Title: Heating device and semiconductor equipment wherein the heating device is employed
Inventor: YOSHIE KEIZABURO
IPC: H01L21/205
Filed: 1990-06-18
Abstract: PURPOSE:To make it possible to regulate a temperature only by a gas pressure by installing containers to store gas the temperature of which is regulated by regulating a gas pressure adjacently to a material to be heated. CONSTITUTION:To heat a wafer 12, gas is used, the temperature of which is regulated by regulating the pressure. Stainless-made containers 7a-7c are installed around a chamber 6 to store such temperature-regulated vapor with no space left over between the containers. After putting the wafer 12 inside the chamber 6, gas is supplied to each of turbocompressors 13a-13c from a gas supply vessel 15. The pressure of the gas is made, for example, about 300kg/cm<2> by the turbocompressors 13a-13c. As a result, the temperature of the gas rises to 400 deg.C according to the gas pressure. When the temperature of the wager 12 get steadied, reactive gas is brought in into the inside of the chamber 6 to keep the inside of the chamber at the specified pressure. This condition is kept for the specified span of time to form a polysilicon film of the specified thickness on the wafer 12.

Patent JP-H04359694-A (JP)
Title: Tension controller
Inventor: FUJIHIRA KAZUYA
IPC: H02P21/34
Filed: 1991-06-04
Abstract: PURPOSE:To provide a highly accurate tension controller which can exhibits high control response with no possibility of cutting the material even when the tension varies due to disturbance. CONSTITUTION:A control parameter setting circuit 20 varies the proportional integration constant for determining the gain of tension feedback control according to a detected value of tension and if thus detected tension of material is lower than a preset value, the proportional integration constant is switched to a value lower than a normal value based on an output from a detecting circuit 19. When the winding of material slacks due to disturbance, gain of feedback control lowers and abrupt rising of tension due to inertia is suppressed. Consequently, there is no possibility of cutting off the material. When the material is wound with no slack, the gain of feedback control is high and sufficiently high control response is exhibited with no possibility of deteriorating the control accuracy.

Title: Method for evaluating content of sodium in glass substrate for photomask
Inventor: YAMANE HIROYUKI
IPC: G01N27/04
Filed: 1982-09-16
Abstract: PURPOSE:To enable the easy non-destructive evaluation of the content of sodium in a glass substrate for a photomask in the stage of manufacture as well by forming chromium film layers on one side of both surface sides of the glass substrate to form a chromium blank, and measuring the specific resistance of the glass substrate with both chromium film layers as electrodes. CONSTITUTION:A novel chromium blank construction is obtd, by forming a chromium film on the rear of a chromium blank. A chromium film 2 and the chromium film 4 serve respectively as the electrodes on the front and rear of a glass substrate 1 with such novel chromium blank construction. The specific resistance of the substrate 1 can be measured by an insulation resistance meter 5 through the two electrodes. Sodium ions determine dominantly the electrical conductivity of the glass. Therefore, if the specific resistance of the substrate 1 is measured as mentioned above, the content of sodium (in the substrate 1) corresponding to said value is evaluated from the measured value.

Title: Chilling and heating apparatus
Inventor: KATO HARUHIKO
IPC: B60H1/00
Filed: 1988-06-28
Abstract: PURPOSE:To achieve a simple air-conditioning structure capable of heating a room irrespective of ambient temperature by providing a casing receiving an outdoor-installed heat exchanger and radiator and having openings which is opened in chilling mode and closed in heating mode. CONSTITUTION:In heating operation mode, first and second openings 13 and 14 of a case 12 are closed. Air in the case 12 is circulated in the direction indicated by the arrow B through an exterior heat exchanger 10 and an oil cooler 22 by means of a fan 21. When an electromagnetic valve 24 is turned on, oil is fed to the oil cooler and heat of the oil in the oil cooler 22 is radiated on the upstream side of the exterior heat exchanger 10. Air heated by heat radiation of the oil cooler is subjected to heat exchange with the exterior heat exchanger 10 during circulation in the direction indicated by arrow B. This permits evaporation of a cooling medium flowing through the heat exchanger 10 irrespective of ambient temperature. Therefore, in the case of low ambient temperature, lowering of a room heating capacity is prevented.
