Title: High voltage power source controller
Inventor: OKU JUNTARO
IPC: G03G15/00
Filed: 1990-06-22
Abstract: PURPOSE:To always lower the output current of a high voltage power source without depending upon the state of a load and to stably control it by equalizing the periods of energization starting of high voltage transformers of switching means, and deviating the energization periods of the transformers at each transformer. CONSTITUTION:A charging side switching transistor 42 and a transfer side switching transistor 52 are alternately turned ON at a timing for bringing the counted value of a reference counter 132 into coincidence with a frequency reference value m1. Thus, the period of energization starting of high voltage transformers 41, 51 is equal to twice of the value m1, and deviated by a half period. When the counted value of the counter 132 coincides with the value m1, the transistor 42 is turned ON this time. Accordingly, the energization periods of the transformer 41 for charging and the transformer 51 for transfer are not superposed.

Then, a p-type region 4 is formed on the surface of the layer 3 by injecting BF 2   +  ions, heat treatment is performed in N 2  atmosphere at 450W600°C for about 100 minutes, and a crystal-lattice defect layer 5 is remained near the boundary between layers 2 and 3. Thereafter, a switching diode is made by using  the substrate obtained by this method. A switching speed of 10μsec with errors of  about 20% can be obtained owing to the presence of the defect layer 5, and dispersion in speed is very small compared with that of normal Au diffusion.

Title: Pulse delay circuit
Inventor: IWASHITA MASAHARU
IPC: H03K5/13
Filed: 1985-07-23
Abstract: PURPOSE:To eliminate the need for readjustment of a delay time with every change of the period of a delayed pulse by changing automatically the delay time proportional to the period of the pulse to be delayed. CONSTITUTION:Suppose that a synchronizing signal (a) is decreased from a period T into a period T', an integration voltage (e) starts moving higher, an output voltage (f) of an operational amplifier 3 starts increasing, a charging current to a resistor R1 and a capacitor C1 is increased and the charging time is reduced, then the width (t) of an output pulse (b) is decreased into the width t'. When the width of the output pulse (b) is decreased, the integration voltage (e) is decreased, resulting that the integration voltage (e) kept nearly to a reference voltage 4. The change in the integration voltage (e) is smaller as the gain of the operational amplifier 3 is larger and zero when the gain is infinite. Then, the duty of an output pulse (b) is nearly constant, that is, the relation of (t/T (t'/T) exists regardless of the period T of the synchronizing signal (a). Thus, the output (b) is differentiated by a differentiation circuit 5 and a delay pulse (d) subject to waveform shaping by a waveform shaping circuit 6 is retarded in a uniform ratio against the period of the synchronizing signal (a).

Title: Temperature controlling circuit for warm water
Inventor: NAGAO SHIYOUJI
IPC: F23N5/14
Filed: 1980-11-19
Abstract: PURPOSE:To stabilize the temperature of warm water being taken out for use, by changing the operation setting temperature of a temperature controlling circuit for warm water of bridge type containing a water temperature detecting element, by a factor of time. CONSTITUTION:The bridge is composed of a water temperature detecting element 8 and resistors 9, 10 and 11, and a reversal input (d) of a differential amplifier 17 is set by resistors 10 and 11, while non-inversion input (c) is set by water temperature detecting elements 8 and 9. When the potential Vc of point (c) becomes higher than the potential Vd of point (d), the output (b) becomes in high level to drive a relay 15 to activate it to start combustion. The potential Va in the middle point (a) between a capacitor 7 and a resistor 3 is put in a differential amplifier 16 as a non-inversion input, lowering its potential following to the capacitor 7 being charged, and the potential Vb of an output (b) is also lowered along with the potential Va. As a potential Vb is connected to a point (d), a potential Vd is gradually lowered spending a time t2 to reach a set value, after a set time t1 elapses. That is, a set temperature is held at a fixed value during a time t1, rising up gradually spending a time t2, to reach a predetermined value. Therefore, excessive overshooting at the starting time of operation is prevented.

Title: Vertical type excavator
Inventor: KIMURA MASAYUKI
IPC: E21D1/03
Filed: 1995-06-29
Abstract: PURPOSE: To eliminate the need of an excessive thrust force by separately propelling mesail blades laid on the external surface of annular frame, and causing a frictional force to act along a propelling direction under soil pressure acting on a stationary mesail blade. CONSTITUTION: At the time of propelling an excavator, a mesail blade 4 is separated into one or several sections for each work, and the support of the reaction force of the blade 4 in progress is enough to cope with a propelling reaction force. In this case, the stationary mesail blade 4 is subjected to surrounding soil pressure, and shows a frictional force in a propelled direction. Thus, the support of only the frictional force is enough to cope with the propelling reaction force. Consequently, the necessity of receiving a reaction force from a segment is eliminated. Also. a partial earth retaining wall is required for the collapsible subsoil, and when the mesail blade 4 at a section needing the wall is pressed down and made to intrude, the wall can be provided for the intruded section. As a result, workability and safety with a cutting edge 6 can be improved.

Abstract: PROBLEM TO BE SOLVED: To improve the property of applying a charge to toner in the abut/nip region of a developing blade and a developing sleeve and to execute a stable developing process by specifying the relation between the 10-point average roughness of the surface of the developing sleeve an the weight average grain diameter of a one-component developer. SOLUTION: The applied developing sleeve 2 is worked so that the weight average grain diameter D of the one-component developer T used for forming an image and the 10-point average roughness Rz of the surface of the developing sleeve 2 become Rz>=D/2. Further, it is preferable that the developing sleeve 2 has a rugged surface. As a raggedness in this case, the sleeve 2 is worked so that the average interval Sm between projecting and recessed parts is <=20D when the average inclined angle θa of the projecting/recessed parts is <=45 deg. and <=10D when as the average inclined angle θa, 45 deg.<θa<90 deg. is obtained. Thus, when globular toner having high flowability and fine grain toner whose weight average grain diameter is <=5μm are used as well, the stable developing process is attained.
