Title: Production of acetoacetylated oligomer
Inventor: SHIMOKAWA WATARU
IPC: C07C67/46
Filed: 1985-07-11
Abstract: PURPOSE:To obtain the titled compound, useful as a quick-curing adhesive, etc., and curable without causing reduction in volume, by reacting a specific oligomer with diketene. CONSTITUTION:An oligomer having two or more hydroxyl groups in one molecule is reacted with a diketene expressed by formula I in the presence of a catalyst, e.g. triethylamine (TEA), to afford the aimed acetoacetylated oligomer expressed by formula II. Although an acetoacetylated compound, e.g. acetoacetylated polyvinyl alcohol, is useful as a quick-curing adhesive, etc., by using together with a crosslinking agent, there is a problem of reduction in use by dissolving in a solvent and reduction in volume, since the compound is an acetoacetylated polymer in the solid state. Since the above-mentioned acetoacetylated oligomer is liquid or viscous material at ordinary temperature, it can be cured even by reaction with a crosslinking agent without causing reduction in volume.

Title: Address selection circuit
Inventor: YAMAMOTO TAKAYUKI
IPC: G11C11/406
Filed: 1989-06-15
Abstract: PURPOSE:To prevent malfunction at a row redundancy circuit side occurring by selecting either an external or internal address, inputting a selected address to a row redundancy circuit when a row address strobe signal is activated, and setting both the external and internal addresses at nonselection when it is inactivated. CONSTITUTION:A refresh cycle detection circuit is operated so as to output a first or second signal at the same speed as that of a row address buffer. And switching circuits 35 and 36 always select either the external or internal address with the first and second signals when the row address strobe signal, the inverse of RAS, is activated, and input it to the row redundancy circuit 40. Also, they are operated so as to set the nonselection of both the external and internal addresses when the row address strobe signal, the inverse of RAS, is inactivated. Therefore, it is possible to prevent the malfunction occurring without setting an address switching timing to reduce the speed of the external address even when the difference of speed between the first and second signals for address switching and external address occurs.

IPC: B23K26/361
Filed: 1988-06-21
Abstract: PURPOSE:To improve the speed and quality of trimming by disposing a pulse control means and slit control means to a laser light generator and irradiating the trimming position with laser pulses by using a slit. CONSTITUTION:The laser pulse control means 25 is provided to the laser light generating means 30 and a light attenuating means 28 consisting of an attenuator or polarizing plate is disposed thereto. The slit control means 24 which controls the laser light to an arbitrary rectangular shape and an image means 23 for laser light are successively disposed to the attenuating means 28. The slit is adjusted by the slit control means 24 to form the image in the trimming position to a rectangular shape and thereafter, a positioned object 1 to be trimmed is irradiated with the attenuated laser pulses. Since the processing is executed repeatedly by the extremely weak laser power, the splashing of the splashes of the work to the periphery and the generation of peripheral heat influence are prevented. The speed and quality of the trimming are improved in this way.

Filed: 1990-06-12
Abstract: PURPOSE:To vary the intensity of the exposure of a main object and background exposure optionally by setting an exposure correction quantity and a light emission correction quantity at the time of automatic bracketing photographing individually (independently). CONSTITUTION:An automatic bracketing photographing means 103 takes a specific number of photographs, i.e. automatic bracketing photographing while correcting the exposure successively by the exposure correction quantity which is set by an exposure correction quantity setting means 101. Further, a light emission control means 104 makes an electronic flash light device to emit light while correcting the quantity of light emission in order by a light emission correction quantity set by a light emission correction quantity setting means 102 in synchronism with each automatic bracketing photographing operation. The exposure correction quantity and light emission correction quantity are set independently by different operation. Consequently, the intensity of the exposure of the main object and the background exposure can be varied optionally at the time of the automatic bracket photography.

Filed: 1980-10-31
Abstract: PURPOSE: To detect the occurrence of a fault almost immediately and automatically, by transmitting an originating signal for test when an originating signal is not obtained in the output side of an originating control channel receiver over a constant time and receiving this originating signal for test by the originating control channel receiver.  
     CONSTITUTION: An originating control channel receiver 21 of a radio base station receives the originating signal transmitted from a mobile station and transmits this signal to an exchange through a wire line 3 and sends a pulse signal indicating the receiving of the originating signal to a fault detecting device 22. When receiving a signal A from the receiver 21, the device 22 becomes conductive to set the output potential of a timer circuit to 0. This potential rises by a constant current source in respect to time. If the next originating signal does not come over a constant time, the output of a comparator is sent to a testing transmitter 23, and an originating signal for test is transmitted from the transmitter 23 to the receiver 21, and this signal is received by the receiver 21.
