Title: Metal surface treating agent
Inventor: ENAMI KATSUYUKI
IPC: C23G1/02
Filed: 1990-09-07
Abstract: PURPOSE:To provide a metal surface treating agent free from hydrofluoric acid and can be easily handled and supervised without causing problem concerning safety and sanitariness for working environment by mixing nitric acid, iron (III) nitrate, potassium nitrate, iron (III) sulfate, sulfamic acid and ammonium chloride each by a specified proportion. CONSTITUTION:The metal surface treating agent having good performance can be obtained by compounding the components with compounding ratio as shown in table 1. This metal surface treating agent contains no hydrofluoric acid, so that this agent can be used in a place without an equipment for removing hydrofluoric acid, and the treatment of metal can be performed in a preferably working environment from the view point of safety and sanitariness for working. This is because hydrofluoric acid is toxic and special equipment is required to remove hydrofluoric acid when waste water containing hydrofluoric acid is discharged. Since the treating agent contains nitric acid by <10wt.%, it is regarded as no toxic nor drastic in compliance with Regulation Low of toxicant and drastic chemicals. Therefore, no superviser for handling toxic and drastic chemicals is required, which simplifies the management and handling of the agent. Moreover, this agent effectively removes corrosive products and oxide scales from metal surface and etches the metal properly, not excessively, so that the metal has a smooth and beautiful silver-while finish surface.

Title: Tv relay system in catv network
Inventor: ASARI ATSUSHI
IPC: H04N7/173
Filed: 1998-08-25
Abstract: PROBLEM TO BE SOLVED: To make the occupied frequency band narrower by avoiding an effect such as a noise produced on a transmission line of an incoming TV relay channel. SOLUTION: A TV relay terminal 15 digitizes an analog video signal and an audio band signal outputted from a TV camera 1, uses a carrier of a predetermined frequency band of an incoming channel and transmits the signals to a TV repeater 31a or 31b as a TV relay signal and the TV repeater 31a or 31b detects a bit error caused in the received TV relay signal. In the case that a detected frequency of a bit error is much more than a predetermined value, an instruction signal to change a frequency band of a carrier to other frequency band with less occurrence of the bit error is outputted to the TV relay terminal 15, which converts a transmission frequency band of the TV relay signal to the other transmission frequency band according to the instruction signal.

Abstract: PURPOSE:To prevent wear of a magnetic disk by specifying the Knoop hardness of nonmagnetic particles mixed in a recording layer of a magnetic recording medium selected larger than that of a material used for a slider of the magnetic head. CONSTITUTION:A magnetic recording layer 20 is formed on a base 4 of a disk, and the recording layer 20 is formed by mixing nonmagnetic particles 1 and magnetic particles 2 into a resin 3. As the magnetic particles 2, for example, Fe2O3 is used, the nonmagnetic particles 1 act like a reinforcement member, and an artificial diamond is preferred. The resin 3 is, e.g., and epoxy resin and the nonmagnetic particles 1 and the magnetic particles 2 act like a binder to be coupled with the base 4. The Knoop hardness of a diamond is more than 3000, e.g., nearly 8000, and harder by a multiple of nearly 3.6 times than the hardness of nearly 2200 of a mixture comprising Al2O3 and titanium carbide used for the magnetic head. The hardness of the nonmagnetic particles 1 is increased relatively more than the hardness of a slider member of the magnetic head in this way to prevent wear of the magnetic disk.

IPC: G06T7/00
Filed: 1987-09-24
Abstract: PURPOSE:To reduce false recognitions by changing automatically to a suitable reject value by whether a recognition result is correct or not. CONSTITUTION:The matching processing of an inputted unknown input pattern and an N number of standard patterns 1 is executed by a processing part 3 and it is recognized that a specific standard pattern 1 which is smallest out of those that the value of an obtained matching distance does not exceed the respective reject values 2 of the standard patterns 1 coincides with the unknown input pattern. An update value about the reject value 2 is calculated based on the result information of a decision result input part 4 to input the decision result information of whether the information of this standard pattern is correct or not.

Title: Method and device for controlling delivery of baggage
Inventor: INAO MASAYUKI
IPC: B65G43/08
Filed: 1988-09-28
Abstract: PURPOSE:To reduce the load of a host computer by performing no communication related to the baggage delivery schedule between a base computer and the host computer as long as the delivery schedule is kept by the base computer. CONSTITUTION:A base computer 7 performs an order receiving process by a new delivery request and sends the contents of the receiving process and the identification code of an IC card attached to a baggage to a host computer 1. Receiving a new register request, the computer 1 produces the delivery data and sends this data to the computer 7 via a transfer data control part 2. The computer 7 receives the delivery data and records this data on the IC card via a card reader/writer 9. Then the computer 7 decides the next delivery schedule based on the delivery schedule held by the IC card without having any communication with the computer 1 as long as the delivery schedule is kept. While the contents of the delivery schedule are informed to the computer 1 in case the delivery schedule is not kept.

Title: Electronic control system for single lens reflex camera
Inventor: AKIMOTO RYOICHI
IPC: G03B7/08
Filed: 1999-08-27
Abstract: PROBLEM TO BE SOLVED: To use AE and AF functions at mirror-up photographing similar to those at normal photographing. SOLUTION: The electronic control system is provided with a mirror position detecting switch 40 at a mirror-up start position, and in a state where a starter switch is turned on, locking and storing operations of photometry values and range finder values are executed when a release switch is turned on at normal photographing, while at mirror-up photographing, the locking and storing operations are executed when the off signal of the mirror position detecting switch 40 is detected by a CPU. Thus, by executing a mirror-up operation by operating a mirror-up knob 35 and then turning the release switch on, the mirror-up photographing with the AE and AF functions enabled is accomplished.  Even in the case of changing the composition and illumination in the middle of mirror-up photographing, the photometry values and the range finder values are renewed by executing a mirror-down operation by operating the mirror-up knob 35, and by executing the mirror-up operating again thereafter, the photographing effect corresponding to the new composition and illumination is obtained.

Title: Picture transmission equipment
Inventor: ICHISE ATSUSHI
IPC: H04N1/00
Filed: 1984-11-15
Abstract: PURPOSE:To obtain inexpensive picture angle scanning suitable for unidirectional transmission by providing an image scanner, a data converting means for converting the format of picture information possible for serial print, a unidirectional line and a serial printer at the reception end. CONSTITUTION:A CADA transmitter 2 and a CADA receiver 3 are used. A printer 27 is a serial printer, which prints 24 lines by one serial print. The image scanner IF 5 at the transmission side has a data buffer for 24 lines' share and the transmission side transmits intermittently data in a preset timing in matching with the operating speed of the reception side printer. The data transfer from the transmission side is executed in a short time and while the printer 7 prints once, the image scanner 4 of the transmission side fetches the next new data, and until one print of the printer 7 is finished and the next data transfer is finished, the scanner 4 is in standby state. Since the data is converted into a format possible for being printed by the printer of the reception side and then transmitted, it is not required to provide transmission/reception function to one unit and unidirectional communication without hand-shake is attained.
