Title: Automatic answering telephone system
Inventor: MORITA YOSHIKAZU
IPC: H04M1/65
Filed: 1991-12-24
Abstract: PURPOSE:To provide an answering telephone system designed for the specified person among callers who are somewhat repulsed by recording a message, capable of keeping the information showing who the caller is without recording a message with simple operation. CONSTITUTION:A display information input section 16 inputs the name of the opposite destination corresponding to the dial number of a dial number storage section 9 to be stored in a display information storage section 17. When a caller ends one part of his dial number by a DTMF signal in answering during his absence, a DTMF signal detection section 5 detects the signal and a control section 14 collates the dial number registered by a dial register input section 8 and stored in a dial number storage section 9 with the received DTMF signal, reproducing the dial number. When the display control section 15 retrieves the opposite destination in answering during the absence, the name of the opposite destination corresponding to the reproduced dial number is drawn from the display information storage section 17 and the list of the name of the opposite destination is displayed on a display section 18.

Filed: 1989-12-29
Abstract: PURPOSE:To obtain a transfer image with stable picture quality by controlling the surface potential of transfer paper corresponding to a transfer electric field, and preventing density changed due to working environment. CONSTITUTION:The surface of a photosensitive material 1 is electrified with an electrifier 2 as being rotated in a direction of A, and the photosensitive material 1 is irradiated with beam light 18 from an exposure unit 3. Then, image information is formed on the photosensitive body 1 as an electrostatic latent image based on difference between the brightness and darkness of the beam light 18, and the static elimination of a selectively exposed position is performed. At such a case, an electric field is formed between a developing roller 6 and the photosensitive body 1, and a developer 5 is attached on the part of the photosensitive body 1 where no electric charge exists, then, the electrostatic latent image is realized as an actual image. At this time, when environmental temperature is changed, surface resistance is changed due to water content of transfer paper 12, therefore, a constant transfer electric field can be supplied by controlling a resistor 16 with a control circuit 17. Thereby, it is possible to prevent the density fluctuating due to the change of the working environment, and to always obtain the transfer image with superior picture quality.

Title: Removing agent for decorative wallpaper having vinyl decorative layer
Inventor: MIYAKI KANJI
IPC: C09J7/02
Filed: 1997-11-27
Abstract: PROBLEM TO BE SOLVED: To obtain a removing agent which easily remove a cured vinyl decorative layer by using N-methyl-2-pyrrolidone as the principal component. SOLUTION: This agent contains N-methyl-2-pyrrolidone as the principal component and optionally contains a dissolution/swelling agent (e.g. dichloromethane) for a vinyl decorative layer, It requires that the penetration of N-methyl-2-pyrrolidone into a vinyl decorative layer should be performed in a coating weight of about 200 g/m<2> for about 2 hr. The amount of the dichloromethane added is at least 10 wt.%, desirably, 20-30 wt.%, based on the removing agent. In order to prevent dichloromethane, which is a readily volatile substance, from being evaporated, it is desirable to disperse in the removing agent a polar wax (e.g. oxygenous wax prepared by mixing a paraffin wax with a wax prepared by reacting an α-olefin with maleic anhydride to form dicarboxylic acid groups at part of the straight chain). Further, in order to improve the applicability of the removing agent, it is desirable to add a thickener (e.g. methyl cellulose) to it.

Abstract: PURPOSE:To dispense with the monitoring of the use number of times of a multipass ink ribbon, in a recording apparatus using the multipass ink ribbon, by providing a control means performing ribbon reverse feed operation returning the ink ribbon to the first printing start position after the completion of printing. CONSTITUTION:In the recording apparatus using, for example, a multipass ink ribbon susceptible to printing twice of a thermal transfer type facsimile apparatus, the printing number of times of the ribbon surface of an ink ribbon R is judged on the basis of the running position data of the ink ribbon R stored in the counter of an RAM at the time of recording operation.

When the printing of the ink ribbon is judged to be the second time, it is judged whether the ink ribbon is returned to the first printing start position and, when the ink ribbon is not returned, a stepping motor 20 is returned to the first printing start position of the RAM. After this return is confirmed, the second printing operation is executed under the first printing condition.

Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To carry out moderate and favourable air-fuel ratio control until an O2 sensor reaches its end of life by compensating responsiveness delay caused by deterioration of the O2 sensor, etc. SOLUTION: An upper limit value RLUP and a lower limit value RLDWN of a time ratio RL are set (S18) by computing (S17) the time ratio RL of rich continuing time TR and lean continuing time TL detected in accordance with an O2 sensor output value VO2 and by table reference in accordance with intake air quantity Q. Additionally, at the time when the time ratio RL is equal to or higher than the upper limit value RLUP (RLUP<=RL), an air-fuel ratio feedback correction coefficient is renewed (S20) by a value that a lean correction proportional component PR to skip in the lean direction is extended by a set value KHOS1, and at the time when the time ratio RL is equal to or lower than the lower limit value RLDWN (RLDWN>=RL), the lean correction proportional component PR is renewed (S22) by a value reduced by an amount of a set value KHOS2.  Consequently, responsiveness delay due to deterioration of an O2 sensor, etc., is compensated by the lean correction proportional component PR, and the air-fuel ratio is controlled so that the time ratio RL is kept within an allowable value.
