Title: Device for detecting character direction in document
Inventor: NAKAMURA YUTAKA
IPC: G06K9/20
Filed: 1990-08-02
Abstract: PURPOSE:To make it possible to accurately detect the character direction of a document even in the case of using an original mixing halftone or graphic or an original of complex column composition by finding out a unit area (circumscribed rectangle), measuring the length (run length) of a space area (color run) in the unit area and deciding the character direction by the distribution of appearance frequency. CONSTITUTION:A picture element area forming means 1 detects a picture element group consisting of mutually relating picture elements in an input image, e.g. a picture element group constituting one character and a picture element constituting one table or a graphic, as a unit area. A run length frequency distribution feature extracting means 3 finds out the distribution of run length appearance frequency in each of vertical and horizontal directions from run length found out by a run length detecting means 2 and finds out its feature, e.g. the peak value of frequency. A direction deciding means 4 compares the features (peak values) of vertical and horizontal appearance frequency found out by the means 3 with each other and decides the vertical or horizontal writing of an inputted document. Thereby, the character direction of a document can be accurately detected even in the case of using an original mixing halftone or graphic or an original of complex column composition.

Title: Semiconductor memory
Inventor: KITANO TOSHIHIRO
IPC: H01L27/10
Filed: 1990-07-30
Abstract: PURPOSE:To relieve the reduction of level of a word line by providing a circuit which changes the stand-by boosting capacity if a capacitor serving as the boosting capacity is destroyed. CONSTITUTION:The auxiliary capacitors 5 are connected in parallel to each other as a relief circuit, and the circuit is electrically switched. Then the relief circuit is switched to the capacitor 5 when a fuse 10 blows out. In a normal state, however, the fuse 10 is connected with a transistor TR 11 turned off. The levels of word lines are inverted by the inverters 7 and 8 with the TR 2 and 3 are turned off and an respectively. Thus a capacitor 4 is used. When the fuse 10 blows out, an L level is set by a high resistance TR 12 and the TR 11 is turned on. Then the input level of the inverter 8 is fixed at an L level. Therefore the levels are inverted by the inverters 7 and 8, and the TR 2 and 3 are turned off and on respectively. Thus the capacitor 5 is used. Thus a boosting circuit can work in a normal state with no use of the broken capacitor.

Filed: 1982-11-24
Abstract: PURPOSE:To obtain an amorphous material of good quality by forming an amorphous magnetic layer by a method reducing the deterioration of the magnetic characteristics due to oxidation, reducing the temperature rise of the surface of the substrate and suppressing crystallization extremely during the formation of said layer. CONSTITUTION:In the shown ion beam milling device, gaseous Ar is ionized by the acceleration of magnetron 3 in an electric charging part 1, accelerated to a cathode 4, electrically neutralized by a neutralizer and then accelerated as it is to a sputter target 7 in a target part 6 to be sputtered. Sputtered atoms are deposited on an evaporation substrate 8. Since the degree of vacuum in the target part 6 is kept at 10<-5>Torr at least, the amorphous film of good quality prevented from the influence due to the inclusion of gas or oxidation can be obtained. Since the beam is out of direct contact with the evaporation substrate, crystallization due to the temperature rise of the substrate can be suppressed.

Title: Control device for on-vehicle air conditioner
Inventor: KUMADA TATSUMI
IPC: B60H1/00
Filed: 1985-09-18
Abstract: PURPOSE:To prevent cool air due to ram pressure caused by a car running from hitting directly crews when a fan is suspended by allowing a blow-off mode selecting device to select a defrost blow-off mode when the fan is required to stop because a heater is found to be short of its heating capacity. CONSTITUTION:When either a relay 3 or a switch 9 is opened with a heater mode switch 7 turned on, and furthermore when an engine cooling water temperature detecting switch 11 is opened after the temperature has been found to be below a specified one, a main relay 16 is de-energized allowing a fan motor 14 to be suspended. In this case, a relay 2 is also de-energized, and a relay 4 is energized in place, then a selection signal equivalent to the closing of a defrost switch 8 is given to a servo unit 1 regardless of the closing of the heater mode switch 7 allowing an air plenum change-over door to be in a defrost blow-off mode. The relay 3 keeps the relay 2 holding the de-energized condition. This configuration prevents cool air from hitting crews when the fan is suspended.

Title: Automatic fading equalizer
Inventor: MACHIDA KAZUMI
IPC: H04B7/005
Filed: 1989-08-08
Abstract: PURPOSE:To always equalize an amplitude characteristic and a delay characteristic by constituting an equalization part so as to obtain a transmission function with a characteristic to remove the influence of a multiple reflection wave by using a delay signal and an amplitude adjusting signal outputted from a control part. CONSTITUTION:Generally for selective fading, when a direct wave is defined as D'= De<jomegat> and a multiply reflected wave is defined as R'=Re<jomega(t+tau)>, a synthesized wave is defined as C'=D'+R'=D(1+rhoe<jomegatau>)e<jomegat>. In such a condition, the tau is the difference of propagation delay time between the direct wave and the multiple reflected wave and the (rho) is an amplitude ratio R/D between the direct wave and the multiply reflected wave. When the output signal of the equalization part 2 is equal with the direct wave, it is considered that fading is equalized. Since the direct wave D' and the synthesized wave C' are expressed by the two formulas as mentioned above, when the transmission function of the equalization part 2 is defined as H(omega), it is enough to obtain the condition of D.(1+rhoe<jomegatau>)e<jomegat>.H(omega)=De<jomegat>. Accordingly, the control part 8 makes delay amount and amplitude adjustment amount to be applied to the equalization art 2 coincident with the tau and (rho) and the both delay characteristic and and amplitude characteristic are equalized together.
