Title: Semiconductor device and manufacture thereof
Inventor: NAKAMURA MAKOTO
IPC: H01L29/786
Filed: 1990-08-01
Abstract: PURPOSE:To reduce the occupying area ratio of an element isolating region to an integrated circuit device to the irreducible minimum and to enable component elements to approximate to each other so close as a photolithography technique permits by a method wherein an element region is formed of a semiconductor layer grown in the region surrounded with an insulator side wall on an insulating film. CONSTITUTION:A side wall SiO2 film 2 is deposited on a P-type Si base substrate 1, and the Sin. film 2 is patterned through photoetching so as to surround a predetermined element region. A growth mask SiO2 film 3 is formed on the predetermined element region, and a part of the film 3 is removed through anisotropic etching to provide an opening 4, whereby a (100) single crystal plane of the substrate 1 is exposed to serve as a seed of epitaxial growth. An Si layer 5 is grown inside the film 2 through a vapor growth method, whereby a single crystal Si layer is grown on the exposed single crystal plane and a polycrystalline Si layer is grown on the film 3. In succession, a source 6, a drain 7, a gate insulating film 8, and a gate 9 are formed on the layer 5, a wiring process is performed, and thus a circuit of high integration can be formed.

Title: Ion implantation and device therefor and semiconductor integrated circuit manufactured by using device
Inventor: UDA HIDE
IPC: H01L21/265
Filed: 1989-08-04
Abstract: PURPOSE:To obtain ion implantation which suppresses the annealing temperature to a low level by heating or cooling intentionally the substances to be treated during ion implantation according to the state of crystal defects which occur in the substances to be treated under ion implantation conditions. CONSTITUTION:For example, cooling mechanism 5 consisting of a plurality of cooling medium paths 5b in which cooling medium 5a, e.g. cooling water, liquid nitrogen or the like, flows is provided in the inside of a temperature control block 4. This device is constructed to prevent overheating of a semiconductor board W in such a way that heat, which is produced in the semiconductor board W by the incidence of ion beams 1 having high energy to the semiconductor board W, is taken away by the cooling medium 5a through the block 4 for controlling a temperature. As a natural consequence, therefore, the operation of heating mechanism 6 makes it possible to heat the semiconductor board W at a prescribed temperature that is higher than a shelf temperature. Then, the quantity of crystal defects remaining after ion implantation is decreased by allowing the recovery rate of the crystal defects as a result of heating to be superior to the development rate of the crystal defects due to incidence of the ion beams. This makes the heating temperature which is required for recovery of the crystal defects low during annealing.

Title: Multiple-room type air conditioner
Inventor: IGA NAOKI
IPC: F25B13/00
Filed: 1989-08-05
Abstract: PURPOSE:To eliminate the refrigerant noise generated from room apparatuses out of operation during heating operation by providing noise muffling fine tubes, which are so fine that they may not affect the capacity, on the upstream side of electronic expansion valves during heating operation. CONSTITUTION:When a room apparatus 35, for example, is brought in heating operation, a signal is output to an expansion valve controller 28 through a signal wire 38. The expansion valve controller 28 controls an electronic expansion valve 31 through a signal wire 31a while it detects a suction temperature sensor 25 and a saturation temperature sensor 26. On the other hand, as the other room apparatuses 36 and 37 are out of operation, the expansion valve controller 28 controls electronic expansion valves 29 and 30 through signal wires 29a and 30a so that the expansion valves 29 and 30 are opened a little. That is, the refrigerant in the room apparatuses 36 and 37 passes through the expansion valves 29 and 30 while its velocity is restricted under such a condition that noise muffling fine tubes 32 and 33 are opened to such an extent that they many not affect the capacity. At this time, the refrigerant flow is straightened by the noise muffling fine tubes 32 and 33 so that the refrigerant noise is prevented from being transmitted to the room apparatuses out of operation.

Title: Separate steering device
Inventor: WATANABE TOSHIYUKI
IPC: B62D113/00
Filed: 1999-07-16
Abstract: PROBLEM TO BE SOLVED: To determine whether an unsteerable condition, if any, is caused by mere tire-stuck or failure in an electric system, by detecting the conditions of a wheel and steering wheel, determining the stopping of the steering operation of a steering wheel during wheel operation, and determining whether the condition is normal or abnormal based on load current. SOLUTION: An unsteerable condition is determined if the steering angle variation βD of a steering wheel per a fixed time is smaller than the steering angle variation β determined by the rotational angle α of a wheel per a fixed time (S106). The load-current of a motor for a driving apparatus is detected (S108). The detected value ID of load current is compared with a stored stall current value IS and, in the case of ID>=IS, determination is taken as normal or mere tire-stuck (S114). On the other hand, in the case of ID<IS, comparison is taken as a current set value IR slightly lower than the ID and IS (S118) and, in the case of ID<IR, determination is taken as some abnormality such as failure in an electric system (S124).
Patent JP-H0252371-A (JP)
Title: Ozone removing device
Inventor: SETORIYAMA TAKESHI
IPC: G03G21/20
Filed: 1988-08-16
Abstract: PURPOSE:To minimize the concentration of ozone in discharged air and to prevent temperature rise in a device by dividing air flow into air flow in an enclosure air flow having a high concentration of ozone, and air flow having a low concentration of ozone and low temperature, and leading the air flows to their respective ozone removing parts each of which has different efficiency in ozone removal. CONSTITUTION:An ozone filter 1 is divided between upper and lower parts: a mesh part 1a is a coarse mesh layer, and a mesh part 1b is a fine mesh layer. Air flow A from an ozone producing source is led to the ozone removing part 1b which has high efficiency in ozone removal, and sent out of the device after ozone is completely removed. Air flow B from a heat source is led to the ozone removing part 1b which has a low efficiency in ozone removal. Since the loss of pressure at the time of passing through the ozone removing parts is small, heat is satisfactorily discharged from the enclosure without reducing the amount of exhaust air flow; at the same time, ozone which flows into the heat discharging side is also removed. Thus, the concentration of ozone in exhaust air is reduced and temperature rise in the device are prevented.
