Patent JP-H0411621-A (JP)
Title: Production of novolac phenol resin for shell molding
Inventor: SUZUKI NORIAKI
IPC: C08G8/00
Filed: 1990-04-27
Abstract: PURPOSE:To obtain the title resin which does not emit any malodor even when heated to a high temperature by reacting a phenol with a formaldehyde while adding an acid catalyst at intervals to the reaction system in portions and dehydrating the reaction product by heating in a vacuum in two specified stages. CONSTITUTION:A phenol is reacted with a formaldehyde while an acid catalyst (e.g. oxalic acid) is added to the reaction system at intervals in portions. The reaction mixture is subjected to primary dehydration by heating to 120 deg.C in a vacuum of 100-150Torr. When the temperature reaches 120 deg.C, it is then subjected to secondary dehydration by heating to 230 deg.C in a vacuum of 60Torr or below. In this way, a novolac phenol resin for shell molding can be obtained. Because the obtained phenolic resin has a free phenol content of 1wt.% or below, it does not emit any malodor even when it is used as a binder for the shell molding process and molded at a high temperature.

Title: Tension sensor and calibration method therefor
Inventor: HIRAI KAZUYASU
IPC: D02G1/04
Filed: 1993-04-16
Abstract: PURPOSE:To easy calibrate the output of a pickup in a short time by determining the relationship between the thread tension and the output voltage based on the first and second reference tensions and each output power at that time. CONSTITUTION:When a first reference tension is set in no-load state and a second reference tension is set in load state of 100g, for example, output voltages V0, V1 from a rotational angle detector 4 in a sensor body 1 are temporarily stored in the memory circuits 24a, 24b in a feedback controller 20 through push switches SW1, SW2. An operating circuit 25 then determines thread tension-output voltage characteristics representative of the relationship between the stored voltages V0, V1 and the thread tension. Thread tension T for an output Vt from the detector 4 is then calculated according to a formula; T= (second reference tension-first reference tension) X (Vt-V0)/(V1-V0) + first reference tension. Nip power of a nip twister (belt type temporary twister) is then regulated through an air controller 21.

Title: Address generating device
Inventor: MASUHAMA KAZUO
IPC: G06F15/16
Filed: 1992-04-08
Abstract: PURPOSE:To prevent a processor from being reduced at its processing capacity and to improve a transfer speed by forming buffer addresses while keeping the compatibility of port management between H/W and S/W even at the time of transferring continuous messages. CONSTITUTION:A port specification address storing table 32 outputs a port specification address 36 to be data corresponding to a port address 35 to a buffer address forming part 33. The generating part 33 adds a current address 37 outputted from a receiving FIFO 39 to the address 36 outputted from the table 32 and outputs the added result to a receiving buffer 13 as a buffer address 38. Consequently memory access information 17 outputted from the FIFO 39 is stored in a memory block of the buffer 13 which is specified by the buffer address 38 applied to the buffer 13.
Patent JP-H05315842-A (JP)
Title: Mixer circuit
Inventor: IZUMI OSAMU
IPC: H03D7/12
Filed: 1992-05-07
Abstract: PURPOSE:To improve the separation between a local signal and a transmission signal by connecting two resistors whose resistance is equal to each other in series, giving a positive and a negative potential whose absolute value is equal to each other to both terminals and applying a bias voltage at a connecting point to a gate of a 2nd FET. CONSTITUTION:A potential VG2S=OV is impressed to a gate of a FETF2 from a common connecting point A. A current flows from the connecting point A to resistors R1A, R1B connected in series between DC bias voltages +VDD and -VGG to provide OV to the connecting point forcibly. Since a current flowing to a R1 is larger than an input current to a gate of the FETF2, the fluctuation of the potential due to the input current is not almost caused, and a DC level is stable and a OV level is obtained even with a large amplitude input. As a result, when the mixer circuit consists of FETs, the leakage of a local signal is cancelled and the isolation characteristic between the local signal and the transmission signal and the mixer characteristic at a microwave band are improved.

Abstract: PROBLEM TO BE SOLVED: To enhance the gradation of finished image and to obtain an image exhibiting a good quality feeling by forming an image by developing using an electrostatic latent image developing toner comprising plural yellow, magenta and cyan toners, each being different in concentration. SOLUTION: An image is formed by developing using an electrostatic latent image developing toner comprising plural yellow(Y), magenta(M) and cyan(S) toners, each being different in concentration. The electrostatic latent image developing toner, having the minimum concentration in each yellow(Y), magenta(M) and cyan(S) toner, is produced by using, as a colorant, a sublimable or heat-diffusible dye having a solubility to methyl ethyl ketone of >=0.2 g/100 cc (25 deg.C) and a molecular weight of <=600. This sublimable or heat-diffusible dye has such a property that when it is fixed by generally utilized heat fixing method (120 to 180 deg.C), at least a potion of the dye in the toner particles diffuses into a space between toner particles or an image-accepting layer coated on the toner particles and the recording material at the time of fixing. Thereby, the gradation of the finished image is enhanced and the image exhibiting a good quality feeling can be obtained.

Filed: 1997-04-17
Abstract: PROBLEM TO BE SOLVED: To prevent a thermosiphon from occurring by providing a partitioning wall whose lower edge is dipped to an area below a cooling material free surface between an outer liner and an inner liner of the upper part of an inner annulus part and preventing a heated rising flow from flowing into a submergence weir part. SOLUTION: A cylindrical outer liner 42 and inner liner 43 are arranged concentrically. An outer annulus part 48 is formed between a reactor container 10 and the outer liner 42 and an inner annulus part 49 is formed between the outer liner 42 and the inner liner 43, thus enabling the upper edge part of the outer liner to submerge below a free liquid surface. A low-temperature cooling material flows in from a flow hole 44 and rises, flows down the inner annulus part 49, passes the flow hole 46, and flows into an upper plenum 24. The flow that rises after being heated on the outer surface of the inner liner 43 cannot reach the free liquid surface between a partitioning wall 50 and the reactor container 10 and circulates so that it descends while being accompanied by the descending flow of the submergence weir (outer liner 42) part.  Neither thermo fin nor temperature stratification occurs.
