Title: Microcomputer
Inventor: SAITO HIROYUKI
IPC: G06F15/78
Filed: 1986-11-14
Abstract: PURPOSE:To reduce the load of soft to input key return data by synchronously accessing an address decoder and a key returning input port. CONSTITUTION:When a right switch on the key returning input port 10 is depressed, key return data corresponding to the kind of the depressed key are generated every generation of a pulse T0, inputted to a key return data writing buffer circuit 11 and outputted to a RAM 6. Since the MD2(0) of the RAM 6 is always specified as an address at the timing T0, the key return data are always inputted to the MD2(0). When a key indicating the succeeding digit is depressed, the key return data are generated at a timing T1 and the key return data are similarly stored in the MD2(1) of the RAM 6. Thus, the key return data are automatically stored in the RAM 6.

Title: Mobile identification unit
Inventor: NAGATA KAZUO
IPC: G01S13/75
Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To prevent erroneous function of responder by providing means for sustaining the high level of starting signal for a predetermined time at the end of communication. SOLUTION: Interrogation wave of an interrogator 50 is detected 3 and a detected 4 starting signal is delivered through a sustaining means 54 to a control circuit 8. The means 54 sustains the high level of starting signal for a predetermined time and the circuit 8 makes a transition from sleep mode to normal operation mode at the rising edge of starting signal. Consequently, a switch circuit 6 is turned on to feed 53 a power supply voltage to an amplifying circuit 5 and a modulation circuit 9. Based on an amplified 5 output signal from the circuit 3, the circuit 8 reads out a data and the circuit 9 modulates an interrogation wave to produce a response wave which is radiated back to the interrogator 50. Upon ending the response processing, the circuit 8 receives a communication end instruction of interrogator 50 and turns the circuit 6 off thus entering into sleep mode.  Since a switch circuit 14 is also turned off and the high level of previous starting signal is sustained 54 for a predetermined time, the sleep mode is sustained even if an interrogation wave is received thus preventing erroneous function of responder 51a due to noise.

Abstract: PURPOSE: To accommodate the maximum amount of radioactive waste with a structure design where weight is minimized by constituting a container with a shielding wall formed by a radioactive ray shielding material and a wall for structure for supporting the shielding wall that is partially formed by titanium. CONSTITUTION: An outer container 18 of a cask assembly body 1 has a shielding insert 22 according to the radioactive intensity of radioactive rays inside and a shell 20 for thermal protection is formed by a pair of semi-circle shell parts 24a and 24b.

When creating the outer wall 54 of the outer container 18 with titanium, the shell parts 24a and 24b are made of aluminum, magnesium, or the alloy. A decay heat generated by a radioactive substance retained in the cask assembly body 1 is propagated through the outer wall 54 of the outer container 18.  However, the thermal coefficient of expansion of the metal is large, the degradation heat cannot be extremely prevented by a shell 20 for thermal protection.

Abstract: PURPOSE:To stabilize the holding status of a shadow mask by forming a spring member for hooking the shadow mask to a stud pin, using two members, and connecting both members to each other for such construction as preventing the inter-torsion thereof. CONSTITUTION:A shadow mast 18 is fitted in such a way that a spring member 50 is fixed to a frame 19 forming a part of the shadow mask 18 and the support hole 54 of the spring member 50 is hooked to a stud pin 22. The spring member 50 comprises two members 51 and 52, while the member 52 is welded to the frame 19 and the member 51 is welded to the member 52. This member 52 has a support hole 54. If the member 52 is bent toward the axial direction of the stud pin 22 at the time of mounting the shadow mask 18, no permanent deformation takes place as the member 52 is bent together. A cut erection part 521 is formed on the member 52 and keeps a gap of about 0.5mm from the support side 514 of the member 51, thereby minimizing the torsion of both members 51 and 52. According to the aforesaid construction, the deformation of the spring member 50 is prevented and the shadow mask 18 is properly retained.

Title: Ink jet recording head
Inventor: KATAYAMA MASATO
IPC: B41J2/05
Filed: 1992-10-12
Abstract: PURPOSE:To suppress the effect of the pressure wave generated in a liquid passage by the emission of ink on other liquid passage and to form a dot having a stable size at a high speed. CONSTITUTION:A plurality of emitting orifices 4 are formed to the emitting orifice surface 5 of a recording head 1 and communicate with a liquid chamber 2 through respective liquid passages 3. Electrothermal converters 6 are provided to the respective liquid passages and ceramics pieces 7 are provided to the end parts on the liquid chamber 2 of both side surfaces of the liquid passages 3. The pressure waves generated in the liquid passages at the time of the emission of ink are propagated to the other liquid passages through the liquid chamber 2. Since the pressure waves at this time are absorbed by the ceramics pieces 7, the pressure waves are hard to propagate to the other liquid passages 3. As a result, the vibration of the ink in the other liquid passages 3 due to the pressure waves is suppressed and a dot having a stable size can be formed at a high speed.

Abstract: PURPOSE:To drive a tape in consideration of the influence of the mechanical load produced between reels or the tape load by controlling a servo circuit so as to keep a constant level of the counter electromotive force that is produced when one of a pair of reel motors is driven by the other one. CONSTITUTION:A take-up side supply reel motor 1 is used together with a supply side reel motor 2, a servo circuit 3 which controls the drive of the motor 1, a detecting circuit 4, and a switch circuit 5 which connects with switch the circuit 4 to the motor 2 and the circuit 3 to the motor 1 in accordance with the tape traveling direction. In such a constitution, the motor 2 is revolved via a tape in response to the drive of the motor 1. In this case, the counter electromotive force, i.e., the torque is produced and detected by the circuit 4. Then the drive of the motor 1 is controlled so that the voltage and the torque are kept at a constant level respectively. Thus it is possible to reduce the influence of the mechanical load produced between both reels or the tape load.

Abstract: PURPOSE:To present local information by transmitting a teletext signal attached with an address from a broadcasting station during the vertical blanking period of a video signal and broadcasting teletext information generated from the teletext signal received and decoded by a repeater station corresponding to this address by superimposing it on the video signal. CONSTITUTION:The teletext information and an address signal transmitted by a teletext broadcast transmitter receiver 21 during the vertical blanking period of the video signal are received, and the address is decoded by an address decoder 23, and simultaneously, the teletext information is decoded by a teletext signal processing circuit 22. When inputted address information is for its own repeater station, the address decoder 23 generates output, and switches a switching means 26 to a contact 26B. Accordingly, the output of a video IF amplification circuit 17 is inputted to a modulator 24, and the video signal is modulated by the teletext signal, and both the signals are mixed. The output of the modulator 24 is inputted to a filter 25, and a side band generated newly by the superimposition of the teletext signal is removed, and the output of the filter 25 is combined again with a sound signal by a mixing circuit 16, and becomes a television broadcasting signal. Thus, the local information can be presented.
