A secondary air supply part 5 is provided in the exhaust passage 2 between the adsorbing member 3 and the EHC(electric heater catalyst) 4. When the engine 1 is in a lean operation area, NOX is adsorbed to the adsorbing member 3, and at the time of a stoichiometric air-fuel ratio or a rich operation area, the adsorbed NOX is released and purified together with HC and CO by the three-way catalyst. At the cold start time of the engine 1, the three-way catalyst is heated by the heater.

Title: Tape cartridge
Inventor: GOTOU SHINICHI
IPC: G11B23/087
Filed: 1985-04-05
Abstract: PURPOSE:To prevent a tape from contacting and interfering with the upper edge of the opening when pulling out the tape and to prevent damage to be inflicted on the tape by setting the upper edge of the opening of a tape outlet at the position which is deviated from a tape guide surface of right and left edges of the opening to the backward of a case main body. CONSTITUTION:Opening right and left edges 4b, 4c of right and left tape outlets 4 are formed in a half-cylindrical shape in cross-section so as to be a guide surface of a tape 2, while an opening lower edge 4d is caused to protrude slightly forward from the opening right and left edges 4b and 4c and raised slightly higher than an inner face 9b of a bottom wall 9, thereby limiting downward actions of the tape 2. An opening upper edge 4a is set at the position deviated to the case backward from the right and left edges 4b and 4c and the lower edge 4d. As a result, even if the tape 2 is inclined upward due to rips, etc., of a tape guide pin at the time of the tape pulling out travel, the tape can avoid being contact with the opening upper edge 4a, and the tape bending and damages can be prevented accordingly.

A flat back plate 5 is provided on the lower surface of the luminescent layer 4 and a moisture-proof rear surface layer 6 is provided on its lower surface. There is no problem in visibility of luminescence from the luminescent layer 4, because the hexagonal feeding body 3 comprises fine wires. A clear image of a letter or a figure can be obtained. Power is supplied to the feeding body 3 from wide collectors on its end surface sides. Since the transparent electrode 2 randomly receives power from many contact positions of the feeding body 3 right under it, it is seldom influenced by the resistance of the transparent electrode 2.  Uniform electroluminescence having high luminance can be materialized.

IPC: H04N5/44
Filed: 1991-03-13
Abstract: PURPOSE:To automatically select and output a received signal. CONSTITUTION:A photodiode 11 receives a signal outputted from a transmitter 2 through infrared rays and converts the received signal into an electric signal. The signal is inputted to a level detecting circuit 29 through a BPF 21 and an amplifier 22. When the level of the inputted signal is turned to a level larger than a reference level set up by a reference value generating circuit 28, the circuit 29 outputs a detection signal to a control circuit 35. At the time of inputting the detection signal, the circuit 35 automatically switches both switches 31, 32 to the contact (a) side. Consequently a signal FM-modulated by an FM modulator 24 is outputted from an output terminal 33 through an amplifier 25 and a switch 31.

Title: Erasure characteristics enhancing circuit for nonvoltatile memory
Inventor: OSAWA HIROSHI
IPC: G11C16/06
Filed: 1995-03-30
Abstract: PURPOSE: To enhance the data erasure characteristics of EEPROM by controlling the magnitude of data erasure voltage for each memory cell depending on the current flowing through the bit, line of a nonvolatile memory. CONSTITUTION: In an EEPROM, a read voltage is applied in order to convert the current flowing on a bit line 8 into a voltage through a sense amplifier 12. The voltage indicative of the current is then converted through an AD converter 13 into a digital value. An operational logic unit 18 compares the digital output from the AD converter 13 with a value read out from a ROM. When a logical operation output indicative of unmatching is delivered from the unit 18 to a decision section 17, count in a program counter 16 is altered to match with an output read out from a mask ROM 15. Consequently, a matched output data is delivered from the unit 18, the count in the counter 16 is altered, a table data is read out from the ROM 15, a corresponding control bit is set in a register 20 and negative charges in an MOS transistor 6 are offset.

Filed: 1984-04-13
Abstract: PURPOSE:To use a tape recorder for both answering at the time of absence and recording talking contents at the time of presence, by providing a means which changes the stopping position of a tape for the absent mode and present mode times. CONSTITUTION:When an absent selecting button is depressed, a CPU8 first rewinds a tape and, when detecting the CUE signal at the top of an outgoing message (OGM), sets a tape recorder to a reproducing mode. When an incoming call is made, the OGM is automatically reproduced and the absence and returning time of the called subscriber, etc., are informed to the calling subscriber. When a presence selecting button is depressed, the CPU8 stops the tape 1 under the same condition upon receiving the CUE signal at the end of the OGM recorded on the tape 1. If an incoming call is made and the talking content is to be recorded, a talk recording button is depressed. Then the talking content is recorded on the tape 1.
