Title: Water-soluble ink for ink jet recording
Inventor: MUKAI HIROSHI
IPC: C09D11/326
Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To obtain a water-soluble ink made proof against a failure in delivering from nozzles due to air bubbles entering them at a temperature higher than room temperature by selecting an ink comprising water, a water-soluble dye, a surfactant and a water-soluble organic solvent and having a specified advancing contact angle with respect to a silicon dioxide layer formed on a silicone surface. SOLUTION: Water is mixed with a water-soluble organic solvent such as a monohydric alcohol, a polyhydric alcohol or a nitrogenous compound, a water- soluble dye and a mixture comprising 3-5wt.% acetylenediol surfactant and 0.01-0.02wt.% polyoxyethylene alkyl phenyl ether surfactant to obtain an ink for ink jet recording, having an advancing contact angle of 0-20 deg. with respect to a silicon dioxide layer formed on a silicone surface. This ink does not suffer the problem that air bubbles enter nozzles under an environment of temperature from room temperature to 45 deg.C and is therefore made proof against a failure in delivering from the nozzles.

Title: Radio receiver
Inventor: NOJIRI KOICHI
IPC: H04B1/10
Filed: 1989-12-29
Abstract: PURPOSE:To demodulate a reception signal in a system with no interfering radio wave to another radio receiver from an antenna by utilizing a mixing circuit using a local oscillation signal at a frequency sufficiently apart from the frequency of the reception signal at a pre-stage close to the antenna. CONSTITUTION:The mixing circuit 24 being a pre-stage frequency conversion circuit mixes a signal of 210MHz being sufficiently apart from a signal whose center frequency is 280MHz with the signal. Moreover, a band pass filter 23 passes through only a signal with a sufficiently narrow band around the frequency of 280MHz. Thus, even when the signal whose frequency is 210MHz is fed to the band pass filter 23 via the mixing circuit 24, the signal cannot pass through the band pass filter 23 and prevents an interfering radio wave from being given to another radio receiver, resulting in avoidance of radiation from an antenna 21 via a high frequency amplifier circuit 22.
Patent JP-H03201842-A (JP)
Title: Buffer device
Inventor: OTSUKA EIJI
IPC: H04L7/00
Filed: 1989-12-28
Abstract: PURPOSE:To make circuit scale compact by sharing one memory means for phase difference between transmission and reception data and further deviating access timing even when the competition of access is generated. CONSTITUTION:When an address to be accessed by respective two ports is competed, a memory means 31 gives a priority right to one port and inhibits the access to the other port. Thus, since a detecting means 38 (27) connected to one inhibited port stops referring a transmission clock, an address generating means 23 (24) stops the address output operation during the inhibition. Since the inhibition is released when the access of the port on the priority right side is finished, the operation is restarted and the address, which is competed at the time of the above mentioned competition, is accessed again. Therefore, since timing is deviated afterwards, the competition of the access is not generated between the two ports. Thus, transmission and reception systems can be exchanged through the common memory 31.

Title: Photoelectron multiplier
Inventor: OSUGA SHINJI
IPC: H01J43/00
Filed: 1989-12-29
Abstract: PURPOSE:To reduce the dark noise component based on the luminous phenomenon due to radioactive impurities and cosmic rays and perform the low- background light measurement by turning off a counter counting output pulses from the final dynode of a secondary electron multiplier electrode. CONSTITUTION:When outputs are obtained from both anodes 20A, 20B of a concurrent counting device 24, the gate of a counter 22 is closed, and the counter 22 does not count the output from the final dynode 17 of a secondary electron multiplier electrode 16A. When there are dark noises based on the luminous phenomenon due to radioactive impurities and cosmetic rays, the counting by the counter 22 is canceled. The measured light is weak and enters only into an photoelectric face 14A in the single photon phenomenon, and photons do not feed outputs to anodes 20A, 20B of the first system and the second system concurrently. The effect of dark noises is prevented, the S/N ratio is increased, and the measured light can be counted.
