Patent JP-H0440030-A (JP)
Title: Signal transmitter-receiver
Inventor: KURANAGA HIROSHI
IPC: H04L7/00
Filed: 1990-06-05
Abstract: PURPOSE:To reduce phase difference between a transmitted data signal and a received data signal by controlling the timing of supplying a periodical timing signal to a transmitted data generating means based on a delay time to be generated by a transmitting means and a receiving means. CONSTITUTION:When any specified mode is designated from the outside, the transmitted data signal outputted from a transmitting means 1b is supplied to a receiving means 1a. A phase difference detecting means 9 detects the phase difference between the transmitted data signal outputted from the transmitting means 1b and the received data signal outputted from the receiving means 1a. In response to a detected phase difference signal, a timing control means 10 controls the timing of supplying the periodical timing signal, which is generated from a timing signal generating means 4, to a transmitted data generating means 6. Thus, since the transmitted data generating means 6 generates the transmitted data signal while responding to the periodical timing signal which timing is controlled, it is possible to reduce the phase difference between the generated transmitted data signal and the received data signal.

IPC: H01L21/205
Filed: 1994-06-29
Abstract: PURPOSE:To form an SiOx film which has both the merit of the step coverage of the SiOx film formed by using TEOS and the merit of the film quality of the SiOx film formed by using SiH4. CONSTITUTION:The application of a high-frequency wave to the high-frequency antenna 2 of a helicon wave plasma device can be changed over by a change- over switch 14 to either intermittence or continuation, and the application and interruption of a current to a peripheral side solenoid coil 3b which contributes to the transportation of the helicon wave plasma PH can be changed over by an ON/OFF switch 17. Thereby, plasma density in a belljar and in the vicinity of a wafer (W) can be freely changed. When TEOS is dissociated in low-density plasma, the SiOx film which excels in step coverage can be formed by utilizing excellent flowability of the precursor of film formation, and when SiH4 is dissociated in high-density plasma, an SiOx film which has small residual components and is fine and excels in water resistance can be formed.

Title: Dryer for photographic material
Inventor: HANAWA ITARU
IPC: G03C1/74
Filed: 1990-06-08
Abstract: PURPOSE:To eliminate the unequal drying of a photographic material and to obviate the generation of flawing in edge parts and on surfaces by meandering by forming grooves of prescribed sizes on transporting rolls and shifting the grooves of the adjacent rolls from each other. CONSTITUTION:The rolls B of the dryer for photographic materials provided with the plural transporting rolls B are formed with the grooves 1 of 0.3<=b/a<=5, a=0.1 to 3mm (where (a) is an inter-groove spacing and (b) is a groove width). The grooves 1 are so disposed that the grooves of the adjacent rolls in the traveling direction of the photosensitive material shift from each other. The peripheral surface area of the rolls B increases and the possibility of intruding air into the spacing between a flexible web and the rolls B increase if the above-mentioned quotient is below 0.3. The peripheral surface area of the rolls B decreases and the friction force acting between the web and the rolls B decreases if, conversely the quotient exceeds 5. The trouble that slip motion increases drastically is conversely resulted in such a case.

Title: Beverage agitation and mixing device
Inventor: KATO ISAO
IPC: G07F13/06
Filed: 1996-06-11
Abstract: PROBLEM TO BE SOLVED: To prevent liquid from flowing out from a cup type vessel during an agitation process and cause the liquid to quickly flow out from the vessel after the agitation process by drilling a hole through a disc type agitation vane laid near the bottom of the cup type vessel for concealing an opening. SOLUTION: In addition to a beverage flow passage formed out of a gap between an agitation vane 2 and the bottom 1b of a cup type vessel, another beverage flow passage is formed out of a plurality of through-holes 20 on the agitation vane 2. Thus, a beverage quickly flows out from the cup type vessel after an agitation process. During the agitation process, the beverage is prevented from flowing out from the cup type vessel 1, due to a centrifugal force. Also, as the through-holes 2a are formed to be radially inclined internally from the upper surface of the vane 2 to the lower side thereof, a part of the weight of the beverage tending to enter the through-holes 2a is held on the lower surrounding wall thereof.  As a result, even when the speed of the vane 2 is relatively low and a centrifugal force is relatively small, or even when a centrifugal force is relatively small, due to the through-holes 2a formed at the radial internal position of the vane 2, the ingress of the beverage into the through-holes 2a is properly prevented.

Title: Alarm processing circuit
Inventor: SAITO KAZUAKI
IPC: H04B17/00
Filed: 1989-06-12
Abstract: PURPOSE:To prevent A circuit scale from being so much enlarged even when the number of alarm signals is increased by executing alarm processing to an M-sequence of the alarm signals with time division. CONSTITUTION:A selector 3 selects the M-sequence of the alarm signals to be inputted with the time division by using a timing signal from a timing generating means 2 and successively outputs the signals to a T-time holding/protecting means 4. The T-time holding/protecting means 4 updates the continuing time of the alarm signal. When it is detected that the updated continuing time is T-time, the alarm output of an H level is sent (1-second protection) and updates the state of the stored alarm output. When it is detected that the timing signal continued for more than the T-time is interrupted, the state of the alarm output is set to an L level (1-second holding) when the T-time lapses after the detection. Thus, even when the number of the alarm signals is increased, the circuit scale is not enlarged so much.

Title: Semiconductor photodetector
Inventor: NAKAJIMA NORIICHI
IPC: H01L31/10
Filed: 1984-07-20
Abstract: PURPOSE:To improve the falling characteristic by forming a P<+> type layer for holes to become majority carrier to forcibly collect the holes, thereby controlling it. CONSTITUTION:A photocarrier generated in an InGaAs layer 13 is separated by an internal electric field. Electrons are affected by an electric field between a source 18 and a drain 19 to enter the drain 19, and are led as a signal. The holes are input to a P<+> type region 12 and erased due to the application to the region 12. The time to the erasure relates to the fall of the response, and is determined by CR time constant. Accordingly, it is important that C is reduced by decreasing the area of the P-N junction and P<+> is buried in the layer to improve the responding characteristic. Further, wired as shown, and the influence of hole current component operating to delay the responding characteristic of the output signal is further reduced by operating in a photodiode manner.
