Title: Projection exposure
Inventor: UMAGOME NOBUTAKA
IPC: H01L21/027
Filed: 1987-10-09
Abstract: PURPOSE:To eliminate the need for precise structure for vertically moving a substrate, etc., such as a wafer mechanically, and to realize a static multiple exposure method operating at high speed by shifting the best imaging surface of an original picture pattern in the direction of an optical axis during exposure operation by utilizing the optical characteristics of a projection optical system. CONSTITUTION:Light from an illumination system (including a light source, a fly eye lens, etc.), for exposure reaches a main condenser lens 3 through a shutter 2, and lights a reticle R having an original picture pattern by uniform illuminance. The image of the original picture pattern is image-formed onto a wafer W by a projection lens PL. A specified space 6 in the projection lens PL is hermetically sealed from the outside, and internal pressure is controlled by a first pressure control system 7. A second pressure control system 8 changes the pressure of the space 6 in the projection lens PL at high speed within a specified range. The pressure in the space 6 is changed during exposure operation in which the shutter 2 is opened. A main control system 9 collectively controls a device. The space 6 in the projection lens PL is selected optimally so that the variation of projection magnification is minimized to the alteration of a focal position generated by pressure control.

Title: Heat pump type hot water apparatus
Inventor: SAKAKIBARA HISASUKE
IPC: F24D17/02
Filed: 1999-09-09
Abstract: PROBLEM TO BE SOLVED: To provide a heat pump type hot water apparatus wherein heat losses due to heat dissipation from a hot-water storage tank can be reduced. SOLUTION: The heat pump type hot water apparatus 1 uses a heat pump cycle C as a heating means for heating water to be fed to the water apparatus wherein CO2 of low critical temperature is used as a refrigerant. In a control device to control the operation of the apparatus 1, a calendar clock which can count time, for example, in months is included, and a target hot-water storage temperature is set in the clock beforehand in each season, which is decided by the clock. Since usage of hot water in summer is larger than in winter, through a year, the target temperature is set at a low temperature (e.g. 65 deg.C) in summer and at higher temperature (e.g. 90 deg.C) in winter.  The control device controls the delivery flow rate of a water pump 4 and the operation condition (opening of an expansion valve 8) of the cycle C so that the temperature of water to be fed to the apparatus 1 becomes equal to the target hot-water storage temperature.

Title: Carbon-coating film
Inventor: MIYANAGA SHOJI
IPC: C30B30/04
Filed: 1999-09-10
Abstract: PROBLEM TO BE SOLVED: To form a thin film having high adhesion strength to the surface where the film is formed, by applying microwaves having at least first and second square pulse forms with different waveheight to generate plasma of the reaction gas. SOLUTION: A CVD system which produces high density plasma by the interaction of pulsed microwaves and a magnetic field is used. By controlling the pulses in such a manner that first peaks are higher than second peaks and the second peaks are 5/6 of the first peaks, SP3 bonds which are preferable for the formation of a hard carbon film are increased while SP2 bonds having weak bonding force are removed. In order to produce and keep the high density plasma at high pressure, electron cyclotron resonance is first produced at low vacuum as 1×10-4 to 1×10-5 Torr in the space with a column, and then the gas is introduced. The plasma state is maintained while pressure is changed to high pressure to 0.03 to 30 Torr to change the product gas into high density to form a film.  For example, when diamond is formed, columnar grains 29 of diamond having large particles are grown on a substrate 10.

IPC: B66B1/36
Filed: 1987-10-14
Abstract: PURPOSE: To eliminate the stumbling accident due to a difference in level while restricting a landing error within an allowable range by providing a means for delaying a start of a brake means at the time of operating an elevator immediately after the condition that the elevator is stopped for a long time and for delaying the electric supply cutting-off timing to a magnet coil of a brake device so as to shorten the braking action time. CONSTITUTION: A timer T detects that an elevator is continuously stopped while exceeding the predetermined time. At the time of restarting the operation of the stopped elevator, a brake delay means (formed of a contact T1 , a relay A, a contact A2 , a time relay TM and a contact TM1 ) is driven on the basis of the detecting signal of the timer. Start of the operation of the brake means is delayed by the brake delay means, and electric supply cutting-off timing to a magnet coil MB of a magnet type brake device is delayed, and the brake operating time of the brake means is shortened. As a result, at the time of operating the elevator immediately after the long-time stop, a landing error is restricted within the allowable range, and a stumbling accident due to a difference in level between a car floor and a landing floor is prevented.
