Title: Analog-digital converting circuit
Inventor: FUJITA TAKAO
IPC: H03M1/50
Filed: 1984-11-12
Abstract: PURPOSE:To make a response time highly speedy by connecting a modulating signal to a measured analog signal input terminal side of the first switch, and changing over the first switch by the output of the frequency dividing circuit. CONSTITUTION:A frequency dividing circuit 7 divides the output clock phi of a clock pulse generating device 5, generates a modulating signal voltage + or -Ec, and the output of the frequency dividing circuit 7 is inputted through a resistor Rc via a switch SW1 to an integrating device 2. A switch change-over signal INT from the frequency dividing circuit 7 controls to change over the switch SW1. When a measured analog signal Ex is inputted from an input terminal TM1, the integrator 2 executes the integrating action including the measured analog signal Ex besides the modulating signal voltage + or -Ec and a reference voltage +Es. Thus, an analog digital converting circuit does not increase a clock frequency and the response characteristic is made highly speedy. The frequency of the synchronizing clock may be the low one to the extent that the frequency is accommodated several times during the integrating time, and the analog digital converting circuit can easily be made highly speedy.

Title: Signal lamp
Inventor: OGAWA TOKIO
IPC: G09F13/20
Filed: 1998-08-24
Abstract: PROBLEM TO BE SOLVED: To obtain a signal lamp capable of smoothly controlling traffic by providing the signal lamp with a light emission part having two light emitting parts for displaying a dangerous color and a color other than the dangerous color and light emitting elements shared by the two light emitting parts. SOLUTION: The signal lamp is constituted of the light emission part 1 and a group of light emitting elements 51. A 1st light emitting part 10 provides a color displaying a dangerous color on a traffic sign. Thereby, an optical signal indicating the inhibition of passage can be provided for passersby or the like by emitting the 1st light emitting part 10. A 2nd light emitting part 20 provides a color other than the dangerous color. Thereby, an optical signal indicating the permission of passage can be provided for passersby or the like by emitting the 2nd light emitting part 20. Plural light emitting elements 51 are built in the light emission part 1 and shared by the 1st and 2nd light emitting parts 10, 20. Since a partition board for optically separating between both the light emitting parts 10, 20 is not included, the weight of the signal lamp can be reduced.

Title: Reception device
Inventor: NISHIKAWA MOTOHISA
IPC: H04L7/00
Filed: 1994-09-30
Abstract: PURPOSE: To reproduce the received data on an optional time base by transmitting a control signal to the transmission side in response to the detection result of an occupied variable of a storage means and also generating a read clock signal by a read clock generation means. CONSTITUTION: When a buffer part 1 is set in an enable state by a write clock signal WCK received from a transmission device 4 the part 1 stores the supplied data. Then the part 1 supplies a half flag, for example, to a CPU 3 as the information on a memory area to be occupied. The CPU 3 shows the quantity of data supplied from the transmission side as an occupation rate against an entire memory area based on the half flag received from the part 1 and monitors this occupation rate. When the data written in the CPU 3 exceed a prescribed occupation rate, the transmission of the device 4 is discontinued. Then a request signal REQ is sent to the device 4 for request or transmission of the data written in the CPU 3 is kept less than the prescribed occupation rate.  An external synchronizing signal is inputted to a read clock generation part 2, and a read clock RCK synchronizing with the external synchronizing signal is supplied to the part 1. Thus the part 1 reads out its stored data and outputs them.

Abstract: PROBLEM TO BE SOLVED: To prevent the properties of erasing information recorded by heat over time from being deteriorated and increase heat resistance to enhance durability by using two or more different types of resins with varying glass transition temperature consisting of a resin with high transition temperature as a main body and dispersing these resins in the form of a lump. SOLUTION: From the viewpoint of a mechanism to form a milky image and erase an image in the reversible thermal recording material, a preferable lump-like dispersion is generated not only when a curable resin and a noncurable resin are mixed but also when two or more different types of resins with a high glass transition temperature (Tg) and a resin with a low glass transition temperature (Tg) are mixed. In addition, the reversible thermal recording material contains a dispersed lump-like resin C excepting an organic low molecule in the resin A of a reversible thermosensitive layer. The preferable size of the lump is 100Å or more in the form of a microgel from the viewpoint of the durability of the thermosensitive layer. On the other hand, the image contrast tends to deteriorate, if the lump size is 10,000Å or more.

Abstract: PURPOSE:To improve the flow of resin at the time of molding by horizontally positioning the crystal oscillator with a frame, vertically positioning it with a mold guide pin and letting the top end of the guide pin get out of the cylindrical top end of the crystal oscillator or the like. CONSTITUTION:Resin 1 is injected in the state to of horizontally positioning a cylindrical crystal oscillator 3 shown in the cross-section with a frame 5 and vertically positioning it with the mold pin (not shown in the Figure). Upper and lower holes 6 are the tracks of ejecting the guide pin. Since the interval of the frame 5 is made is little wider than the crystal oscillator 3, no stress is exerted to the frame 5.
