Title: Semiconductor device and manufacture thereof
Inventor: KAWABUCHI YASUSHI
IPC: H01L21/3205
Filed: 1984-12-19
Abstract: PURPOSE:To realize an Al wiring equipped with moisture-proof and electromigration resistance by a method wherein an Al alloy is employed containing 0.1-0.2wt% of Pd or Pt and the Pd or Pt is precipitated as a simple substance or as a intermetallic compound. CONSTITUTION:The percentage of Pd should be 0.005-23% for corrosion resistance and not less than 0.1% for electromigration resistance. An alloy is therefore to be preferably composed of 0.1-2% of Pd, 0.1-3wt% of Si, and the rest Al. The alloy of Al-Pd or Al-Si-Pd is attached by spattering to a thermal Si oxide film. Next, solution annealing is accomplished by a 10-30min process at 480-530 deg.C, to be followed by a 20-60min process accomplished at 380-480 deg.C for the precipitation of Pd along the Al grain boundary. A 60-180min process is further accomplished at 330-380 deg.C for the precipitation of an Al-Pd intermetallic compound. By this method, a highly reliable Al alloy wiring is obtained. The same procesure is to be followed when Pt is used instead of Pd.

Title: Central cleaner
Inventor: MIYATA TERUYUKI
IPC: A47L5/38
Filed: 1990-10-05
Abstract: PURPOSE:To protect the deterioration of a power source circuit and to save the energy consumption by controlling the power source SW of the power source circuit with a control circuit having a low voltage power source through a voltage converter and energizing it only at the time of utilization. CONSTITUTION:A voltage is converted to a low voltage by a voltage converter 1 from a high voltage power source. The low voltage converted by the voltage converter 1 is always applied to a control circuit 2. When a handy switch 3 becomes a turn-on state, relay switches 6, 7 installed in a power source circuit 4 become a turn-on state by the command of the control circuit 2, a high voltage is applied to the power source circuit 4, and a motor 5 is driven through a motor control circuit 10. Also, when the handy switch 3 is set to a turn-off state, the relay switches 6, 7 become a turn-off state, and the high voltage power source becomes a turn-off state. Accordingly, it does not occur that a high voltage is always applied to the power source circuit, and the deterioration of electric parts such as a capacitor 12 used for the power source circuit can be prevented, and also, useless power consumption can be avoided.

Title: Semiconductor device and its manufacture
Inventor: TAKAHASHI TSUNEO
IPC: H01L29/165
Filed: 1986-11-11
Abstract: PURPOSE:To realize high-speed operation by a method wherein a Ge film whose mobility of an electron and a hole is bigger than that of Si is formed on an Si substrate and this Ge is used as a channel for a MOS-type transistor. CONSTITUTION:A Ge layer 6 is formed in a region which is located just under a gate electrode 4 and a gate insulating film 3 and is transformed into a channel. In addition, a source and a drain are constructed by a germanium layer 7 and an Si layer 8 doped with an impurity to give a p-type or an n-type. Because the mobility of germanium is by about two times bigger for an electron and by about 4.5 times bigger for a hole than that of Si, a MOS-type transistor, of the identical size, constructed by the Ge can operate by two times faster for an n-channel and by 4.5 times faster for a p-channel than in the case of the Si. As compared with the MOS-type transistor constructed by the Si, the characteristic of the p-channel is improved remarkably and is nearly equal to that of the n-channel; it is possible to greatly improve the characteristic of an integrated circuit of the CMOS structure.

Abstract: PURPOSE:To prevent the thickening of ink in the vicinity of an emitting orifice by holding the atmosphere of the capped part of a recording head to high humidity by providing an upwardly bent part to a tube and bringing the region on the side of a cap from the bent part to a state always wetted with ink. CONSTITUTION:The tube 442 connecting a cap part 420 to a pump 440 is bent upwardly in a vertical direction from the cap communication hole 442A to which the tube 442 is connected to be connected to the lower pump 440. After ink is sucked from an emitting orifice through the cap part 420, suction treatment is not performed or not sufficiently performed and a slight amount of the ink remains in the tube 442. That is, no entire ink flows in the pump by the presence of the bent part. The emitting orifice forming part 1A of a recording head 1 is held to a wet atmosphere in a capped state at the time of the interruption or stop of recording and the emitting orifice is protected from drying to make it possible to prevent clogging. At the time of long-term stop or at the OFF-time of a power supply, sufficient empty suction is performed so as not to leave the ink in the tube and the fixing of the ink in the tube is prevented.

Title: Signal recording and reproducing method to film
Inventor: BANSHO HIDENORI
IPC: G03B31/00
Filed: 1988-10-25
Abstract: PURPOSE:To record and reproduce the sound signal, the external synchronizing signal, etc., to a film with high fidelity by recording these signals on the film in the form of the interference fringes and then reproducing them. CONSTITUTION:At recording the recording light signal 6 emitted from a coherent light source 5 is made incident directly and vertically on a sound track part 4 of a film 1. At the same time, the recording light signal 7 reflected by a mirror 8 is made incident at an incident angle theta against the signal 6. The light interference fringes 23 are produced at the part 4 by both signals 6 and 7. These fringes 23 are exposed to the light and recorded. At reproduction the reproduction light 11 emitted continuously from the light source 5 is made incident on the part 4 at an incident angle alpha. When the light 11 is made incident on the part of the fringes 23 of the part 4, the fringes 23 function as a diffraction grating of a pitch (p). Thus it is possible to obtain the reproduction signal of the extremely high quality with no influence of the film flatness.

Filed: 1991-09-18
Abstract: PURPOSE:To obtain images with high resolution and to improve identification accuracy by correcting the identified result of an objective block outputted from an in-block attribute identifying means corresponding to the changed value of a counter. CONSTITUTION:An image is divided into plural blocks and corresponding to the respective blocks, plural counters are provided. The value of the counter corresponding to the object block is changed by a counter changing device 4 corresponding to the identified results of peripheral blocks stored in an attribute identified result memory 6, and the identified result of the object block outputted by an in-block attribute identifying device 3 is corrected by an attribute changing device 5 corresponding to the changed value of the counter. Namely, since the identification is executed for the unit of the block, the images with the high resolution are obtained and since the identified result is corrected based on the identified results of the peripheral blocks, the identification accuracy is improved. Further, since it is enough only to store the identified results of peripheral blocks, memory capacity is decreased and cost is reduced.
