Title: Surface light emitting device
Inventor: YOSHIKAWA YUKIO
IPC: F21V8/00
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To increase the amount of light emitted outside of a light guide plate held at a distance from a light source, if the density of recesses provided in the light guide plate is given stepless differences, by preventing the recesses from fluctating in shape with positions, and making the intervals between the adjacent recesses smaller for an increase in the density at which the recesses are arranged. SOLUTION: This surface light emitting device has a light source placed on one or both sides of a light-transmitting light guide plate 1 and provides illumination by introducing the light of the light source into the light guide plate and causing the light to be scattered by diffusers arranged parallel to each other on a light emitting surface. In this case, projecting dies 103 for forming a number of recesses 6 on the back opposite to the light emitting surface in a high density roughly proportional to the distance from the light source are injection molded from a light-transmitting resin material using a molding die 101 obtained from a matrix M machined by a cutting tool 30 having an apex angle θ.

Title: Volume diminishing apparatus for waste synthetic resin
Inventor: NISHIMURA KEIJI
IPC: B29B17/00
Filed: 1990-03-22
Abstract: PURPOSE:To volume-diminish waste synthetic resin having high moisture content completely efficiently by draining water, which is supplied together with waste synthetic resin to a cylinder, from a drainage hole opened into the bottom of the cylinder. CONSTITUTION:The waste synthetic resin supplied to a cylinder 1 is heat-melted within the cylinder 1 and then extruded from the cylinder 1. A drainage hole 5 is opened in the opposite side of the transporting direction of the waste syn thetic resin. For this reason, the waste synthetic resin force-fed by a fin 9 is not pressed toward the drainage hole 5 and thus the drainage hole 5 is prevented from being force-charged by the waste resin or foreign matters. If the waste synthetic resin or foreign matters move to the position where they block the drainage hole 5, they are removed easily from the opening by means of the rotating fin 9. The waste synthetic resin water of which is removed at the drainage hole 5 is efficiently heated and melted, as a result, it is volume- diminished thereby.

Title: Stand-alone start system for basic remote concentrator
IPC: H04J3/12
Filed: 1992-03-31
Abstract: PURPOSE:To start a stand-alone operation of the basic control line concentrator even if the data link communication is impossible by providing a pseudo call circuit to monitor the calls given to a master station and answers received from the master station. CONSTITUTION:A calling display bit is turned on in a test time slot included in a line concentration highway of a remote control line concentrator 1 via an exchange device 5 of a pseudo call circuit 6. The calling is detected via a multiplex transmission line 3 as long as a master station 4 is normally operating and sent back to DT test time slot. The circuit 6 monitors the return of the DT (bothway tones) for a fixed time. The normal operation of the station 4 is decided if the return of the DT is confirmed. Thus the preceding monitoring operation is carried on with no shift to a stand-alone state. If no DT is returned, an abnormal state of the station 4 is decided. Then the shift to the stand-alone state is instructed to the station 4 and the concentrator 1. In a stand-alone state, the circuit 6 calls repetitively and the DT monitoring is carried on. When the return of the DT is confirmed, the normal operation of the station 4 is decided and the stand-alone operation is discontinued. Thus the stand-alone operation can be started even if the data link communication is impossible.

Title: Moving object detector
Inventor: TSUWA AKIMASA
IPC: G01S7/40
Filed: 1978-06-20
Abstract: PURPOSE:To enable fault detection to be readily, rapidly and surely done through remote operation by temporarily superposing an AD voltage to the DC voltage for operating a microwave oscillator thereby producing an artificial Doppler signal. CONSTITUTION:In case when detection of moving objects is made as, e.g., an intruder detector for crime prevention and in order to check the presence or not of its fault, a switch 17 is changed over to the pulsation generating circuit 16 side, by which pulsating voltage is applied to a microwave solid state oscillator 15. Then, the oscillation output of the microwave solid state oscillator 15 is amplitude-modulated by this pulsating voltage and therefore even if no intruder exists in the detecting space, the output signal of a mixer 2 comes to have AC components, thus becoming the same as the Doppler signal by an intruder. Hence, by amplifying this AC signal in a low frequency amplifier circuit 7 and subjecting the similar signal processing to that of ordinary Doppler signal, the detection output may be obtained.

IPC: G01K13/02
Filed: 1980-06-06
Abstract: PURPOSE:To prevent a fluid to be measured from flowing into the sensor-protecting body and enable a sensor to be mounted and dismounted without stopping the operation and without removing the running water flow at the measuring part, by employing a sensor-protecting body having a double structure, and making the outer and inner tubes move relatively to each other. CONSTITUTION:The inner tube 42 is axially movably inserted into the outer tube 40 by means of a screw 44. A water-introducing hole 46 is provided at the end of the outer tube 40. Water-introducing holes 48 are provoded in the side wall of the inner tube 42. Inside the inner tube 42, a temperature-measuring sensor 52 is inserted. When temperature is measured, with the sensor 52 inserted inside the inner tube 42, the inner tube 42 is relatively moved toward the side of the remoter surface 68 from the running water by means of the screw 44 so that the end of the inner tube 42 separates from the water-introducing hole 46 in the outer tube 40. Thereby, the water to be measured passes through the water-introducing hole 44, an air gap 50 and the water-introducing holes 48 and reaches the sensor 52.

IPC: B41J2/36
Filed: 1988-03-31
Abstract: PURPOSE:To perform high grade and high speed recording imparting uniform density from the beginning, by variably controlling not only one current supply time to each heat generating element corresponding to the temp. of a head but also the current supply cycle of each heat generating element corresponding to the current supply time. CONSTITUTION:The heat generating elements of a thermal head 6 are divided, for example, into four blocks and a current is supplied to said blocks successively to drive the same so as to generate heat. A CPU 1 reads the pulse width W of the enable signal corresponding to the temp. of the thermal head 6 measured by a temp. sensor 7 from the table preliminarily stored in a ROM 2 before starts the recording operation of one line to set the same. Next, it is judged whether the pulse width four times of the pulse width W is smaller than a usual one line cycle TA and, when said width is smaller, one line cycle T is set to TA. When the pulse width larger than TA, 4W+alpha is set to the cycle T. Herein, alpha is properly set according to the specification of the thermal printer and set to about 100mus for example.

Title: Fuel injection device for internal combustion engine
Inventor: SUAI YUUKOU
IPC: F02M69/00
Filed: 1980-06-05
Abstract: PURPOSE: To perform a stable feed of fuel to each of the cylinders, by injecting the fuel at every 120° of crank angle and setting the timing of injection start within a range 15° both before and after the top dead center of each cylinder.  
     CONSTITUTION: As considered intake actions of cylinders #5, #4 in a range 15° each before and after the top dead center of the cylinder #5, an intake valve of the cylinder #5, being in a state immediately after opening, causes a rise-up of air intake flow to retard, then the actual intake action can be understood to start at in the vicinity of 15° after the top dead center. On the other hand, though the cylinder #4 closes its valve at the top dead center of the cylinder #5, a lift of the valve is small immediately before its closing further with the charge of intake air almost in a state of completion, then the intake action is almost completed actually before the closing of the valve. On the contrary, a cylinder #1 is in a state of strong intake action because speed of its intake air flow is in a state immediately before reaching a maximum. In this way, if injection of fuel is started at an angle within a range 15° each before and after the top dead center of the cylinder #5, most of the fuel can be fed to the cylinder #1.
