Title: Package of semiconductor integrated circuit
Inventor: YAMAZAKI HIROETSU
IPC: H01L23/32
Filed: 1983-01-17
Abstract: PURPOSE:To facilitate mount to a substrate and dismount therefrom by using semiconductor IC package consisting of a fixture having a film carrier and a package mounting means. CONSTITUTION:The semiconductor IC24 is fixed to the fixture 30 with die bond 25, and an insulation film 2 constituting the film carrier is fixed with adhesive 29. Leads 27 of the film carrier which are connected to the semiconductor IC24 pass outside the fixture and extend to the opposite side of the mounting position for the semiconductor IC, then becoming pads 28. Further, the fixture 30 has a fixed rod 31 whose tip is screw form on the surface opposite to the mounting position for the semiconductor IC. Then, the semiconductor IC package is fixed to a substrate by means of the fixed rod 31 passing through a hole 37 bored in the substrate, a check plate 34, and a clamping screw for the fixed rod. The pads 28 of the semiconductor IC package and the wiring pad 33 of the substrate are pressed by a projection 36 coming out of the fixture and then electrically connected. Since the semiconductor IC package and the substrate are only pressure-welded in this manner, mounting and dismounting are easy.

Title: Machining method of ceramics
Inventor: NAKAGAWA MOROO
IPC: B23H1/00
Filed: 1985-01-18
Abstract: PURPOSE:To enable an insulating ceramic to be electric discharge machined, by providing a conductive firm on a surface of the insulating ceramic forming its cut surface conductive. CONSTITUTION:An insulating ceramic 1 forms its cut surface conductive, and the ceramic 1, providing on its surface a conductive film 2, performs electric discharge machining in the air by an electrode 3. When the machining is started, an electric discharge, being generated between the electrode 3 and the conductive film 2, performs machining, and as the machining advances a machined portion of the insulating ceramic 1 is successively formed conductive, enabling further electric discharge machining to be performed. The insulating ceramic, forming its cut surface conductive, uses, for instance, silicon carbide, and a part in the vicinity of a machined surface is formed conductive by carbon adhering to the cut surface. When the machining is performed in liquid, the liquid, removing the carbon, prevents the ceramic from being formed conductive.

Title: Digital-analog converter
Inventor: KASAHARA MASUMI
IPC: H03M1/66
Filed: 1987-01-16
Abstract: PURPOSE:To form the titled converter into the semiconductor integrated circuit with a simple state including a low pass filter by using a delay processing by a digital delay circuit and an addition processing by an analog adder circuit so as to apply filter processing. CONSTITUTION:The digital delay circuit 2 consists of latch circuits and transmits a digital signal Din with a delay of one or two clocks. The analog adder circuit 3 add analog outputs in terms of currents outputted from D/A converters 11, 12 respectively and the added analog signal is extracted as a voltage signal from a common connecting point. A kind of filter processing is applied by the delay processing of the digital delay circuit 2 and the adder processing of the analog adder circuit 3. Thus, the reflected noise in the analog signal obtained by D/A conversion is eliminated efficiently by a simple low pass filter 4 comprising a resistor Rt and a capacitor Ct only.

Title: Disc rotor
Inventor: SAKAI TAKASHI
IPC: F16D65/00
Filed: 1982-01-20
Abstract: PURPOSE:To lower the level of noise caused by disc rotor vibration in braking by forming in a disc rotor, a lot of resonance spaces which open on its side surface. CONSTITUTION:Both side surfaces of a disc rotor 1 are provided with a lot of resonance spaces 6, which are narrow at their entrances 6a but wide at their interiors 6b. When a sound wave comes in or goes out from these resonance spaces 6 passing through the entrances 6a, the sound is damped owing to the resonance effect. Thus even if a noise-level sound wave, occurs in braking, being caused by disc rotor vibration due to friction between a pad lining and the disc rotor, this sound wave is damped by the resonance spaces 6 so that it may not grow into a large noise.

IPC: G11B5/027
Filed: 1984-01-17
Abstract: PURPOSE:To attain the automatic level control of a sound signal and also to increase the controlling speed by comparing the level of a reproduced reference signal with a proper level read out of a memory by a level detector and controlling the level of a reproduction signal or a record signal. CONSTITUTION:A microcomputer 28 supplies a reference signal to an input terminal 1 to secure a recording mode. Then a digital reference signal is supplied to a level detector 38 via a switch circuit 30, VCAs 31 and 32, an A/D converter 33 and a switch circuit 37 respectively. Thus the value of the reference signal (level information) is detected and supplied to a register B via a common bus 29. Then the computer 28 decides whether the value of the register B is equal to a proper level A or not. When the register B has the value extremely approximate to the level A, the gain control information of the VCA31 of the detector 38 is applied to a memory 39 from the detector 38 through the bus 29 and stored.

Title: Method of treating drain liquid containing inorganic medicine and organic substance
Inventor: IBUKA HIDEO
IPC: F23G7/04
Filed: 1978-01-23
Abstract: PURPOSE: To restrict production of nitrogen oxide at burning time of drain liquid by dividing and feeding combustion air into upper and lower portions in a furnace and further dividing air necessary for completely burning unburned content at the upper portion in the furnace into a plurality of stages.  
     CONSTITUTION: Drain liquid containing inorganic medicine and organic substance is injected from a drain liquid burner 2 into a furnace 1 and is partially burnt at the organic content in the liquid by secondary air 12 to allow water content in the liquid to be evaporated by the heat. Inorganic medicine in the liquid is accumulated as ash floor 5 on a grate and exhausted out of the furnace from a medicine outlet hole 6 to be thus recovered. In the meantime, inorganic medicine is reduced under insufficient oxygen atmosphere by the heat partially burnt of the organic content by primary air 11 and thus molten. The residual organic content is completely burnt by the air fed upon division into two stages of the tertiary and quartic airs 13 and 14. Thus, peak temperature is reduced to approx. 1200°C.

Abstract: PROBLEM TO BE SOLVED: To specify a caller by changing the tone of a ringer sound based on the telephone number of the caller. SOLUTION: This telephone set is provided with a transmission/reception part 2 for receiving the telephone number of the caller, SIM 3 for registering telephone numbers, RAM 34 storing sound numbers, ROM 4 storing sound numbers and tone data, CPU 5 and speaker 6. At the time of call incoming, a telephone number TN of the caller is extracted by a telephone number extracting part 51 in the CPU 5, and the telephone number TN is compared with a telephone number read out of the SIM 3 by a comparing part 53. When these telephone numbers are coincident, a selecting part 54 selects tone data corresponding to the sound number of that telephone number out of the ROM 4 and outputs these data to the speaker 6. Thus, the ringer sound of tone specifying the caller is rung from the speaker 6.  Besides, when the telephone number TN is not coincident with the telephone number read out of the SIM 3, a usual ringer sound is rung from the speaker 6.
