Title: Junction controller for guiding facilities of traveling vehicle
Inventor: ISHIDA HIDEO
IPC: G05D1/02
Filed: 1987-09-18
Abstract: PURPOSE:To simplify the structure of a communication device while performing the running control of traveling vehicles via the communications carried out among these vehicles themselves, by performing the drive control with use of just a single type of signal at an intersection. CONSTITUTION:The intersection marks M0-M3 are detected by an image sensor 7. Based on the detection information of the sensor 7, a controller 6 decides the start and end points, the number and the priority order of an intersection K. A communication device 8 contains a light emitting diode 9 and a light receiving diode 10 for transmission and reception of optical signals. The communication is carried out between the traveling vehicles by means of said optical signals. In this case, the frequency of an optical signal to be used is available in three types fa-fc so that the communication is carried out by the optical signals of different frequencies at each of adjacent intersections K. Thus it is possible to perform the communication between unmanned vehicles via a simple and inexpensive communication device and also to attain the desired junction control at an intersection.

Title: Charging current control circuit
Inventor: HATANO RIKUO
IPC: H02J7/10
Filed: 1989-09-12
Abstract: PURPOSE:To charge a secondary battery with a voltage having magnitude close to that of the output voltage from a DC power source by connecting a diode between the base and emitter terminals of a current limiting transistor and interrupting current flow through the base terminal of the transistor when the voltage of the secondary battery exceeds the voltage of the DC power source. CONSTITUTION:When the output voltage of a secondary battery 23 approaches the output voltage of a DC power source 27 upon finish of the charging operation of the secondary battery 23, output from a voltage comparator 12 is inverted to turn a transistor Q3 OFF. Since a resistor R2 and a diode D1 maintain the potential at the base terminal of a transistor Q2 at a level approximately same as that at the emitter terminal, the transistor Q2 is turned OFF to interrupt charging current. Consequently, charging voltage for the secondary battery 23 does not drop due to the voltage drop across the diode D1 and the secondary battery 23 can be charged with a voltage having magnitude close to that of the output voltage from the DC power source 27.

Abstract: PROBLEM TO BE SOLVED: To provide a font preparing method capable of reducing the number of input characters, and preparing fonts unified as the whole. SOLUTION: Font data as to three characters, for example are prepared as indicated in column A in the figure to be input. Since the three characters are broken down into six parts as shown in column B when seperated into left-hand radicals and right-hand radicals, the respective parts are stored in a data base. Then, the six parts stored in the data base are combined appropriately or used alone pursant to a prescribed composing rule to prepare six characters as shown in column C of the figure. Since the six characters are prepared based on the three character fonts, the six character fonts are formed with the unified underlying tone only by unifying designs for the three fonts.

Title: On-vehicle cold insulation cabinet
Inventor: NAKAJIMA SAKAE
IPC: F25D16/00
Filed: 1997-09-02
Abstract: PROBLEM TO BE SOLVED: To suitably transport an article without necessity of cold insulation by suitably thawing a cold storage agent immediately after cold insulation. SOLUTION: When a door 2 of the cold insulation cabinet is opened and an operation selecting switch is shifted to 'thaw' in the state that a commercial AC power source is connected, cold storage agent 8 is thawed by a heating operation generated at an evaporating pipe of a cooler, a thawing blower 9 is simultaneously operated to forcibly supply an air flow to the agent 8, thereby accelerating the thawing. Accordingly, even in the case of freezing part of the agent 8 immediately after the cold insulation, the switch is shifted to the 'thaw'. Thus, heating of the agent 8 by the cooler and the forcible air supply to the agent 8 by the blower 9 are simultaneously executed, and hence thawing of the agent 8 can be suitably executed in an extremely short time.

Title: Method and device for processing blood by plasma exchange
Inventor: NAKAYAMA TAKEHISA
IPC: A61M1/00
Filed: 1996-09-09
Abstract: PROBLEM TO BE SOLVED: To suppress the progress of the clogging of a separation membrane and to perfectly execute a required blood processing without interruption in the midst of the processing and affecting limit by controlling the flow rate of a blood pump as the function of difference pressure at the separation membrane in a plasma separator. SOLUTION: The flow rate of a blood pump is controlled by monitoring the values of blood taking pressure P1, vein pressure P2 and plasma separator difference pressure and, at the same time, permitting it not to exceed these limit values. Unless the limit of these kinds of pressure is received, the flow rate of the blood pump is increased by a preset initial speed increasing quantity till an integrated flow rate reaches a prescribed value. The integrated flow rate is set to be almost equal to capacitance obtained by adding a blood taking circuit to the plasma separator. When the integrated flow rate of blood reaches the prescribed value, the flow rate increasing rate of the blood pump is changed- over to the normal speed increasing quantity so that the flow rate reaches a target blood flow rate. After that, the operation of the blood pump is controlled so as to keep the target blood flow rate.

Title: Optical element
Inventor: MIHARA AKIO
IPC: H01L27/14
Filed: 1991-08-23
Abstract: PURPOSE:To suppress the loss of light so as to obtain a high sensitive light receiving element by arranging a resin stream barrier along the lengthwise direction lined with light receiving picture elements of line sensor. CONSTITUTION:A resin flow barrier 3 is placed along the edge lined with the light receiving elements of a line sensor 2 mounted on a substrate 1. The resin 4 for sealing can be prevented from flowing over the light receiving picture elements with an aid of the barrier. In consequence, the light receiving face becomes parallel to the resin face and an incident light enters the light receiving face vertically, the light loss due to the reflection or refraction on the resin face can be suppressed, so that the sensitivity of the sensor 2 is further improved. Moreover, it is preferred that the height of the barrier 3 is approximately equal to that of a thin metallic wire 5, resulting in improving the parallelism between the light receiving face and resin face. On the other hand, it is desirable that the barrier material has a refractive index almost equal to that of the resin in order to prevent the reflection or scattering on the barrier 3.

Filed: 1989-09-13
Abstract: PURPOSE:To improve the efficiency of a compressor by mounting an insulation material on the outer peripheral surface of a rolling piston to form a groove thereon while providing an engagingly portion locking for engaging the groove of said rolling piston on the distal end of a vane. CONSTITUTION:A rolling piston 12 is mounted rotatably on the outer periphery of an eccentric part 7a of a crankshaft 7 to stick an insulation material 12b on the outer peripheral surface thereof. The piston 12 is provided on its outer peripheral surface with a groove 12c against which abuts the distal end of a vane 14 as an engagingly locking part for blocking the piston 12 from rotation. Thus, the relative position between the piston 12 and vane 14 is kept constant, and the outer peripheral surface of the piston 12 located at the suction side is always exposed to cold suction refrigerant gas to provide the low temperature condition. Also, the insulation material 12b stuck on the outer peripheral surface of the piston 12 adds an insulation effect, so that the temperature rise of the refrigerant gas is reduced. Thus, the temperature rise of the suction refrigerant gas is restrained so that the heat loss of suction gas is reduced to improve the efficiency of a compressor.
