Title: Peak detecting circuit
Inventor: SAKASHITA HIROHIKO
IPC: H03K5/13
Filed: 1982-09-16
Abstract: PURPOSE:To eliminate the effect of temperature, by subtracting an output and an input of a latch circuit as a subtractor and taking a borrow signal of the subtractor as a reading clock of the latch circuit so as to detect a maximum or a minimum value of an input signal. CONSTITUTION:An input signal of n-bit is stored temporarily in a latch 4, and an output signal of the latch 4 is applied to an adder 6. Further, the input signal is applied to the adder 6 via an inverter 5. The inverter 5 and the adder 6 form the subtractor, and when the input signal is larger than the output signal of the latch 4, the carry output of the adder 6 is brought into 0 and when smaller, brought into 1. When this carry output is at 0, a read clock is applied to the latch 4, the storage of the maximum value of the input signal is made possible and the constitution of a maximum peak detecting circuit is simplified.

Title: Ignition distributor for internal combustion engine
Inventor: NUMATA YOSHIMICHI
IPC: F02P7/02
Filed: 1995-06-28
Abstract: PURPOSE: To maintain excellent radio noise reducting effect by making the dielectric constant of a dielectric member have a larger value than the dielectric constant of a rotating body holding a rotary electrode, and projecting the electric discharge operation face of the rotary electrode more than the rotating body. CONSTITUTION: A tip electric discharge part 9 of a rotary electrode 1 facing a fixed electrode 7 is formed of a metal member 2, and a dielectric member 9 is provided at a part separated from the electric discharge operation face of the metal member 2 in contact with the metal member through a very small area. The dielectric constant of the dielectric member 9 is made higher than that of an insulating rotating body 10 holding the rotary electrode 1 and the dielectric member 9, and the electric discharge operation face of the rotary electrode 1 is projected more than the rotating body 10.  Thus, since a very small local electric discharge occurs at a contact area of the metal member 2 with the dielectric member 9, and an electric discharge is induced between the rotary electrode 1 and the fixed electrode 2 due to the very small local electric discharge, radio noise can be reduced sufficiently.

Abstract: PURPOSE:To make a channel region thinner by a method wherein a nitride film on a channel region is removed after a LOCOS oxidation is performed, and a semiconductor layer over the channel region is subjected to etching through the nitride film used as a mask. CONSTITUTION:After a nitride film 4 is formed on a part, where a transistor is to be formed, of a semiconductor layer 2 formed on an insulating substrate 1, a so-called LOCOS oxidation is performed through the nitride film 4 used as a mask. Next, the nitride film 4 on a channel region 6 is selectively removed and the semiconductor layer 2 of the channel region 6 is made to be thinner by etching performed onto it through the nitride used as a mask. As mentioned above, etching is performed using the nitride film 4 in a LOCOS process, whereby only the semiconductor layer 2 of the channel region 6 is made thinner.

Title: Method for accessing memory
Inventor: MCINTYRE KENNETH L JR
IPC: G06F12/0879
Filed: 1997-06-04
Abstract: PROBLEM TO BE SOLVED: To make it possible to design an efficient system for peripheral devices over a wide range by predicting whether or not a memory access to a specific area is gained in a prediction stage according to a history of access. SOLUTION: A data processing system 20 includes a data processor 22 which is roughly connected to an asynchronous memory 26 and a synchronous memory 28 through an external bus 24. Further, the data processor 22 includes a chip selecting circuit 40, which supplies three chip select signals to the asynchronous memory 26 and four chip select signals to the synchronous memory 28. When it is decided that memory access is directed to the specific area, a 2nd chip select signal is activated to complete the memory access. When it is decided that the memory access is to a 2nd area other than the specific area, a 2nd chip select signal is held inactive to finish the memory access to the specific area.

Patent JP-S5952152-A (JP)
Title: Heat exchanger
Inventor: MIYAGAWA TAKASHI
IPC: F24H7/04
Filed: 1982-09-17
Abstract: PURPOSE:To contrive to realize the favorably quick resing property for heat exchange and to improve the thermal efficiency by a method wherein ethylene glycol is heated by utilizing an electric heater as heat source so as to be able to release in a short time the heat which has accumulated for a certain fixed period of time from even the small power heat source. CONSTITUTION:The ethylene glycol 3 is sealed as heating medium in a main body 1. When the ethylene glycol 3 is heated by the electric heater 4 and at the same time water is led through a water intake 6 in a heat exchange pipe 5, the water is discharged from a water discharge port 7 even under the state that no pressure is applied to the water, because the water becomes lighter by being heated with the ethylene glycol 3 so as to travel upward. The employment of ethylene glycol, which has heat storaging property, as a heating medium is effective in the short time release of the heat, which has accumulated for a long period of time even with the small power electric heater, resulting in enabling to realize the favorably quick rising property. In addition, because ethylene glycol has a high boiling point, the loss of the ethylene glycol due to evaporation is small and the high thermal efficiency of the heat exchanger is resulted.

IPC: G03B9/08
Filed: 1979-12-15
Abstract: PURPOSE: To enable correct photographs that focus on desired subjects to be obtained by beforehand performing distance measurement or automatic focusing with a mimic subject then performing self-photographing without increasing operation systems.  
     CONSTITUTION: The device is so constituted that, when a shutter release member 7 is depressed while a self-timer means is held set, a lens starting member 5 is released of detention by the second stage of operation and is moved right and at the same time a holding detention lever 94 turns clockwise. While this causes a release member 7 to be detained, a holding bent piece 94c pushes the tail end 106b of a timer detention lever 106 to the left and releases the detention of an ankle 92; therefore, the self-timer starts operating. In this way, since the starting of self-photographing may be operated by the shutter release member, the self-photographing is made executable without increasing an operating system.
