Title: Method of construction of foundation pile
Inventor: HASHIMOTO AKIFUMI
IPC: E02D5/50
Filed: 1980-01-26
Abstract: PURPOSE: To construct foundation piles having great supporting force by a method wherein steel pipes, lower ends thereof are provided with tapered pipes, are inserted into pits bored by means of auger screws to which expensive cutters are mounted, the insides and the outsides of the lower sections of the tapered pipes are foot- protected and earth is back-filled into the steel pipes.  
     CONSTITUTION: Auger screws 5 are turned, and steel pipes 1 are inserted into the ground boring pits by means of expansive cutters 8. When tapered pipes 2 reach the fixed depth of a supporting layer 11, cement milk is injected from the nose gimlets of the augers while the auger screws 5 are slowly raised, the cement milk is consolidated and foot protections 12 are formed. the auger screws 5 are reversed and pulled up, and earth and sand excavated are back-filled into the steel pipes 1. Thus, the insides and the outsides of the steel pipes 1 are back-filled with earth, foundation piles 13 using the steel pipes 1 as principal bodies are formed, and the piles having extremely great supporting force can be constructed by means of the steel pipes 1 and the foot protections 12.

Title: Ink jet recording
Inventor: MIYAMOTO SHIGEHIKO
IPC: B41J2/21
Filed: 1981-01-22
Abstract: PURPOSE:To enable two types of paper, hard and soft, to be used in an ink jet recorder which is capable of printing multicolor record at a high speed, by causing ink dots to jet out and adhere to, so as to form a reflected image, on the surface of a roll-like transfer medium which attracts, but does not absorb ink dots. CONSTITUTION:Ink particles 4 jetted out in response to signals of a piezo-electric element 12 installed to a recording head 8 form a reflected image in dots on the surface of a transfer roller 1. This image 5 passes through between a pressure roller 2 and the transfer roller 1. Images are transferred one by one on the surface of a medium to be recorded 3. Multi-color recording can be made by changing the color of ink in each of ink heads 8... In this manner, recording can be made on the surface of both stiff recording medium and soft recording medium by the same device and the gap between the recording head 8 and the image forming surface 1 can be precisely maintained.

Title: Document reader
Inventor: MIYAWAKI TADAMITSU
IPC: H04N1/00
Filed: 1998-01-20
Abstract: PROBLEM TO BE SOLVED: To provide a document reader capable of securing the stable quality by quantitatively evaluating the quality of a read document. SOLUTION: A recognition result evaluation part 6 evaluates the quality of document text data generated by an image input part 2 and a character recognition part 4 based on the recognition accuracy of respective characters. Whether the evaluated quality satisfies a prescribed qualified condition or not is judged, and when the condition is not satisfied, a parameter changing part 8 changes an image reading parameter of the image input part 2 to reread the image. Basically the feedback loop is repeated until prescribed quality can be obtained. For example, the reading resolution of the image input part 2 is used as the parameter, which is stepwisely increased according to the number of loops.

IPC: G01R31/26
Filed: 1982-01-22
Abstract: PURPOSE:To measure ballast resistance of a transistor easily and accurately, by utilizing the fact that proportional relation determined by ballast resistance holds approximately between a voltage between a collector and an emitter, and an emitter current. CONSTITUTION:When a switch SW is not closed, small current Ia flows by a constant-current power supply 2 in the base of a transistor 1 to be measured. The value indicated by a voltmeter 4 at this time is assumed as Va. When the switch SW is closed, current Ib supplied by a constant-current power supply 3 flows together with Ia. The value indicated by the voltmeter is assumed as Va 4. Ia is a value sufficient to approximate at normal temperature, and if R2 is large enough, almost current supplied by constant-current power sources 2, 3 flows in R1, and ballast resistance of the transistor 1 to be measured is determined by the following equation R1=(Vb-Va)/Ia.

Title: Traffic control system for communication processor
Inventor: KAMIJO AKINORI
IPC: H04M3/22
Filed: 1987-01-20
Abstract: PURPOSE:To smoothly process a signal or data flow without executing a high load control procedure to a tentative load concentration by estimating the rate of use of a transmission buffer from signal line transmission speed and a signal transmission request quantity and applying queue connection to a signal transmission request when a prescribed limit is exceeded. CONSTITUTION:An estimating means 13 estimates the rate of use of a transmission buffer 12 from the capacity of the transmission buffer 12, the transmission speed of a signal line 10 and the signal transmission request quantity. A signal transmission request generated newly is connected to a queue 14 by the estimating means 13 when the estimated rate of use exceeds a prescribed limit and a signal is transmitted from the queue 14 to the transmission buffer 12 to limit the load quantity of the transmission buffer 12. Thus, even if tentative concentration of traffic estimated to exceed the transmission buffer quantity of a communication processor takes place, and the transmission load quantity to the transmission buffer is relieved without starting a high load control procedure.

Filed: 1989-01-17
Abstract: PURPOSE:To improve reliability and reduce a cost for production by sandwiching each terminal of a terminal unit between contacts of a movable contact unit and arranging the terminal unit as the terminal is engaged with a terminal inserting slot of a terminal case. CONSTITUTION:When a push button 31 is depressed, an operating shaft 35 is pushed down until a flange portion 352 of the push button 31 touches an upper edge of a cylinder portion 334 of a case 33. A movable contact unit 40 is also pushed down in an unit 60. This push button is configured such that a contact portion of each of terminals 62a to 62c is sandwiched between two contact portions 421 of a contact 42. Thus, contact is firmly made. When contact configuration is changed, it is only needed to change combination of the terminals 62a to 62c which are to be inserted into a terminal inserting slot 611 of a terminal case 61. Thus, the terminal case 61 is shared among push buttons with different Contact configuration with each other. Therefore, a cost for the push button is reduced.
