Title: Liquid crystal-polymer composite film, its production and liquid crystal optical element
Inventor: HATTORI SHUJI
IPC: G02F1/1333
Filed: 1995-01-26
Abstract: PURPOSE: To form a good liquid crystal-polymer composite film without using a phase separation method and to obtain a liquid crystal optical element in which the function of dichroic dyes can be enough obtd. by dispersing fine particles which do not dissolve with a liquid crystal in a liquid crystal. CONSTITUTION: When a liquid crystal-polymer composite film is formed by a coating method, fine particles having low solubility with a liquid crystal is mixed in a liquid crystal compsn. to be used for coating. Thus, a liquid crystal-polymer composite film having a liquid crystal layer and a matrix layer of fine particles each forming mesh structure can be formed. By this method, irradiation of UV rays is not required for phase separation so that even when dichroic dyes are added to the liquid crystal, the dichroic dyes do not deteriorate. Further, the matrix polymer is not precipitated from a completely dissolved state like a conventional casting method, the matrix polymer is hardly dyed with the dichroic dyes. Therefore, a liquid crystal optical element excellent in contrast can be easily obtd.

Title: Reception level comparator device
Inventor: FURUYA YUKITSUNA
IPC: H04W64/00
Filed: 1978-03-13
Abstract: PURPOSE:To select the antenna featuring the maximum level of the field intensity and received from the slave station by putting the reception level information of the antenna onto a piece of the signal line with no multiplication. CONSTITUTION:The electric wave received through antenna 6 is amplified at amplifier 701 and then filtered through low pass filter 703 after squared via squaring circuit 702 to be supplied to diode 72 (a combined circuit) via current detector 71 (a decision circuit). The wave received at antenna 6' is supplied to diode 72' via the similar processes as stated above. In case the signal received through antenna 6 is stronger than that received through antenna 6', the input voltage of diode 72 becomes higher than the input voltage of diode 72'. And the potential signal line 5 features the value which is lowered by the amount of the combination voltage of diode 72. In this case, the potential difference between the input and the output of diode 72' becomes smaller than the combined voltage, and thus no current flows to diode 72'.

Abstract: PURPOSE:To prevent the generation of a malfunction by providing a temp. sensor which detects the temp. in a vehicle near the part where a gas sensor is mounted and controlling the input of a motor according to a difference in the signals between the gas sensor and the temp. sensor. CONSTITUTION:The in-vehicle air sucked from a suction port 18 is subjected to removal of dust by a wire net 25 of an electric discharge device 19 when a motor 13 is driven. The fine dust is adsorbed by an electrostatic filter 28. The temp. of the gas sensor 2 rises as the gas sensor 2 adsorbs the gaseous components entering from a ventilation port 5. The motor 13 is controlled by a control circuit 26 according to this signal. The signal from the gas sensor 2 and the signal from the temp. sensor 8 are compared and the contamination of the air in the vehicle room is detected by making investigation that the temp. rise of the gas sensor 2 is not the temp. rise in the vehicle. Since the generation of the malfunction is obviated in this way, the state in the vehicle is maintained always clean.

Title: Cylinder fuel injection device
Inventor: OKAMOTO YOSHIO
IPC: F02M61/18
Filed: 1999-02-08
Abstract: PROBLEM TO BE SOLVED: To obtain a spray configuration that expands a stabilized combustion zone in stratified charge combustion by providing at least a specific number of protrusions that extend toward a central axis at a fuel injection orifice portion. SOLUTION: At least one protrusion 25 that extends toward a central axis is provided at a fuel injection orifice 8 portion. According to this construction, fuel introduced from an upper part of a valve body 6 moves past an axial passageway of a fuel swirl member and a radial passageway that connects to the axial passageway to reach the fuel injection orifice 8. The radial passageway is provided eccentrically with respect to the center of axis, giving fuel a swirl force. A liquid film on an outer peripheral portion at an outlet portion of the fuel injection orifice quickly breaks causing droplets to lose momentum. The protrusion 25 cuts the flow, when air flows in a direction of a void portion from a portion of a cut liquid film. The inflow of air makes the pressure inside a spray equivalent to that surrounding it, thus generating a spray not susceptible to pressure influence.
