Abstract: PURPOSE:To obtain a pressure-sensitive color forming recording sheet imparting good developed color density and having a high color forming speed by adding a metal salt of a salicylic acid derivative and a specific urea derivative to the same layer. CONSTITUTION:A urea derivative to be used is represented by formula I (wherein R1, R3 and R4 are an alkyl group or an aryl group and R1 and R2 or R3 and R4 show a group necessary for forming a ring) and one with an MW of 300 or more is pref. As a salicylic acid derivative, a 15 or more C compound having a substitutent at its third position and/or fifth position is pref. and, as the substituent, a 1-20C alkyl group or a 7-20C aryl group is pref. As a metal salt, a Zn-salt is especially pref. A known phenol derivative, a metal salt of aromatic carboxylic acid and the like may be together used in a color forming sheet. An electron acceptive compound, the urea derivative and, if necessary, additives are mixed to be dispersed in a binder and the resulting dispersion is applied to a support along with pigment to obtain a color forming sheet. An electron donating leuco dye is added to the color forming sheet.

Abstract: PURPOSE:To evade the interference of a light beam and to curtail the manufacturing manhour and the cost by constituting the title device so that the light beam is transferred by a time division to plural pieces of light receiving means from a light emitting means by using a light beam direction control means for controlling the transfer direction of the light beam. CONSTITUTION:By using a light beam direction control means 16 for controlling the transfer direction of a light beam, the light beam is transferred by a time division from a light emitting means 15 to plural pieces of light receiving means 14, respectively. The light beam direction control element (light beam direction control means) 16 shows high transmittivity extending over a wide area from a visible area to a near infrared area, its optical activity is varied as to only a part which is placed between two pieces of polarizing plates and to which an electric field of PLZT is applied, and it is operated so as to allow the light beam to pass through against the incident light. In such a way, since many light emitting elements are not required, the interference of the light beam can be avoided, and the manufacturing manhour and the cost can be curtailed.

Title: Exhaust gas return and idling speed control for internal combustion engine
Inventor: YAMAGUCHI HIROSHI
IPC: F02D33/00
Filed: 1978-12-08
Abstract: PURPOSE: To operate EGR and ISC efficiently by a single electromagnetic valve and prevent inconvenience to be caused at the time of switching.  
     CONSTITUTION: Negative pressure which has been adjusted by electromagnetic valve 16 is given to either EGR control valve 5 or ISC control valve 8 via switching valve 17. Switching valve 17 is controlled by switching signal S 8 . At the time when the throttle valve is totally closed, negative pressure is given to the ISC side, and to the EGR side otherwise. Atmosphere valve 18 is controlled by control signal S 9 . It maintains the totally closed condition at all times except when the throttle valve is totally closed, but it is totally opened when the throttle valve is totally closed. For this reason, negative pressure chamber 5' of EGR control valve 5 is opened to the atmosphere, and EGR control valve 5 is totally closed. Consequently, at the time of switching from EGR to ISC, EGR control valve 5 is invariably closed totally, and no EGR is given at the time of idling.

CONSTITUTION:Under the state of T1, the voltage of an input terminal 1 is VDD and if a voltage boosting circuit 2 has double boosting characteristics, the voltage thereof becomes 2VDD. The output voltage VDD' of a constant voltage circuit 3 is set so as to be turned into voltage somewhat lower than VDD and the circuit 3 is let a temperature gradient have in such a way that the output voltage thereof rises with temperature rising. An internal circuit 4 is driven by the output voltage of the constant voltage circuit 3 and is designed in such a way that the operating characteristics thereof become most favorable when the output voltage of the constant voltage circuit 3 is VDD' at normal temperatures. Under the state of T2, the output voltage of the voltage boosting circuit 2 becomes VDD. When the lower limit of the stabilizing voltage range of the constant voltage circuit 3 is to be voltage between VDD' and VDD, the output voltage VDD of the voltage boosting circuit 2 is brought into constant voltage by the constant voltage circuit 3 and the internal circuit 4 is driven by VDD' in the same manner as in the state of T1. For that, the operating characteristics of the internal circuit 4 is favorable.

Filed: 1989-06-14
Abstract: PURPOSE:To enable printed descriptions to be read in visible form whenever required excepting a normal state when the descriptions cannot be read by performing a latent image using a coloring agent and developing it in contact with a developer which reacts with the agent whenever necessary. CONSTITUTION:Paper 1 consists of a coloring agent capsule layer 2 of a coloring agent-containing microcapsule formed on the surface. A latent image 2a of specified descriptions is formed by breaking the microcapsule of the coloring agent capsule layer 2 upon application of printing pressure or writing-stroke pressure on the paper 1. The descriptions cannot be read in this condition as the coloring agent has not yet reached. A solution containing a developer such as acidic clay which develops colors in reaction with the coloring agent of the coloring agent capsule layer 2 is allowed to come in contact with the coloring agent whenever required. Consequently, the latent image 2a develops to a visible image 2b and concealed information can be read.
