequency components are less by utilizing data correlation so as to apply a prescribed coding processing to data in which the DC and low frequency components are decreased. CONSTITUTION:A block processing circuit 16 applies block processing to a non-correlation data D at an input terminal 10 into an n-bit data Da and an (n-p)-bit data Db. An input data Q at an input terminal 14 and from an output of a block correlation generating circuit 14 is subject to time adjustment by delay circuits 28, 26 respectively and the result is fed to contacts (a), (b) of a switch 30. In this case, n-bit data inputted to a DC component suppression coding circuit 32 have correlation with each other, and the DC component suppression coding circuit 32 employs the coding system in which the DC and low frequency components are decreased such as the 8-8 word invert coding for the combination of the n-bit data to encode the multiplexed n-bit data D<(m)>, Q via the switch 26. Thus, the code signal with less DC and low frequency components is obtained.

Title: Development device of copier
Inventor: SASAMOTO CHIHARU
IPC: G03G15/09
Filed: 1980-08-21
Abstract: PURPOSE:To always secure a proper amount of toner contined in the developer at the development region, by setting a bias roll at the upper part of a development roll with a gap secured and controlling the bias roll through applying the voltage to the same. CONSTITUTION:When the developer passes through a gap between a bias roll 5 and a development roll 8, only the toner attaches to the side of the roll 5 by the function of the electric field. Thus the toner moves upward along with the rotation of the roll 5. Here the voltage to be applied to the roll 5 is varied, and thus the toner content in the developer that has passed through the roll 5 can be changed in a free and quick way. The developer that has passed through the roll 5 is controlled to a proper upstanding tufts for development by a flow rate control plate 7. Then an electrostatic latent image on a photosensitive drum 1 is developed to a visible image at a development region. In such constitution, the toner content of the developer can always be set properly at the development region.
