Title: Automatic method for controlling number of boilers
Inventor: MIYAGAWA YASUHIRO
IPC: F22B35/00
Filed: 1989-09-20
Abstract: PURPOSE:To improve the response characteristic to a variation of load by increasing or decreasing the number of boilers in operation which are operating from the value of the sum of the amount of steam increased or decreased to a required amount and the amount of steam increased or decreased as required to maintain the internal pressure of a steam header to a target pressure. CONSTITUTION:The steam quantity Q1 generated in boilers 1 is calculated for each boiler, and then their steam quantities are totaled. Here, supposing that the pressure gradient in the steam header is: dPn/dt= P, the actual steam quantity Q0 that is used in equipment which employs steam is shown as: Q0=(1-f1( P))XQ1. Here, f18( P) is a correction coefficient. And the steam quantity that is to be increased or decreased is the sum of the steam quantity Q2 increased or decreased for the required steam quantity Q0 and the steam quantity Q3 increased or decreased as required to maintain the internal pressure of a steam header 2 to a target pressure Pt, and the steam quantity Q2 increased or decreased is: Q2=Q0-Q1=-f1( P)XQ1, and the steam quantity Q3 increased or decreased is: Q3=f2(Q1)X(Pt-Pn). Here, f2(Q1) is a correction coefficient. The steam quantity, (Q2+Q3) that is to be increased or decreased is, therefore, expressed as follows: Q2+Q3=-f1( P)XQ1+f2(Q1)X(Pt- Pn), and the number of the boilers 1 in operation is controlled by this value.

Title: Air conditioner drain pan
Inventor: NATORI HITOSHI
IPC: F24F13/22
Filed: 1991-09-25
Abstract: PURPOSE:To obtain a drain pan which is excellent in oil resistance and favorable in mechanical strength by using a polyvinylidene chloride foam. CONSTITUTION:A polyvinylidene chloride foam, which is excellent in oil resistance and capable of die-molding, and what is more, provides high mechanical strength, is used for a drain pan 1 of an air conditioner. The polyvinylidene chloride foam is obtained by die-molding foaming agent-impregnated beads into non-crystallizable copolymerizate. The non-crystallizable copolymerizate is a copolymer which comprises vinylidene chloride of 30wt.%-85wt.% and a copolymerizable monomer of 15wt.%-70wt.%. It is, therefore, possible to obtain strong thin-walled moldings since the drain is high both in compression strength and bending strength and maintain its configuration for a long time since it is high in oil resistance.

Title: Semiconductor device
Inventor: SHIMIZU KAZUO
IPC: H01L23/34
Filed: 1984-11-22
Abstract: PURPOSE:To make it possible to perform high density mounting on a printed board and the like and to facilitate standardization of the printed board characterized by excellent heat radiation and moisture resistance and improved mechanical strength, by splitting the tip part of each tab suspending lead into a plurality of parts, and forming the tip parts in the approximately same configuration as other outer connecting terminals. CONSTITUTION:A pair of tab suspending leads 3 and 4 is formed at facing positions of a tab 1. A semiconductor chip 5 is attached on the upper part of the tab 1. The tab suspending leads 3 and 4 are formed in the same structure. The tab suspending lead 3 is split into terminal parts 3a and 3b in a package. Said tip parts are formed in the approximately same configuration as other outer connecting terminals 21-44. Since the terminals 3a and 3b are separated, heat is separated into the terminal parts 3a and 3b when the heat of the semiconductor chip 5 is transferred through the tab suspending leads 3 and 4 and radiated. Therefore, the heat generated by the semiconductor chip 5 is absorbed by a wiring pattern 51 formed on a printed board 50 through the tab 1, the tab suspending leads 3 and 4 and each of the terminal parts 3a and 4a. The heat radiation of the semiconductor chip 5 is quickly carried out.

Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To facilitate heat correction without using a special circuit by converting the quantity of heat stored in a thermal head to stored heat gradation data, subtracting the stored heat gradation data from printing gradation data of print data and driving a thermal head according to the obtained subtracted gradation data. SOLUTION: A correction operation circuit 2 which inputs a gradation data x'Nj for every dot of lines to be printed reads out a corresponding quantity of stored heat T(N) immediately before the start of power supply from a stored heat quantity memory part 3, subtracts data T(N) from the gradation data x'Nj and obtains a gradation data xNj after corrected. When the gradation data xNj is smaller than a limit gradation value, the limit gradation value is set as the gradation data after corrected. The operation result of the operation circuit 2 is sent as print data to a thermal head to print the data. At the same time, a stored heat operation circuit 4 obtains a new stored heat by the gradation data xNj and a correction quantity operation circuit 5 calculates a quantity of heat to be stored for a next line.

Title: Load driving device
Inventor: SAWADA YASUYOSHI
IPC: H03K17/567
Filed: 1992-09-17
Abstract: PURPOSE:To attain the drive of the load by eliminating the change of the switching speed due to the change of the gate capacity of a power MOSFET and regenerating accurately the duty of the pulse signal received from a load controller. CONSTITUTION:A time constant circuit 12 decides the rising and falling times of a pulse signal consisting of the output of a microcomputer of a load controller 25, etc. A comparator 13 applies the conduction/cut-off control to the transistors TR1 and TR2 of a drive circuit 14 so as to secure the coincidence between the output of the circuit 12 and the gate voltage of the MOSFET 15. As a result, the gate current varies to the change of a gate capacity 30 and therefore the switching speed of the MOSFET 15 never changes. Thus a load 16 can be accurately driven in accordance with the duty of the pulse signal. Furthermore the switching timing can be optionally set with the change of the current capacity of both current sources 22 and 23.
