Title: Manufacture of semiconductor device
Inventor: IRINO KIYOSHI
IPC: H01L21/304
Filed: 1989-11-21
Abstract: PURPOSE:To prevent the contamination of substrates caused by chemicals which have permeated into 'Teflon(R)', and enable the washing of substrates retained by a 'Teflon(R)' basket, by a method wherein, before the substrates for which chemical treatment is finished are dried, the substrates are dipped in warm water at 70-100 deg.C, together with the 'Teflon(R)' basket. CONSTITUTION:When substrates 6 retained by a 'Teflon(R)' basket 5 are washed, the substrates 6 are dipped in warm water at 70-100 deg.C just before drying. Thereby chemicals which have permeated into the 'Teflon(R)' basket is made to dissolve into the warm water, and prevent from oozing again at the time of drying in the subsequent process and after drying. In the case of spin drying, the warm water at 70-100 deg.C is used. In the case of IPA drying, the warm water at 85-100 deg.C is used. Thereby the contamination of substrates caused by chemicals which have permeated into the 'Teflon(R)' can be prevented, and the washing of the substrates retained by the 'Teflon(R)' basket is enabled. The generation of dust during the washing of substrates can be restrained, and the contamination caused by chemicals is excluded, so that the reliability of a device and the yield of manufacture can be improved.

Title: Pulse modulation system and d/a converter
Inventor: TANI YASUNORI
IPC: H03M1/86
Filed: 1991-11-19
Abstract: PURPOSE:To ensure the linearity of output power by outputting an AND output between a pulse width modulation signal having processing width synchronously with a reference clock and a pulse train with a prescribed width synchronously with a reference clock. CONSTITUTION:An AND signal between pulse width modulation signals b1-b5 having a prescribed width synchronously with a reference clock (a) in response to an inputted digital signal and a pulse train C with a prescribed width synchronously with the reference clock (a) is outputted. Moreover, an AND signal between the pulse width modulation signals b1-b5 having a prescribed width synchronously with the reference clock (a) in response to the inputted digital signal whose power center position is synchronized and the pulse train C with a prescribed width synchronously with the reference clock (a) is outputted. The number of times of pulse rising and falling is made proportional to the pulse width by converting modulation outputs d1-d5 into pulses with a prescribed width whose number is proportional to the width of the pulse in this way. Thus, the linearity of output power is secured and lots of output gradations are attained.

Title: Air conditioner
Inventor: YAMAMOTO MASAFUMI
IPC: F24F5/00
Filed: 1990-11-07
Abstract: PURPOSE:To make it possible to obtain a high level of air conditioning performance by changing/setting an axial relative position of a fan rotor and fan guide in conformity with in-equipment resistance. CONSTITUTION:During an operating condition having a large air capacity or more particularly under regular operating condition where there is no frost adhered to a heat transfer tube of a heat exchanger 3 with low in-equipment resistance, an rotor 5 is set to the maximum sweep back position. During an operation condition having a small air capacity or more specifically, under an operating condition where frost is produced and adhered to the heat transfer tube which has resulted in a rise in the in-equipment resistance, the rotor 5 is set to the maximum projecting position. This construction makes it possible to operate a propeller-driven fan 4 with higher static pressure under either operating condition by changing/setting the relative positions of the fan rotor 5 and a fan guide 7. It is, therefore, possible to obtain a high level of air conditioning efficiency in a wider operation area.

Title: Die heating device and method for molding resin using said device
Inventor: SADANO MEGUMI
IPC: B29C45/73
Filed: 1992-10-16
Abstract: PURPOSE:To make it possible to do rapid heating by burying an electromagnetic inductive heater toward a cavity surface in a recessed part for storage formed at any position upto a position adjacent to the rear of the cavity surface. CONSTITUTION:A cavity surface 2 adjacent to a spot where an electromagnetic inductive heater 4 is provided, is preheated by applying an alternating current to this electromagnetic inductive heater 4. A drop in temperature due to the opening of a die 1 and cooling for taking a molded product from the die has only to be made up for by the value of the drop in preheating. In addition, a spot selected as one necessary for heating is locally heated instead of the preheating of the entire cavity surface 2, so that it is possible to heat the spot upto a required temperature level in a short time by AC application. Especially if an alternating current is applied under control to the electromagnetic inductive heater 4 based on the reading obtained by a temperature detector installed near the cavity surface 2 which is preheated, the preheating can be automatically controlled. Consequently, the existing equipment can be easily modified for improvement and investment in the modification can be minimized.

Filed: 1990-11-13
Abstract: PURPOSE:To reduce a bit error rate of a reception signal by compensating or not compensation a signal distortion in the reception signal by an equalizing means depending on a reception electric field strength of a received digital modulation signal. CONSTITUTION:When the reception state of a digital modulation wave is excellent and the reception electric field strength is strong, demodulation by delay detection is implemented at a delay detection circuit 111 not through an equalizer 110.

When the reception state of the digital modulation wave is not excellent and the reception electric field strength is weak, the signal distortion included in the reception signal is reduced by the equalizer 110 and the demodulation by delay detection is implemented by the delay detection circuit 111. Thus, the bit error rate of the reception signal is properly reduced.

Title: Heat insulation structure of gas turbine engine
Inventor: YONEZAWA KATSUO
IPC: F02C7/18
Filed: 1997-11-06
Abstract: PROBLEM TO BE SOLVED: To improve the durability of the combustion cylinder against a high- pressure load on this cylinder by reducing the pressure of compressed air exerted on the outside of the combustion cylinder to reduce the pressure load on this cylinder. SOLUTION: Part of compressed air for cooling the combustion cylinder 1 is introduced to flow along the outside of this cylinder 1 into a gap 7, approximately the same as a combustion gas flowing along the outside of the cylinder 1. Part of the air in the gap 7 flows into entrance hole 9 gaps 8 of a heat insulated board 6 to flow along the cylinder 1 and the remains flow along this board 6 in the gap 7. The compressed air flowing from the hole 9 lowers the pressure in the gaps 8 to reduce the difference between the pressure Po of the compressed air exerted from outside on the wall of the combustion cylinder 1 and pressure Pg of the combustion gas exerted from inside on the wall of this cylinder 1, thus lowering the pressure load of the combustion gas on the combustion cylinder 1 wall. This improves the durability of the cylinder 1.
