Title: Tape recorder
Inventor: KAGE SHINGO
IPC: G11B15/675
Filed: 1991-10-04
Abstract: PURPOSE:To load/unload two kinds of cassettes with the same loading mechanism by forming and holding protrusions which engage with each hole of two kinds of the cassettes, so as to move the cassette up to the recording/ reproducing position. CONSTITUTION:A tip part 1d of a conventional cassette ACC 1 abuts against the 1st protrusion 4a on a holding member 4, and an arm part 4b is deflected when further inserted, then the protrusion 4a runs over a housing part. When the cassette is inserted further, a reel shaft inserting hole 1a of the ACC 1 reaches the position opposite to the protrusion 4a, therefore, the protrusion 4a and the hole 1a are engaged by an elastic recovery of the arm part 4b and held by the member 4, then the cassette is moved to the recording/reproducing position by the rotation of arm member 5. For a digital compact cassette DCC 2, the protrusion 4a is not engaged with a grip slot of the DCC 2 by the insertion, and the protrusion 4c abuts against the tip part and deflected. With the further insertion, the grip slot is engaged with the protrusion 4c and the cassette is moved to the recording/reproducing position by the rotation of the member 5.

Title: Video recording device
Inventor: NAGANAMI MINORU
IPC: H04N7/18
Filed: 1988-10-13
Abstract: PURPOSE:To effectively record the pictures of visitors by starting a timer means to store the photographed pictures in case a call signal is received in an inactive state of the timer means. CONSTITUTION:When a detection signal is inputted from a doorphone call detecting circuit 3, a CPU 1 decides whether or not a timer which inhibits a picture recording action is working. The timer has a time-up state when a prescribed time passes after its start. In case a call signal is received in an inactive state of the timer, the still pictures equivalent to one frame are stored in a memory 2 from a picture signal/synchronizing signal separating circuit 4 via a synchronizing signal. The timer is started to inhibit the picture recording actions until the time-up. Thus the same picture is not recorded repetitively even though a call switch is mischievously pushed in many times. Furthermore the photographing operations are inhibited while the timer is working. Thus it is possible to effectively record the pictures of visitors with use of the memory 2 of a small capacity.

Filed: 1985-11-18
Abstract: PURPOSE:To improve a field-through characteristic without losing the shield operation of a holder by forming the holder as a ring shape opened electromagnetically. CONSTITUTION:A slit 13 is formed over the entire width of the holder 12, which consists of a holder main body 14 made of brass formed with a ring shape opened electromagnetically and a synthetic resin made reinforcement plate 15 bonded to bridge over the slit 13. A write head 4(5) generates a magnetic flux phi shown in broken lines. A part of the magnetic flux phi acts like the holder main body 14, an eddy current is generated at a part of the holder main body 14, and since the holder main body 14 is a ring shape opened electromagnetically, the flow of the loop-shaped eddy current is disturbed by the slit 13 and no eddy current flows. Thus, only a part of the magnetic flux phi generated by the write head 4(5) is acted onto the coil of a read head 6(7) so as to show an excellent field-through characteristic.

Abstract: PURPOSE:To obtain an accurate timing signal without any adjustment under the influence of none of the responsibility, temperature variation, and the source voltage variation of a photocoupler by detecting the peak of the output signal of the photocoupler and inverting the output of an FF. CONSTITUTION:When a leading curtain begins to run, a cam 40 rotates and a projection part 41 cuts off luminous flux 51a from an LED51 temporarily to raise the output e1 of a phototransistor PT52; when the projection part 41 passes through the luminous flux 51a, the output e1 drops. The time position of the peak value of the output e1 is constant when the rotating speed of the cam 40 is constant. The output e2 of a capacitor C3 and an amplifier A11 is held at the peak voltage with the output e3 of an amplifier 10, and an amplifier A10 operates as a comparator, so that outputs of gates G1 and G2 forming the FF are inverted according to variation in the level of the output e3. Transistors Q4 and Q5 are therefore turned off with the output of the G2 and the C2 begins to be charged, thereby clocking a shutter second time.

Title: Micro fabrication method for semiconductor device
Inventor: SAKOU YAMATO
IPC: H01L21/3063
Filed: 1994-09-28
Abstract: PURPOSE: To effectively smooth a semiconductor substrate itself or the surface of a film piled up thereon by pressing a probe onto the surface for scanning while a voltage is applied to between a layer having the surface to be smoothed and the probe in an electrolyte. CONSTITUTION: While a substrate 1 and a probe 5 are dipped in a KOH aqueous solution, a voltage of around 1mV is applied to between them and a tip of the probe 5 is pressed down to the surface of bottom 3 of a hole 2 at a pressing force of about 3nN-3000nN so as to scan the entire surface thereof. Through such an operation, the surface roughness of around 1.0nm thereof is changed into around 0.10nm. This results from a synergistic effect between the electrochemical action of voltage application in an electrolyte and the physical action by pressing force. Thus, only a fine area can be smoothed effectively and the deterioration of electrical property due to surface roughness can be prevented as well.

IPC: G05B9/02
Filed: 1988-10-14
Abstract: PURPOSE:To start communication by again making synchronization even when a receiving side loses a frame by transmitting a frame to which a clear bit is turned on for starting normal communication when an alarm is issued. CONSTITUTION:When an alarm signal is transferred from a spindle amplifier 20 side or no normal response is made against the transfer from a numeric controller(CNC) 10 side when power supply is made or due to noise, etc., the CNC 10 side turns on a clear bit and transfers data of one frame quantity by considering that the spindle amplifier 20 side loses a frame. Upon receiving the frame to which the clear bit is turned on, the spindle amplifier 20 side clears a frame counter and abandons the received data irrespective of the frame being received and the CNC 10 side again starts normal communication. Therefore, when abnormality occurs, communication can be restored between a CPU unit 11 and peripheral unit 21 after making synchronization.
