Patent JP-H03197821-A (JP)
Title: Ultrasonic flowmeter
Inventor: UCHIYAMA MASARU
IPC: G01F1/66
Filed: 1989-12-26
Abstract: PURPOSE:To obtain the accurate predicted flow rate of even an unsteady flow by substituting the flow velocity signal which is outputted with a flow velocity detecting means for the mean flow velocity part of a conduit model which is calculated by a predictive arithmetic means, and calculating and outputting the unsteady flow rate. CONSTITUTION:Ultrasonic wave pulses which are sent out of an ultrasonic wave pulse transmitter 2 are made incident at an angle alpha to the flow direction through a tube wall 1', received by an ultrasonic wave receiver 2' through a slanting wedge 3' at the facing position, and sent from the transmitter 2 again through an amplification device 4 and a pulse transmitter 5. This operation is repeated to equalize the cycles of ultrasonic wave pulses to a propagation time t1, and its frequency is represented as f1=1/t1. Then when a switch 7 is changed over by a timing circuit 6, the path of the ultrasonic wave pulses is inverted and a pulse frequency f2 is represented as f2=1/t2, where t2 is the current propagation time; and the mean flow velocity V is found from the difference DELTAf in pulse frequency by using V=DELTAf.D/sin2alpha (D: conduit internal diameter) and outputted from a converter 8. Then a predictive arithmetic means 10 inputs the mean flow velocity signal and the estimated value of an instantaneous flow rate is displayed 16 as an actual flow rate signal.

Filed: 1998-11-30
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for preparing a large quantity of print content to be updated by returning a print content being updated at a specified interval back to the first print content every time when an update cycle time or interval longer than an update time or interval elapses. SOLUTION: A print content being updated at a specified time elapse monitoring section (updating means) 42 in a count update timing detecting section every time when a specified time or interval elapses is returned back to a first print content at an update cycle elapse monitoring section (update cycle means) 43 every time when an update cycle time or interval longer than the update time or interval of the updating means elapses. Since sequentially updated print content is repeated at a specified period, the need for preparing extremely large quantity of print content can be eliminated and the memory capacity can be reduced at the control section including the monitoring sections.

Title: Broad area laser
Inventor: NONAKA HIDEYUKI
IPC: B23K26/00
Filed: 1989-12-28
Abstract: PURPOSE:To offer a broad area laser which can be easily manufactured and controlled in lateral mode by a method wherein an electrode which is low at its center and high at its ends in contact resistance in a broadwise direction is provided on a current path. CONSTITUTION:A region W formed of the stripe-like opening of an insulating film 6 is made to serve as a current path. Moreover, in this device, in the broadwise direction of the strip-like opening or in the region W, a region of a cap layer 5 in contact with a P-side first electrode 7 and another region of the cap 5 in contact with a P-side second electrode 8 are different from each other in contact resistance. The P-side second electrode 8 is positioned on the P-side first electrode 7 but the P-side first electrode 7 is thick enough, so that the P-side second electrode 8 has no effect on the contact resistance between the cap layer 5 and the P-side first electrode 7. In result, the gain of this device is distributed in the region W in such a manner that it is high at the center and low at the ends. Consequently, oscillations of high order modes are restrained, and a laser of this design oscillates only in a base mode.

Title: Memory device
Inventor: KAWAHARA HIROKAZU
IPC: G06F12/00
Filed: 1995-12-27
Abstract: PURPOSE: To conduct the fast-in fast-out action of large capacity information signals at a high speed by providing two static memories. CONSTITUTION: First and second static memories 1, 2 conducts the fast-in fast- out action to information signals fed while a dynamic memory 3 receives the information signal from the first static memory 1 and delivers the information signal to the second static memory 2. A memory detection means 4 detects the blank capacity of the second static memory 2 and the presence of information signal written in the dynamic memory 3 and not read out yet. When the information signal is read out from the first static memory 1, a control stage 5 delivers the information signal being read out while switching between the second static memory 2 and the dynamic memory 3 depending on the detection results from the memory detection means 4.  Since the information signal can be transferred between the first and second static memories 1, 2 without passing through the dynamic memory 3 when the second static memory 2 has a blank capacity, high rate operation is realized.

IPC: G03D3/00
Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To rapidly develop a film with a treating liquid at proper temp. SOLUTION: A stabilizer is not derailed from a treating tank but kept in the tank to heat the treating tank with the stabilizer (128). When the absence of the treating liquid in the treating tank is detected (102), a heated stabilizer liquid is supplied to the treating tank to heat the tank (104). Namely, before a film is introduced into the treating tank, a finish treating liquid heated is supplied to fill the treating tank by a treating liquid supply means. The film is inserted through the film inserting port into the treating tank and developed by successively supplying and changing pleural kinds of treating liquids in a specified order from a stack tank to the treating tank. Therefore, when the film is inserted, the treating tank is maintained hot by the liquid temp. of the heated finish treating liquid, the film can be rapidly developed in a proper state.
