Patent JP-H02263051-A (JP)
Title: Refrigerating plant
Inventor: KITAUCHI HAJIME
IPC: F25B1/00
Filed: 1989-03-31
Abstract: PURPOSE:To prevent unnecessary operation of a protector due to a high pressure in a condenser by a method wherein the condenser and an accumulator are connected by a bypass pipe through a solenoid valve and opening and closing operations of the valve are controlled by detecting the refrigerant pressure and temp. at the outlet of the condenser. CONSTITUTION:A bypass pipe 7 connects the outlet of a condenser 2 and the inlet of an accumulator 5 through a solenoid valve 8. A pressure sensor 9 detects the refrigerant pressure at the outlet of the condenser 2 and a temp. sensor 10 detects the refrigerant temp. at the outlet of the condenser 2. At the time of a normal refrigerant cycle the valve 8 of a controller 11 is closed and then, a pressure value and temp. value are read by the sensors 9 and 10 respectively and a subcool value is calculated. Here, when more refrigerant than necessary is accumulated at the condenser 2, a high pressure value and a subcool value become large and then the controller 11 closes the valve 8. Then, refrigerant is recovered into the accumulator 5 due to the pressure difference between the condenser 2 inside and the accumulator 5 inside and the high pressure value and the subcool value become small and then the valve 8 is closed and the operation returns back to the normal one.

Title: Production of methylated melamine resin
Inventor: FUJISHIRO MUNEMARO
IPC: C08G12/32
Filed: 1995-04-07
Abstract: PURPOSE: To produce a methylated melamine resin comprising a precondensate of melamine with formaldehyde and methanol and used as a cross-linking agent for a coating resin in an industrially advantageous manner. CONSTITUTION: A methylated melamine resin is produced by reacting melamine with formaldehyde in a highly alkaline methanolic solution of a pH of 12 or above, separating the methanol by distillation during or after the reaction, adding methanol to the obtained intermediate product, and reacting the mixture under acidic conditions. Thus, a methylated melamine resin having an imino group content suitable from the viewpoint of the balance between film properties and workability and having low contents of methylene and methylol groups can be produced at good efficiency.

IPC: H03F3/45
Filed: 1979-06-30
Abstract: PURPOSE:To suppress the DC offset voltage signal level output from the output terminal at no signal to sufficiently small value, by providing the offset compensation resistor. CONSTITUTION:The DC voltage Vo at the output terminal OUT is Vo=R3/2beta, at no signal where the current gain is denoted as beta and the base resistance as R3 for the transistor Q2, by the presence of the offset compensation resistor R2, this means the voltage is at low level. By using the pinch resistance being the specific resistivity proportional to the current gain beta of the transistor Q1 for the ground resistor R1, desired effect of amplification can be obtained, even if dispersion is present in the current gain of npn transistors in the manufacturing process of monolithic IC.

Title: Dry etching method of nickel or nickel-containing alloy
Inventor: TAJI SHINICHI
IPC: C23F4/00
Filed: 1984-04-25
Abstract: PURPOSE:To perform dry etching with excellent dimentional accuracy and high selection ratio by using gaseous CO2 only or gaseous mixture which is essentially composed of gaseous CO2 and added with additional gas as etching gas. CONSTITUTION:The plasma of etching gas consisting of gaseous CO2 only or gaseous mixture whichis essentially composed of gaseous CO2 and added with additional gasses is brought into contact with the article to be etched of Ni or Ni-alloy and the desired part of the article to be etched is selectively etched. Since the etching velocity of the material other than Ni, for example, Si, SiO2 and Si3N4 in case of using gaseous CO2 is only about 1/10-1/30 of Ni, Ni can be selectively etched with high selection ratio. The selection ratio is changed into about 1-10 for photoresist but this is considered owing to be etched with oxygen atom generated by means of decomposition of gaseous CO2. To prevent it, graphite electrode is used to feed carbon from the electrode or gaseous CO2 added with max. about 20vol% gaseous H2 may be used.

Title: Fluid bearing spindle motor
Inventor: TOYOSHIMA HIROYOSHI
IPC: H02K5/124
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To increase service life and prevent contamination, by forming a seal, such as a viscous seal and a labyrinth seal, at one end of a dynamic pressure fluid bearing part, and combining an oil sump which prevents extra lubricating fluid from flowing out with the seal. SOLUTION: The combined use of the way which oil-repellent process or an oil-repellent agent is applied to a viscous seal part, and a contact angle is extended to prevent lubricating fluid from splashing can prevent leakage with higher effectiveness. The corner of the inner-periphery part of a thrust restraining plate 16 is chamfered positively, and a clearance 18 formed by chamfering is filled with lubricating fluid to give a cushioning effect which prevents extra fluid from leaking to the outside of a spindle motor. A space 19, formed out of the outer-periphery surface of a thrust plate 14 and the thrust restraining plate 16, is constructed for the purpose of the cushioning effect against fluid movement if a sleeve 12 is shocked, and serves as a relatively large space.  The space 19 has an oil retaining function of fluid, thus it is possible to increase the reliability of the spindle motor.
